description: Cold Dark Matter (CDM) models struggle to match the observations at galactic scales. The tension can be reduced either by dramatic baryonic feedback effects or by modifying the particle physics of CDM. Here, we consider an ultra-light scalar field DM particle manifesting a wave nature below a DM particle mass-dependent Jeans scale. For DM mass $m\sim10^{-22}{\rm eV}$, this scenario delays galaxy formation and avoids cusps in the center of the dark matter haloes. We use new measurements of half-light mass in ultra-faint dwarf galaxies Draco II and Triangulum II to estimate the mass of the DM particle in this model. We find that if the stellar populations are within the core of the density profile then the data are in agreement with a wave dark matter model having a DM particle with $m\sim 3.7-5.6\times 10^{-22}{\rm eV}$. The presence of this extremely light particle will contribute to the formation of a central solitonic core replacing the cusp of a Navarro-Frenk-White profile and bringing predictions closer to observations of cored central density in dwarf galaxies.

description: We present a systematic analysis of homogeneous and isotropic cosmologies in a particular Horndeski model with Galileon shift symmetry, containing also a $Λ$-term and a matter. The model, sometimes called Fab Five, admits a rich spectrum of solutions. Some of them describe the standard late time cosmological dynamic dominated by the $Λ$-term and matter, while at the early times the universe expands with a constant Hubble rate determined by the value of the scalar kinetic coupling. For other solutions the $Λ$-term and matter are screened at all times but there are nevertheless the early and late accelerating phases. The model also admits bounces, as well as peculiar solutions describing "the emergence of time". Most of these solutions contain ghosts in the scalar and tensor sectors. However, a careful analysis reveals three different branches of ghost-free solutions, all showing a late time acceleration phase. We analyze the dynamical stability of these solutions and find that all of them are stable in the future, since all their perturbations stay bounded at late times. However, they all turn out to be unstable in the past, as their perturbations grow violently when one approaches the initial spacetime singularity. We therefore conclude that the model has no viable solutions describing the whole of the cosmological history, although it may describe the current acceleration phase. We also check that the flat space solution is ghost-free in the model, but it may acquire ghost in more general versions of the Horndeski theory.

description: Recent non-detection of gravitational-wave backgrounds from pulsar timing arrays casts further uncertainty on the evolution of supermassive black hole binaries. We study the capabilities of current gravitational-wave observatories to detect individual binaries and demonstrate that, contrary to conventional wisdom, some are in principle detectable throughout the Universe. In particular, a binary with rest-frame mass $\gtrsim10^{10}\,M_\odot$ can be detected by current timing arrays at arbitrarily high redshifts. The same claim will apply for less massive binaries with more sensitive future arrays. As a consequence, future searches for nanohertz gravitational waves could be expanded to target evolving high-redshift binaries. We calculate the maximum distance at which binaries can be observed with pulsar timing arrays and other detectors, properly accounting for redshift and using realistic binary waveforms.

description: Hard X-ray spectra of 28 bright Seyfert galaxies observed with INTEGRAL were analyzed together with the X-ray spectra from XMM-Newton, Suzaku and RXTE. These broad-band data were fitted with a model assuming a thermal Comptonization as a primary continuum component. We tested several model options through a fitting of the Comptonized continuum accompanied by a complex absorption and a Compton reflection. Both the large data set used and the model space explored allowed us to accurately determine a mean temperature kTe of the electron plasma, the Compton parameter y and the Compton reflection strength R for the majority of objects in the sample. Our main finding is that a vast majority of the sample (20 objects) is characterized by kTe < 100 keV, and only for two objects we found kTe > 200 keV. The median kTe for entire sample is 48(-14,+57) keV. The distribution of the y parameter is bimodal, with a broad component centered at ~0.8 and a narrow peak at ~1.1. A complex, dual absorber model improved the fit for all data sets, compared to a simple absorption model, reducing the fitted strength of Compton reflection by a factor of about 2. Modest reflection (median R ~0.32) together with a high ratio of Comptonized to seed photon fluxes point towards a geometry with a compact hard X-ray emitting region well separated from the accretion disc. Our results imply that the template Seyferts spectra used in AGN population synthesis models should be revised.

The use of private military and security companies in international society: contestation and legitimation of state practice
Creators: name: Matteo, Daniel
Publisher: name: University of Westminster
Year: 2015

description: The objective of this dissertation is to understand how the legitimacy of the state’s international use of PMSCs is evolving in contemporary international society. The first part of the dissertation develops an analytical framework that combines theoretical propositions of the English School and the ‘German’ constructivist strand with a reflective-analyticist philosophical ontology and with content and discourse analytical methods. The empirical part of the dissertation provides an overview of contemporary state practice, investigates how international society has responded to state practice in the UN Security Council and UN General Assembly, and finally analyses the roles of members of world society in creating and shaping this discourse. The empirical analysis points to two major driving forces behind the increased legitimation of the practice. First, the recursive relationship between behaviour and norms means that widespread use of PMSCs reinforces legitimacy. Second, normative shifts in international society have contributed to the legitimation of the practice. On the one hand, norms that are in tension with an expanded PMSC use have become weaker or sidelined, if still strongly supported by some actors: this is the anti-mercenary norm, and particular understandings of self-determination and the monopoly on the legitimate use of force. On the other hand, and partly linked to the weakening of the latter norms, human rights have gained strength as legitimacy principles. In the contestation over the state use of PMSCs, conflicting moves toward legitimation and delegitimation do not cancel each other out. Rather, structural and more immediate factors put strategic efforts and inadvertent moves of legitimation at an advantage while at the same time marginalizing calls for a reduction or prohibition of the state practice. I examine not only how human rights contribute to the legitimation of the practice, but also why and how actors that seek to limit, contain, or reverse the state practice have increasingly lost ground. Overall, the dissertation contributes to empirical research by substantiating claims of an increased legitimation of PMSC use. It also contributes to the broader IR discipline by proposing a change in perspective: away from an atomistic focus on norms to a more holistic study of legitimacy and legitimation. The resulting framework is particularly fruitful for the analysis of other controversial issues of international relations.
Researching suicidal behaviours by offenders serving community based sentences: a near-lethal approach
Creators: name: Mackenzie, Jay-marie
Publisher: name: University of Westminster
Year: 2015

description: Suicide, a global problem, affects individuals from diverse backgrounds. Higher at-risk groups include vulnerable populations, such as offenders and prisoners. Most suicide research focuses on prisoners with little focus on probation populations. The lived experiences of probation clients who have made suicide attempts has not previously been explored. Furthermore, research on experiences of probation staff managing suicidal offenders is limited. Consequently, the current research explored the experiences of probation clients who made near-lethal attempts, as well as the experiences of staff managing these clients, and strategies to prevent suicide. Study 1 explored probation staff experiences of managing suicidal clients through in-depth interviews. Findings indicate that staff felt inadequate in managing these issues, but training and experience facilitated better management techniques. Studies 2a & 2b explored the perspective of individuals serving probation sentences who had made near-lethal attempts. Findings suggest that the suicidal state was experienced in relation to perceived loss of control, which often related to their probation process. Clients felt that non-judgmental listening prevented suicide attempts. However, disclosure was sometimes unlikely due to a fear of being judged or lacking trust in others. Study 3 employed 3-6 month follow-up interviews to explore changes in clients’ perspectives. Findings suggest that following reflection on their attempts, clients’ time perception fluctuated. For example, time leading up to the attempt was perceived as slow whilst the actual attempt was quick and impulsive, and following the attempt time slowed down. This slowness in time prior to the suicide attempt could be an opportunity for interventions. Findings highlight the need for extra support regarding negative coping strategies in order to prevent offending and suicide. Moreover, clients receiving support for their suicidal feelings and maladaptive coping mechanisms did not make further attempts. Study 4 compared the experiences and views of probation clients with staff. Findings demonstrate similar views in terms of when and why suicides occur, and what can be done to prevent suicide. However, poor communication between the two parties was a barrier to suicide management. The unique contribution of this program of research lies in its understanding of suicide from the perspectives of probation clients who have experienced it; providing unique understandings about clients at high risk of suicide, ways of preventing suicide, and what barriers exist for clients who need help.
CHY formula and MHV amplitudes

description: In this paper, we study the relation between the Cachazo-He-Yuan (CHY) formula and the maximal-helicity-violating (MHV) amplitudes of Yang-Mills and gravity in four dimensions. We prove that only one special rational solution of the scattering equations found by Weinzierl support the MHV amplitudes. Namely, localized at this solution, the integrated CHY formula reproduces the Parke-Taylor formula for Yang-Mills amplitudes as well as the Hodges formula for gravitational amplitudes. This is achieved by developing techniques, in a manifestly Möbius covariant formalism, to explicitly compute relevant reduced Pfaffians/determinants. We observe and prove two interesting properties (or identities), which facilitate the computations. We also check that all the other $(n-3)!-1$ solutions to the scattering equations do not support the MHV amplitudes, and prove analytically that this is indeed true for the other special rational solution proposed by Weinzierl, that actually supports the anti-MHV amplitudes.

An Approach to Managing and Organizing Text Documents Using Intelligent Text Analysis
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2017

description: Regarding the fact that stored data occupies a large space in organizations and retention systems and information management that has been resulted in gigantic data warehouses, the need for extracting an appropriate model is felt increasingly. Text mining is one of the most significant methods for extracting a useful and appropriate model that helps organizations in achieving their goals through extraction and adaption of knowledge out of data sets. Those methods allow for a new horizon for trading and protecting intellectual property of authors’ works. In this paper, a new approach is needed to decipher the text patterns to organize an intelligent text analysis. The main purpose of the paper is applying a proper method of preserving the works of writers, scholars and text documents. Regarding the number of those works and documentary management systems the size of available data has been increased considerably. In order to uncover the implicit knowledge out of this data with considerable usefulness for users a specific method is required that has been practiced in the data mining field. Much of this available data is unstructured or semi-structured text which one can use it in addition to data mining methods, technologies such as natural language processing, intelligent analysis and Science Statistics used.

A Context Aware Recommender System for Mobile Phone Selection Using Combination of Elimination Method and Analytic Hierarchy Processing
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2017

description: Recommender systems suggest proper items to customers based on their preferences and needs. Needed time to search is reduced and the quality of customer’s choice is increased using recommender systems. The context information like time, location and user behaviors can enhance the quality of recommendations and customer satisfication in such systems. In this paper a context aware recommender system is designed and implemented in android smart phones to help customers select mobile phones. The system removes ineffective criteria on user’s purcheses using customer mobile phones’ sensor data. Then creates analytic hierarchy processing tree and computes weights. Finally the recommender system recommends proper mobile phone to user. The system selects and recommends suitable phones using combination of elimination method and analytic hierarchy processing (AHP). The context aware recommender system is used by mobile phone customers to assess recomendation satisfication and user interface design satisfication. In addition a traditional non-context aware recommender system is used by users to compare the recommendation results in two different systems. The article concludes that using context information can improve the recommendation quality and user satisfication. Because of decreasing criteria and pair-wised comparisions, the user interface design satisfication improves a little too.

description: In this paper we present a spectral decomposition of solutions to relativistic wave equations described on horizon penetrating hyperboloidal slices within a given Schwarzschild-black-hole background. The wave equa- tion in question is Laplace-transformed which leads to a spatial differential equation with a complex parameter. For initial data which are analytic with respect to a compactified spatial coordinate, this equation is treated with the help of the Mathematica-package in terms of a sophisticated Taylor series analysis. Thereby, all ingredients of the desired spectral decomposition arise explicitly to arbitrarily prescribed accuracy, including quasi normal modes, quasi normal mode amplitudes as well as the jump of the Laplace-transform along the branch cut. Finally, all contributions are put together to obtain via the inverse Laplace transformation the spectral de- composition in question. The paper explains extensively this procedure and includes detailed discussions of relevant aspects, such as the definition of quasi normal modes and the question regarding the contribution of infinity frequencies modes to the early time response of the black hole.

description: We present a new approach to describe hydrodynamics carrying non-Abelian macroscopic degrees of freedom. Based on the Kaluza-Klein compactification of a higher-dimensional neutral dissipative fluid on a group manifold, we obtain a d=4 colored dissipative fluid coupled to Yang-Mills gauge field. We calculate the transport coefficients of the new fluid, which show the non-Abelian character of the gauge group. In particular, we obtain group-valued terms in the gradient expansions and response quantities such as the conductivity matrix and the chemical potentials. While using SU(2) for simplicity, this approach is applicable to any gauge group. Resulting a robust description of non-Abelian hydrodynamics, we discuss some links between this system and quark-gluon plasma and fluid/gravity duality.

description: We theoretically consider the temporal dynamics of two coupled spin qubits (e.g., semiconductor quantum dots) driven by the inter-qubit spin-spin coupling. The presence of environmental noise (e.g., charge traps, nuclear spins, random magnetic impurities) is accounted for by including random magnetic field and random inter-qubit coupling terms in the Hamiltonian. Both Heisenberg coupling and Ising coupling between the spin qubits are considered, corresponding respectively to exchange and capacitive gates as appropriate for single spin and singlet-triplet semiconductor qubit systems, respectively. Both exchange (Heisenberg) and capacitive (Ising) coupling situations can be solved numerically exactly even in the presence of noise, leading to the key findings that (i) the steady-state return probability to the initial state remains close to unity in the presence of strong noise for many, but not all, starting spin configurations, and (ii) the return probability as a function of time is oscillatory with a characteristic noise-controlled decay toward the steady-state value. We also provide results for the magnetization dynamics of the coupled two-qubit system. Our predicted dynamics can be directly tested in the already existing semiconductor spin qubit setups providing insight into their coherent interaction dynamics. Retention of the initial state spin memory even in the presence of strong environmental noise has important implications for quantum computation using spin qubits.
description: 11.5 pages, 18 figures. Added new figures to emphasize the effects of charge noise.

description: The temperature dependence of microwave-induced resistance oscillations (MIRO), according to the theory, originates from electron-electron scattering. This scattering affects both the quantum lifetime, or the density of states, and the inelastic lifetime, which governs the relaxation of the nonequilibrium distribution function. Here, we report on MIRO in an ultrahigh mobility ($μ> 3 \times 10^7$ cm$^2$/Vs) 2D electron gas at $T$ between $0.3$ K and $1.8$ K. In contrast to theoretical predictions, the quantum lifetime is found to be $T$-independent in the whole temperature range studied. At the same time, the $T$-dependence of the inelastic lifetime is much \emph{stronger} than can be expected from electron-electron interactions.
The importance of positive and negative well-being in older people; associations with psychosocial factors, cortisol and cognitive performance
Creators: name: Fredhoi, Cathrine
Publisher: name: University of Westminster
Year: 2015

description: During the past decades, studies have attempted to define predictive factors that are associated with successful ageing. The extent to which positive and negative well-being, as two independent dimensions (Huppert and Whittington, 2003), are related to ageing is examined in this research. The first aim was to confirm the independence of positive and negative well-being, secondly, to establish if demographic and psychosocial factors, a biomarker of health (cortisol) and cognitive functioning are associated with positive and negative well-being and thirdly, to determine if associations found would remain stable or change over a three-year period. Fifty older adults (aged 59-91, mean=74, SD±7, 34 females) participated at Time 1 and 75% of the participants (n=37, aged 63-87, mean=74, SD±6, 25 females) participated at Time 2. Demographical and psychosocial data were collected at an initial home visit, followed by two diurnal cycles of cortisol collections (8 samples per day) and cognitive assessment at a second visit. Four well-being quadrants (LowPos/LowNeg, LowPos/HighNeg,HighPos/LowNeg and HighPos/HighNeg) were found, supporting the theory that positive and negative well-being are two relatively independent domains. There was a significant main effect of negative well-being on health, quality of life and social support while positive well-being had no effect. There was also a main effect of positive well-being on successful ageing and spirituality while negative well-being had no effect. Results of the overall cortisol concentrations revealed an interaction between dimensions of well-being. The HighPos/LowNeg participants had significantly lower post-awakening cortisol compared to the rest of the group. Cognitive performance was inversely correlated with age for those who scored low on positive well-being and on those who scored high on the negative well-being, suggesting that those who reported high positive well-being and low negative well-being were likely to experience better age-related cognitive function. There was no change in positive and negative well-being over a three-year period. Despite this, participants reported worse health and less social support. The results from the cortisol data indicated a reduced dynamic of the awakening cortisol response over the 3-year period but suggested that patterns of cortisol secretion remained largely consistent over time, regardless of changes in psychosocial factors. This work has replicated and extended previous findings on positive and negative well-being, as measured by the GHQ-30, and developed our understanding of how and to what extent positive and negative well-being can be said to function as two relatively independent domains. This thesis has further demonstrated the utility of including a variety of factors, such as psychosocial, cortisol and cognitive performance in order to measure determinants of successful ageing.

description: Background: Previous research has shown that exposure to bullying is linked to long-term adverse mental health consequences. However, prospective studies examining the persistence of bullying, using information from repeated time points, are limited. The aim of this study was to examine, firstly, the extent to which exposure to bullying among adolescents in Sweden changes between grades 9 (age 15–16) and 11 (age 17–18) (i.e., before and after the transition from lower to upper secondary school); secondly, whether being bullied in grade 9 or 11 is associated with depression and anxiety symptoms at age 20–21; and thirdly, if being bullied in both grade 9 and 11 is linked to an even higher likelihood of subsequent depression and anxiety symptoms. Potential differences by gender were investigated throughout. Methods: Data was derived from the Swedish cohort study Futura01 involving individuals attending grade 9 in the school year 2016/17 (n = 2323). We utilised self-reported information from three survey waves conducted in 2017, 2019, and 2022, and linked registry information on sociodemographic characteristics. Bullying was assessed using a single item in waves 1 and 2. Depression and anxiety symptoms were measured using the Patient Health Questionnaire-4 (PHQ-4) in wave 3. Gender stratified binary logistic regressions were performed. Results: Among those who were bullied in grade 9, 22.6% of males and 35.8% of females continued to experience bullying in grade 11. For females, exposure to bullying in grade 9 or 11 was associated with an increased likelihood of reporting depression and anxiety symptoms at age 20–21, with the highest odds for those bullied at both time points. For males, only one statistically significant association was identified – specifically, between being bullied in grade 9 and subsequent depression symptoms. Conclusions: For a majority of adolescents who experience bullying in lower secondary school, but not all, the transition to upper secondary school proves to be beneficial as the bullying typically does not persist. However, bullying can have long-term health effects, in particular for females. These findings emphasise the importance of effective measures to address bullying within schools.

description: We discuss the transition paths in a coupled bistable system consisting of interacting multiple identical bistable motifs. We propose a simple model of coupled bistable gene circuits as an example, and show that its transition paths are bifurcating. We then derive a criterion to predict the bifurcation of transition paths in a generalized coupled bistable system. We confirm the validity of the theory for the example system by numerical simulation. We also demonstrate in the example system that, if the steady states of individual gene circuits are not changed by the coupling, the bifurcation pattern is not dependent on the number of gene circuits. We further show that the transition rate exponentially decreases with the number of gene circuits when the transition path does not bifurcate, while a bifurcation facilitates the transition by lowering the quasi-potential energy barrier.

description: We report on high-order magnetoplasmon resonances detected in photoresistance in high-mobility GaAs quantum wells. These resonances manifest themselves as a series of photoresistance extrema in the regime of Shubnikov-de Haas oscillations. Extending to orders above 20, the extrema exhibit alternating strength, being less (more) pronounced at even (odd) order magnetoplasmon modes. This experimental technique provides sensitive and elegant means to detect and investigate multiple magnetoplasmon modes and could be applied to other systems.

description: This commentary focuses on my photographic and film work that takes the relationship between children and computers as its theme. The text opens with a description of my earliest digital research project In a Shaded Place (1995), which explored the introduction of computers into early learning. I then go on to discuss a series of projects that focus similarly on the relationship between children and digital culture from this period to 2014. Over a series of chapters I discuss my own practice in relation to the early impact of the computer on photography, the impact of the introduction of the Internet on children and the development and impact of computer gaming on young people. I also discuss the enduring interest in childhood as a theme in photography, reflecting on the work of key artists, curators and writers working in my field whom I have exhibited and been published alongside over the period covered by the commentary. All of the projects included here address the question: How has the computer (and, by extension, the information age) affected the ways in which we describe and depict ourselves? Over the period covered by this commentary there has an unprecedented shift in the understanding of the role and function of photography. There has also been a marked shift in attitude to the representation of the child in society. Both of these subjects have deeply informed my practice. I conclude my commentary with a description and analysis of my 2009 project The Skater and a description of what I perceive as my own contribution to new knowledge, which includes the impact of my work on the understanding of the representation for the child in photography and also its implied critique of the impact of the computer on photography at the beginning of the digital age.

description: We present the first complete Markov chain Monte Carlo analysis of cosmological models with evolving cosmic (super)string networks, using the unconnected segment model in the unequal-time correlator formalism. For ordinary cosmic string networks, we derive joint constraints on Lambda cold dark matter (CDM) and string network parameters, namely the string tension Gmu, the loop-chopping efficiency c_r and the string wiggliness α. For cosmic superstrings, we obtain joint constraints on the fundamental string tension Gmu_F, the string coupling g_s, the self-interaction coefficient c_s, and the volume of compact extra dimensions w. This constitutes the most comprehensive CMB analysis of LambdaCDM cosmology + strings to date. For ordinary cosmic string networks our updated constraint on the string tension is, in relativistic units, Gmu<1.1x10^-7, while for cosmic superstrings our constraint on the fundamental string tension is Gmu_F<2.8x10^-8, both obtained using Planck2015 temperature and polarisation data.

The cold gas component in GASP ram-pressure stripped galaxies
Creators: name: Moretti, Alessia
Publisher: name: Zenodo
Year: 2023

description: Galaxies living in dense environments have star formation histories shaped by their journey within the cluster potential. In particular, they can see their star formation in the disk suppressed on a short timescale by the ram-pressure stripping. Galaxies in nearby clusters (z~0.05) subject to ram pressure stripping within the GASP survey show also evidence of star formation along the tails of stripped gas, as traced by their ionized gas emission. At the same time, an increased star formation is also seen in their disks before the stripping completes. I will describe how the star formation proceeds both globally and locally (on scales of ~1kpc) in the peculiar environment offered by galaxies subject to ram-pressure stripping which are strongly influenced by the cluster environment. In particular, I will show how the infalling of galaxies in the clusters cause an overabundance of cold gas in the disks, and how this reflects in the global star formation efficiency. At the same time, I will present the scaling relations on ~1kpc scale that have been derived by coupling together MUSE and ALMA data on the GASP sample. The results are important not only to characterize the star formation in nearby RPS galaxies, but also to provide a link between local and higher redshift samples, where clumpy star forming regions dominate.
title: Pensions, financialisation, and the psychological contract - how do ‘experts’ make pension choices and whom do they trust to provide pension information?

description: Higher life expectancy and recent changes to legislation have brought the issue of occupational pensions to greater prominence. How people make pension choices, what information they use, and whom they trust when doing this are therefore important issues for individuals and society. This study aims to shed light on these questions. In doing so this thesis contributes to theory by using a combination of financialisation and the psychological contract to take a different view of the pension landscape in the UK and contributes to practice by considering the response of individuals to the complexity of pension decisions.
This DBA thesis uses a case study approach to explore the views and experiences in relation to pensions of a group of employees with considerable financial expertise at the Institute of Chartered Accountants of Scotland. The study is qualitative, inductive, and adopts an interpretivist perspective. Information was gathered from semi-structured interviews, which allowed for consistency, but also provided an opportunity for individual comment and feedback from participants. The data was analysed thematically and the themes that emerged were used to frame the resulting study.
The study’s findings show that pension decisions are complex and many individuals, despite good intentions and expertise, put more immediate life events and priorities ahead of pension investment. They tend to focus on input factors, particularly their bottom-line salary, rather than the output from pension investment that will accrue in future. Fundamental to pension decisions are the high levels of trust of employers, pension providers, and the lack of trust in financial advisers. These findings mean there is the potential that pensions will not meet the needs of employees in retirement.
The study makes a number of recommendations – that financial education (including pensions) is taught in schools, pension scheme members should have an informed choice of default fund, the default pension fund is monitored for performance and suitability, there is greater use of financial advice, and that communication from employers is improved. These recommendations will help to improve pensions for future generations of employees.

description: Working with a pion mass $m_π\approx 150$ MeV, we study $ππ$ and $Kπ$ scattering using two flavours of non-perturbatively improved Wilson fermions at a lattice spacing $a\approx 0.071$ fm. Employing two lattice volumes with linear spatial extents of $N_s=48$ and $N_s=64$ points and moving frames, we extract the phase shifts for p-wave $ππ$ and $Kπ$ scattering near the $ρ$ and $K^*$ resonances.Comparing our results to those of previous lattice studies, that used pion masses ranging from about 200 MeV up to 470 MeV, we find that the coupling $g_{ρππ}$ appears to be remarkably constant as a function of $m_π$.

description: The poster was presented at the 8th Federation of European Zeolite Associations (FEZA) held online on the 5-9 July 2021. With the aim to reduce greenhouse emissions, the recent perspectives of research are now focused not only on the development and optimization of technologies for carbon dioxide sequestration (CCS), but mainly on the conception and demonstration of new strategies for carbon dioxide utilisation (CCU) for the production of bulk chemicals or fuels [1]. In this context, particular attention has been paid on the direct catalytic hydrogenation of CO2 into dimethyl ether (DME), an environmentally friendly fuel compatible with use in conventional diesel engines.
Calorimetric observation of single He2* excimers in a 100 mK He bath

description: We report the first calorimetric detection of individual He2* excimers within a bath of superfluid 4He. The detector used in this work is a single superconducting titanium transition edge sensor (TES) with an energy resolution of ~1 eV, immersed directly in the helium bath. He2* excimers are produced in the surrounding bath using an external gamma-ray source. These excimers exist either as short-lived singlet or long-lived triplet states. We demonstrate detection of both states: in the singlet case the calorimeter records the absorption of a prompt 15 eV photon, and in the triplet case the calorimeter records a direct interaction of the molecule with the TES surface, which deposits a distinct fraction of the 15 eV, released upon decay, into the surface. We also briefly discuss the detector fabrication and characterization.

description: Strongly anisotropic media where the principal components of electric permittivity or magnetic permeability tensors have opposite signs are termed as hyperbolic media. Such media support propagating electromagnetic waves with extremely large wavevectors exhibiting unique optical properties. However in all artificial and natural optical materials studied to date, the hyperbolic dispersion originates solely from the electric response. This restricts material functionality to one polarization of light and inhibits free-space impedance matching. Such restrictions can be overcome in media having components of opposite signs for both electric and magnetic tensors. Here we present the experimental demonstration of the magnetic hyperbolic dispersion in three-dimensional metamaterials. We measure metamaterial isofrequecy contours and reveal the topological phase transition between the elliptic and hyperbolic dispersion. In the hyperbolic regime, we demonstrate the strong enhancement of thermal emission, which becomes directional, coherent and polarized. Our findings show the possibilities for realizing efficient impedance-matched hyperbolic media for unpolarized light.
