First-order derivative of cluster size as a new signature of phase transition in heavy ion collisions at intermediate energies

description: The phenomenon of liquid-gas phase transition occurring in heavy ion collisions at intermediate energies is a subject of contemporary interest. Phase transition is usually characterized by the specific behaviour of state variables like pressure, density, energy etc. In heavy ion collisions there is no direct way of accessing these state variables and hence unambiguous detection of phase transition becomes difficult. This work establishes that signatures of phase transition can be extracted from the observables which are easily accessible in experiments and these have similar behaviour as the state variables. The temperature dependence of the first order derivative of the order parameters related to the largest and second largest cluster size (produced in heavy ion collisions) exhibit similar behavior as that of the variation of specific heat at constant volume Cv which is an established signature of first order phase transition. This motivates us to propose these derivatives as confirmatory signals of liquid-gas phase transition. The measurement of these signals in easily feasible in most experiments as compared to the other signatures like specific heat, caloric curve or bimodality. This temperature where the peak appears is designated to be the transition temperature and the effect of certain parameters on this has also been examined.

description: Critically analysing the behaviour of peer-to-peer accommodation hosts provides alternative ways of understanding hospitality and tourism experiences. This paper offers an analysis of how Airbnb hosts in Australia talk and interact with guests and the contextual constructs which shape this behaviour. We applied a theoretical framework of service language and a multiple case study methodology to explore the perspectives of different Superhosts. Our analysis suggests peer-to-peer exchanges are influenced by the nature of accommodation as a commercial home. Talk and interaction varies through pre-arrival, arrival, occupancy, departure and post-departure. Our findings contribute to research regarding peer-to-peer accommodation hosting, interpersonal communication and service interactions in commercial homes, and guide a design of hospitality-centric experiences in a changing accommodation environment.

description: This exploratory study critically analyzes service providers' spoken language in luxury (five-star) hotels. Informed by an interpretive research paradigm and a grounded theory methodology incorporating a concurrent process of data collection and analysis, semi-structured interviews were undertaken with 22 service providers employed in luxury hotels in the Central Business District of Sydney, Australia. Our findings reveal that service providers open and close their service encounters with hotel guests by using structured, and often rehearsed, sequences of verbal exchange. Between the opening and closing sequences, service providers' interactions and conversations with guests vary depending on the situations arising during encounters. Processes that allowed for flexibility and adaptation during encounters were important for transitions in service providers' verbal exchanges and building relationships with guests. A substantive grounded theory model for critically analyzing the language of service in Australian luxury (five-star) hotels is presented. Our research contributes to theoretical and applied understandings of service in five-star hotels broadly, and the language of service in particular. It adds to knowledge of the complexities and multifaceted characteristics of service provider – customer interactions, relevant to hospitality and broader service contexts.

description: What is information? Is it physical? We argue that in a Bayesian theory the notion of information must be defined in terms of its effects on the beliefs of rational agents. Information is whatever constrains rational beliefs and therefore it is the force that induces us to change our minds. This problem of updating from a prior to a posterior probability distribution is tackled through an eliminative induction process that singles out the logarithmic relative entropy as the unique tool for inference. The resulting method of Maximum relative Entropy (ME), which is designed for updating from arbitrary priors given information in the form of arbitrary constraints, includes as special cases both MaxEnt (which allows arbitrary constraints) and Bayes' rule (which allows arbitrary priors). Thus, ME unifies the two themes of these workshops -- the Maximum Entropy and the Bayesian methods -- into a single general inference scheme that allows us to handle problems that lie beyond the reach of either of the two methods separately. I conclude with a couple of simple illustrative examples.

description: It is a known fact that not all controllable systems can be asymptotically stabilized by a continuous static feedback. Several approaches have been developed throughout the last decades, including time-varying, dynamical and even discontinuous feedbacks. In the latter case, the sample-and-hold framework is widely used, in which the control input is held constant during sampling periods. Consequently, only practical stability can be achieved at best. Existing approaches often require solving optimization problems for finding stabilizing control actions exactly. In practice, each optimization routine has a finite accuracy which might influence the state convergence. This work shows, what bounds on optimization accuracy are required to achieve prescribed stability margins. Simulation studies support the claim that optimization accuracy has high influence on the state convergence.

A twistor formulation of the heterotic D=10 superstring with manifest (8,0) worldsheet supersymmetry

description: We propose a new formulation of the heterotic $D=10$ Green-Schwarz superstring whose worldsheet is a superspace with two even and eight odd coordinates. The action is manifestly invariant under both target-space supersymmetry and a worldsheet reparametrisation supergroup. It contains only a finite set of auxiliary fields. The key ingredient are the commuting spinor (twistor) variables, which naturally arise as worldsheet superpartners of the target space Grassmann coordinates. These spinors parametrise the sphere $S^8$ regarded as a coset space of the $D=10$ Lorentz group. The sphere is associated with the lightlike vector of one of the string Virasoro constraints. The origin of the on-shell $D=10$ fermionic kappa symmetry of the standard Green-Schwarz formulation is explained. An essential and unusual feature is the appearance of the string tension only on shell as an integration constant.

description: [abridged] The role of magnetic fields in the process of star formation is a matter of continuous debate. Clear observational proof of the general influence of magnetic fields on the early phase of cloud collapse is still pending. First results on Bok globules with simple structures indicate dominant magnetic fields across large spatial scales (Bertrang+2014). The aim of this study is to test the magnetic field influence across Bok globules with more complex density structures. We apply near-infrared polarimetry to trace the magnetic field structure on scales of 10^4-10^5au in selected Bok globules. The combination of these measurements with archival data in the optical and sub-mm wavelength range allows us to characterize the magnetic field on scales of 10^3-10^6au. We present polarimetric data in the near-infrared wavelength range for the three Bok globules CB34, CB56, and [OMK2002]18, combined with archival polarimetric data in the optical wavelength range for CB34 and CB56, and in the sub-millimeter wavelength range for CB34 and [OMK2002]18. We find a strong polarization signal (P>2%) in the near-infrared and strongly aligned polarization segments on large scales (10^4-10^6au) for all three globules. This indicates dominant magnetic fields across Bok globules with complex density structures. To reconcile our findings in globules, the lowest mass clouds known, and the results on intermediate (e.g., Taurus) and more massive (e.g., Orion) clouds, we postulate a mass dependent role of magnetic fields, whereby magnetic fields appear to be dominant on low and high mass but rather sub-dominant on intermediate mass clouds.

description: We study locally gated silicene nanoribbons as spin active devices. We find that the gated segments of nanoribbons with zigzag edge can be used to perform a spin inversion for the electron spins injected with an in-plane orientation. The strong intrinsic spin-orbit coupling for low Fermi energy in presence of an external vertical electric field provides a fast spin precession around the axis perpendicular to the silicene plane. The spin inversion length can be as small as 10 nm. On the other hand in the armchair nanoribbons the spin inversion occurs via the Rashba effect which is weak and the spin inversion lengths are of the order of $μ$m.
Independence of the grossone-based infinity methodology from non-standard analysis and comments upon logical fallacies in some texts asserting the opposite

description: This commentary considers non-standard analysis and a recently introduced computational methodology based on the notion of \G1 (this symbol is called \emph{grossone}). The latter approach was developed with the intention to allow one to work with infinities and infinitesimals numerically in a unique computational framework and in all the situations requiring these notions. Non-standard analysis is a classical purely symbolic technique that works with ultrafilters, external and internal sets, standard and non-standard numbers, etc. In its turn, the \G1-based methodology does not use any of these notions and proposes a more physical treatment of mathematical objects separating the objects from tools used to study them. It both offers a possibility to create new numerical methods using infinities and infinitesimals in floating-point computations and allows one to study certain mathematical objects dealing with infinity more accurately than it is done traditionally. In these notes, we explain that even though both methodologies deal with infinities and infinitesimals, they are independent and represent two different philosophies of Mathematics that are not in a conflict. It is proved that texts \cite{Flunks, Gutman_Kutateladze_2008, Kutateladze_2011} asserting that the \G1-based methodology is a part of non-standard analysis unfortunately contain several logical fallacies. Their attempt to prove that the \G1-based methodology is a part of non-standard analysis is similar to trying to show that constructivism can be reduced to the traditional mathematics.

description: The literature on Information Technology (IT) enabled innovation, like innovation literature more generally, has focused predominantly on work conducted in ‘developed’ countries. Historically this has been due to a lack of empirical evidence collected in ‘developing’ countries and access to comparable examples of innovation. This situation results in the application of developed world ideas to innovation in the developing world. Whether and how the adoption of IT-enabled innovation in developing countries differs from developed countries thereforeremains an unexplored question (World Bank 2008). These findings bring into question the direct application in developing countries of innovation models and frameworks created through the study of innovations in developed countries, specifically of disruptive innovation. To explore this hypothesis the adoption of internet and mobile banking (IMB) in India and Australia are discussed. It was found that in India IMB satisfied an unmet customer need that had not previously existed in the form of banking (Christensen & Raynor 2003) and in the process disrupted traditional and informal finance methods. On the other hand, the adoption of IMB in Australia improvedand sustained existing banking methods, providing greater efficiency. IT-enabled innovation appears to follow an opposite path in developed nations to that in developing nations driven by differences in consumer needs.

description: We show that longwavelength excitations of the quark-gluon plasma are described by simple kinetic equations which represent the exact equations of motion at leading order in $g$. Properties of the so-called ``hard thermal loops'', i.e. the dominant contributions to amplitudes with soft external lines, find in this approach a natural explanation. In particular, their generating functional appears here as the effective action describing long wavelength excitations of the plasma.

description: Hexagonal boron nitride (h-BN) shares a similar layered crystal structure as graphite. Graphite is a semimetal with an ultrahigh thermal conductivity. In comparison, h-BN is a high-thermal conductivity electrical insulator, which is more suitable than metals for a number of applications in thermal management of electronic devices. Continuous and porous foam structures of both graphitic carbon and h-BN have been synthesized for thermal management and other applications. High-thermal conductivity and light-weight graphite foams have demonstrated superior thermal performance than both metal foams and van der Waals bonded networks of carbon nanotubes and graphitic flakes. However, the volume fraction and effective thermal conductivity of existing h-BN foam structures are still limited by the large pore size and limited specific surface area of the sacrificial reticular nickel foam templates used for chemical vapor deposition (CVD) of h-BN. This thesis reports on an investigation of the use of sacrificial sintered nickel powder templates with reduced pore sizes to increase the surface area of h-BN foam grown by atmospheric pressure CVD (APCVD) on the template. The volume fraction of the obtained h-BN foam is increased by a factor of 2.8 compared to a baseline h-BN foam grown on a commercial reticular nickel foam template. With poly(methyl methacrylate) (PMMA) filled into the pore space of the h-BN foam, the room-temperature effective thermal conductivity of the composite increases from 0.31 ± 0.02 Wm⁻¹K⁻¹ for the baseline structure to 0.51 ± 0.04 Wm⁻¹K⁻¹ for the structure with increased h-BN volume fraction. The room-temperature solid thermal conductivity of the h-BN strut is determined from the effective thermal conductivity via the Lemlich model to be 380 ± 80 Wm⁻¹K⁻¹, which is comparable to literature basal-plane values for h-BN crystals and compressed pellets. For a h-BN foam structure annealed at 700°C upon growth for 48 hrs, the solid thermal conductivity is 490 ± 120Wm⁻¹K⁻¹

description: The increasingly personal and ubiquitous capabilities of computing—everything from smartphones to virtual reality—are enabling us to build a brave new world in the digital realm. Despite these advances in the virtual world, our ability as end-users to transform the physical world still remains limited. The emergence of low-cost fabrication technology (most notably 3D printing) has brought us a dawn of making, promising to empower everyday users with the ability to fabricate physical objects of their own design. However, the technology itself is oblivious of the physical world—things are, in most cases, assumed to be printed from scratch in isolation from the real world objects they will be attached to and work with. To bridge this ‘gulf of fabrication’, my thesis research focuses on developing fabrication techniques with design tool integration to enable users to expressively create designs that can be attached to and function with existing real-world objects. Specifically, my work explores techniques that leverage the 3D printing process to create attachments directly over, onto and around existing objects; a design tool further enables people to specify and generate adaptations that can be attached to and mechanically transform existing objects in user-customized ways; a user-driven approach allows people to express and iterate structures that are optimized to support existing objects; finally, a library of ‘embeddables’ demonstrate that existing objects can also augment 3D printed designs by embedding a large variety of material to realize different properties and functionalities. Overall my thesis aspires to make fabrication real—enabling people to express, iterate and fabricate their designs that closely work with real-world objects to augment one another.

Thermal theory of aluminum particle ignition in continuum, free-molecular, and transition heat transfer regimes

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Most studies on nano- and micro- sized aluminum particle ignition have been focused on the processes occuring inside particles. In the current paper, thermal ignition of an aluminum particle in the air is simulated with different heat transfer models: continuum, free-molecular and Fuchs model. A single parabolic oxidation law is assumed in the particle size range from nano- to millimeter diameters. A particle is considered ignited when it reaches the oxide melting point. The criterion defining the limits of validity for each model is the ratio of continuum and free-molecular heat transfer rates. The dependence of ignition temperature $T_i$ on particle size is in a qualitative agreement with the experimental trends: $T_i$ can have values in the range 700--1500 K for nanoparticles due to the dominating contribution of a free-molecular heat transfer, and sharp growth of $T_i$ with the particle size in the range of 1-100 $μ$m diameter is due to the transitional character of heat transfer. For small values of accommodation coefficient, ignition may occur in the critical ignition mode with the thermal runaway. The results suggest the importance of heat transfer and, in particular, energy accommodation in ignition of nano- and micro- sized particles.

description: We present the results of a study of the globular cluster systems of 6 massive spiral galaxies, originally cataloged as low surface brightness galaxies but here shown to span a wide range of central surface brightness values, including two intermediate to low surface brightness galaxies. We used the Advanced Camera for Surveys on board HST to obtain photometry in the F475W and F775W bands and select sources with photometric and morphological properties consistent with those of globular clusters. A total of 206 candidates were identified in our target galaxies. From a direct comparison with the Galactic globular cluster system we derive specific frequency values for each galaxy that are in the expected range for late-type galaxies. We show that the globular cluster candidates in all galaxies have properties consistent with globular cluster systems of previously studied galaxies in terms of luminosity, sizes and color. We establish the presence of globular clusters in the two intermediate to low surface brightness galaxies in our sample and show that their properties do not have any significant deviation from the behavior observed in the other sample galaxies. Our results are broadly consistent with a scenario in which low surface brightness galaxies follow roughly the same evolutionary history as normal (i.e. high surface) brightness galaxies except at a much lower rate, but require the presence of an initial period of star formation intense enough to allow the formation of massive star clusters.

description: We evaluate long-distance electromagnetic (QED) contributions to $\bar{B}{}^0 \to D^+ τ^{-} \barν_τ$ and $B^- \to D^0 τ^{-} \barν_τ$ relative to $\bar{B}{}^0 \to D^+ μ^{-} \barν_μ$ and $B^- \to D^0 μ^{-} \barν_μ$, respectively, in the standard model. We point out that the QED corrections to the ratios $R(D^{+})$ and $R(D^{0})$ are not negligible, contrary to the expectation that radiative corrections are almost canceled out in the ratio of the two branching fractions. The reason is that long-distance QED corrections depend on the masses and relative velocities of the daughter particles. We find that theoretical predictions for $R(D^{+})^{τ/μ}$ and $R(D^{0})^{τ/μ}$ can be amplified by $\sim4\%$ and $\sim3\%$, respectively, for the soft-photon energy cut in range $20$-$40$ MeV.

description: This paper assesses the extent to which German import competition has contributed to the observed differential decline in manufacturing employment across French regions. The study employs an exposure research design that exploits differences in regional manufacturing specialisation across French départements combined with an instrumental variable strategy. The analysis does not establish a connection between German import competition and differential changes in regional French manufacturing employment. This result suggests that German import competition has neither driven nor halted the overall decline of French manufacturing employment. It also indicates that the sizeable and long-lasting negative regional employment effects of trade between China and developed countries do not necessarily generalise.

description: The dynamics of a few ultra-cold bosons tunneling from a one-dimensional potential well into open space is studied. In such a system several decay channels can be distinguished, each corresponding to a different number of bosons escaping simultaneously. We show that as the interparticle interaction strength is changed, the system undergoes transitions between distinct regimes characterized by the dominance of different decay channels. These transitions are reflected in the behavior of the decay rate of the system, which is measurable experimentally. By means of a simple theoretical description we show that the transitions occur at the points where a new decay channel becomes energetically viable. The results provide insight into the behavior of decaying few-body systems and may have potential interest to experiments.

description: We explore the constraints on dark sector models imposed by the recent observation of coincident gravitational waves and gamma rays from a binary neutron star merger, GW170817. Rather than focusing on specific models as has been considered by other authors, we explore this in the context of the equation of state approach of which the specific models are special cases. After confirming the strong constraints found by others for Horndeski, Einstein-Aether and massive gravity models, we discuss how it is possible to construct models which might evade the constraints from GW170817 but still leading to cosmologically interesting modifications to gravity. Possible examples are ``miracle cancellations" such as in $f(R)$ models, nonlocal models and higher-order derivatives. The latter two rely on the dimensionless ratio of the wave number of the observed gravitational waves to the Hubble expansion rate being very large ($\sim10^{19}$) which is used to suppress modifications to the speed of gravitational waves.

Quantum Field Theory With No Zero-Point Energy

Year: 2018
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Traditional quantum field theory can lead to enormous zero-point energy, which markedly disagrees with experiment. Unfortunately, this situation is built into conventional canonical quantization procedures. For identical classical theories, an alternative quantization procedure, called affine field quantization, leads to the desirable feature of having a vanishing zero-point energy. This procedure has been applied to renormalizable and nonrenormalizable covariant scalar fields, fermion fields, as well as general relativity. Simpler models are offered as an introduction to affine field quantization.

Discovery

User Experience

description: In 2017, the German federal state of Hamburg decided to fund a development plan for Open Science, greatly supporting Openness in the local research landscape. It affects three types of users: researchers, their institutions and the general public. The Hamburg State and University Library carries out a project for building a central information hub, giving citizens, researchers and the media an overview of (open) science in Hamburg and a good starting point for further exploration and research. The project focusses on three main fields of activity: (meta-)data aggregation from repositories, research data management systems, and CRISes, providing a discovery system and the creation of useful edited content for the portal. While the task of building an aggregation and discovery service is not new, the presentation of local science aimed at a local public allows for a different presentation of the scientific data. Since our project endorses openness, almost all of our sourcecode is published on Github and can freely be used by other projects.

Dynamical properties of collective excitations in twisted bilayer Graphene

description: Employing the recently developed momentum-space quantum Monte Carlo scheme, we study the dynamic response of single-particle and collective excitations in realistic continuum models of twisted bilayer graphene. At charge neutrality, this unbiased numerical method reveals strong competition between different symmetry breaking channels with a leading instability towards the intervalley coherent state. Single-particle spectra indicate that repulsive interactions push the fermion spectral weight away from the Fermi energy and open up an insulating gap. The spectra of collective excitations suggest an approximate valley $SU(2)$ symmetry. At low-energy, long-lived valley waves are observed, which resemble spin waves of Heisenberg ferromagnetism. At high-energy, these sharp modes quickly become over-damped, when their energy reaches the fermion particle-hole continuum.

description: Cross-border alcohol shopping threatens health outcomes and tax revenue, yet offers potential jobs and investment for the Baltic border regions. Exploiting the COVID-19-induced border closures in 2020 with an event study, and several large tax changes using differences-in-differences, this paper measures beer purchases in border regions of the Baltic States. Using monthly data from the Carlsberg group, beer sales in lower tax border regions dropped sharply during the COVID-19 closures, while sales increased modestly in higher tax border areas. Evidence from tax changes in Lithuania and Estonia also suggests dramatic effects on sales in lower tax Latvian border districts.
Separating baryons and dark matter in cluster cores: a full 2-D lensing and dynamic analysis of Abell 383 and MS2137-23

description: (abridged) We utilize existing imaging and spectroscopic data for the galaxy clusters MS2137-23 and Abell 383 to present improved measures of the distribution of dark and baryonic material in the clusters' central regions. Our method, based on the combination of gravitational lensing and dynamical data, is uniquely capable of separating the distribution of dark and baryonic components at scales below 100 kpc. We find a variety of strong lensing models fit the available data, including some with dark matter profiles as steep as expected from recent simulations. However, when combined with stellar velocity dispersion data for the brightest member, shallower inner slopes than predicted by numerical simulations are preferred. For Abell 383, the preferred shallow inner slopes are statistically a good fit only when the multiple image position uncertainties associated with our lens model are assumed to be 0\farcs5, to account for unknown substructure. No statistically satisfactory fit was obtained matching both the multiple image lensing data and the velocity dispersion profile of the brightest cluster galaxy in MS2137-23. This suggests that the mass model we are using, which comprises a pseudo-elliptical generalized NFW profile and a brightest cluster galaxy component may inadequately represent the inner cluster regions. This may plausibly arise due to halo triaxiality or by the gravitational interaction of baryons and dark matter in cluster cores. However, the progress made via this detailed study highlights the key role that complementary observations of lensed features and stellar dynamics offer in understanding the interaction between dark and baryonic matter on non-linear scales in the central regions of clusters.

Loop Variables and the Virasoro Group

description: We derive an expression in closed form for the action of a finite element of the Virasoro Group on generalized vertex operators. This complements earlier results giving an algorithm to compute the action of a finite string of generators of the Virasoro Algebra on generalized vertex operators. The main new idea is to use a first order formalism to represent the infinitesimal group element as a loop variable. To obtain a finite group element it is necessary to thicken the loop to a band of finite thickness. This technique makes the calculation very simple.

Machine Learning Techniques in Applied Econometrics

description: The main focus in econometrics is to provide an explanation of various observed outcomes. Structural econometricians obtain reliable estimates of parameters that describe an economic system to provide an understanding of the underlying processes that determine equilibrium outcomes. The estimation process is based on conditions implied by economic theory. On the other hand, the main focus in machine learning is to provide accurate predictions of the variables of interest. While these techniques are extremely powerful for forecasting, it can be very hard to interpret the underlying structure implied by them. As machine learning techniques become more popular and computers become capable of storing and processing large quantities of data, there have been some recent e orts to incorporate such techniques into structural econometric models. My research aims to extend this literature. In my thesis I investigate whether it is possible to incorporate machine learning techniques in econometric models in a meaningful way. I explore two different approaches for doing so - first, I generalize the idea of regularization from machine learning to the Generalized Method of Moments framework; second, I apply pre-existing classification techniques from machine learning to the Propensity Score framework. Finally, I employ the empirical techniques developed in the second chapter to address a public policy question { that of the effectiveness of India's Safe Motherhood Scheme.
QCD corrections to the charged Higgs decay of a heavy quark

description: We present an analytic formula for the $O(α_s)$ corrections to the decay $t\to H^+b$ for nonzero $m_H$ and $m_b$. The Equivalence Theorem is used to relate these corrections to those for the process $t\to W^+b$. Contrary to previously published results we find that the effect of the $b$ quark mass is negligible for a wide range of $m_t$, $m_H$ and $\tan β$.
