description: We study the quantum stability of the dynamics of ions in a Paul trap. We revisit the results of Wang et al. [Phys. Rev. A 52, 1419 (1995)], which showed that quantum trajectories did not have the same region of stability as their classical counterpart, contrary to what is obtained from a Floquet analysis of the motion in the periodic trapping field. Using numerical simulations of the full wave-packet dynamics, we confirm that the classical trapping criterion are fully applicable to quantum motion, when considering both the expectation value of the position of the wave packet and its width.

A New Light Particle in B Decays?

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We investigate the possibility whether the tensions with SM expectations observed in several b -> sll transitions, including hints for lepton flavour non-universality, could be due to the decay of B into a new light resonance. We find that qualitative agreement with the data can be obtained with a light vector resonance dominantly decaying invisibly. This scenario predicts a shift in the muon anomalous magnetic moment that could explain the long-standing discrepancy. The most stringent constraint comes from searches for B decays with missing energy. A striking prediction is a strong q^2 dependence of the lepton flavour universality ratios R_K and R_K* that should allow to clearly confirm or rule out this possibility experimentally. We also comment on the possible connection of the invisible decay product with Dark Matter.

description: This SWAT+ modelling protocol was designed for guiding model setup development and model calibration in 14 European case study sites participating in the modelling component of the EU funded research and innovation project OPtimal strategies to retAIN and re-use water and nutrients in small agricultural catchments across different soil-climatic regions in Europe (OPTAIN). These 14 case studies are small agricultural catchments (ranging in size from 21 to 254 km2 ) located in three biogeographical regions of Europe and 12 different countries. The main topic of OPTAIN are Natural/Small Water Retention Measures, which are a relatively new concept. These are small and multi-functional measures for the retention/management of water and nutrients in the landscape, thus addressing drought/flood control, management of water quality problems, climate change adaptation, biodiversity restoration, etc.

description: Background: Schizophrenia is a serious public health problem that affects ∼1% of the US population. Aims: To examine treatment patterns and evaluate healthcare resource utilization (HRU) and costs among young adults (18–35 years) with schizophrenia who were early in the disease. Materials and methods: Patients aged 18–64 years with ≥2 schizophrenia diagnoses in the identification period (January 1, 2012–September 30, 2015) and continuous enrollment for ≥12 months pre- and post-index date were identified from the OptumInsight Clinformatics DataMart. Demographics, clinical characteristics, HRU, costs, and treatment patterns were compared between schizophrenia and non-schizophrenia “controls” cohorts and between young (18–35 years) and older adults (36–64 years) with schizophrenia. Results: Among 9,889 schizophrenia patients, 23.70% were young adults (aged 18–35), had higher all-cause per-patient-per-year (PPPY) costs ($22,338 vs $7,332; p p p p p  Limitations: Claims data are collected for payment and not research. The presence of a prescription claim does not indicate medication was consumed or taken as prescribed. Conclusions: The economic burden for schizophrenia patients is substantial, especially among young adults. Based on this analysis, further research is warranted to better understand the association between adherent treatment patterns earlier in the disease and long-term health outcomes among patients with schizophrenia.

description: We investigate the impact of the local spin texture on the differential conductance by scanning tunneling microscopy. In the focus is the previously found non-collinear magnetoresistance, which originates from spin mixing effects upon electron hopping between adjacent sites with canted magnetic moments. In the present work it is studied with lateral resolution both for the zero magnetic field spin spiral state as well as for individual magnetic skyrmions at different magnetic field values. We analyze in detail the response of the differential conductance and find different dependencies of peak energy and peak intensity on the local properties of the non-collinear spin texture. We find that in the center of a skyrmion the peak energy and intensity scale roughly linear with the angle between nearest neighbor moments. Elsewhere in the skyrmion, where the non-collinearity is not isotropic and the magnetization quantization axis varies, the behavior of the peak energy is more complex.

description: Compared to the well-studied topic of human mobility in real geographic space, very few studies focus on human mobility in virtual space, such as interests, knowledge, ideas, and so forth. However, it relates to the issues of management of public opinions, knowledge diffusion, and innovation. In this paper, we assume that the interests of a group of online users can span a Euclidean space which is called interest space, and the transfers of user interests can be modeled as the Levy Flight on the interest space. To consider the interaction between users, we assume that the random walkers are not independent but interact each other indirectly via the digital resources in the interest space. The model can successfully reproduce a set of scaling laws for describing the growth of the attention flow networks of real online communities, and the ranges of the exponents of the scaling are similar with the empirical data. Further, we can infer parameters for describing the individual behaviors of the users according to the scaling laws of the empirical attention flow network. Our model can not only provide theoretical understanding on human online behaviors, but also has wide potential applications, such as dissemination and management of public opinions, online recommendation, etc.
Formalism of optical coherency in material media with a quantum mechanical treatment

description: The fluctuations or disordered motion of the electromagnetic fields are described by statistical properties rather than instantaneous values. This statistical description of the optical fields is underlying in the Stokes-Mueller formalism that applies to measurable intensities. However, the fundamental concept of optical coherence, that is assessed by the ability of waves to interfere, is not treatable by this formalism because it omits the global phase. In this work we show that, using an analogy between deterministic matrix states associated to optical media and quantum mechanical wavefunctions, it is possible to construct a general formalism that accounts for the additional terms resulting from the coherency effects that average out for incoherent treatments. This method generalizes further the concept of coherent superposition to describe how deterministic states of optical media can superpose to generate another deterministic media state. Our formalism of coherency is used to study the combined polarimetric response of interfering plasmonic nanoantennas.

description: In this paper we study the spectral heat content for various Lévy processes. We establish the asymptotic behavior of the spectral heat content for Lévy processes of bounded variation in $\mathbb{R}^{d}$, $d\geq 1$. We also study the spectral heat content for arbitrary open sets of finite Lebesgue measure in $\mathbb{R}$ with respect to Lévy processes of unbounded variation under certain conditions on their characteristic exponents. Finally we establish that the asymptotic behavior of the spectral heat content is stable under integrable perturbations to the Lévy measure.

Inhomogeneous fluid of penetrable-spheres: application of the random phase approximation

Year: 2017
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The focus of the present work is the application of the random phase approximation (RPA), derived for inhomogeneous fluids [Frydel and Ma, Phys. Rev. E 93, 062112 (2016)], to penetrable-spheres. As penetrable-spheres transform into hard-spheres with increasing interactions, they provide an interesting case for exploring the RPA, its shortcomings, and limitations, the weak- versus the strong-coupling limit. Two scenarios taken up by the present study are a one-component and a two-component fluid with symmetric interactions. In the latter case, the mean-field contributions cancel out and any contributions from particle interactions are accounted for by correlations. The accuracy of the RPA for this case is the result of a somewhat lucky cancellation of errors.

description: Structural characterization of metalloporphyrins in complex systems such as native hydrocarbons is in the focus of scientific and industrial interests since many years. We describe electron-nuclear double resonance (ENDOR) of crude oil from the well without any additional sample treatment (i.e., in the native environment) in the magnetic field of about 3.4 T and temperature of 50 K by applying microwave pulses at 94 GHz (W-band) and radiofrequency pulses at near the proton Larmor frequencies of 144 MHz to probe the paramagnetic vanadyls. By means of density functional theory (DFT) calculations, ENDOR features are explained and ascribed to certain vanadyl porhyrin structural forms known to be present in crude oil.

description: We record an observation about the Witten indices in two families of gauged linear sigma models: the U(2) model for linear sections of Grassmannians, and the U(1) model for quadric complete intersections. We describe how the Witten indices are related to the Euler characteristics of the singular skew-symmetric or symmetric determinantal varieties featuring in the analysis of their opposite phases, and we discuss the extent to which these relationships can be reconciled with standard Born-Oppenheimer arguments.

Correlation-induced superconductivity dynamically stabilized and enhanced by laser irradiation

description: Studies on out-of-equilibrium dynamics have paved a way to realize a new state of matter. Especially, superconductor-like properties above room temperatures recently suggested in copper oxides achieved by selectively exciting vibrational phonon modes by laser have inspired studies on an alternative and general strategy to be pursued for high temperature superconductivity. Here, we show that the superconductivity can be enhanced by irradiating laser to correlated electron systems owing to two mechanisms: First, the effective attractive interaction of carriers is enhanced by the dynamical localization mechanism, which drives the system into strong coupling regions. Secondly, the irradiation allows reaching uniform and enhanced superconductivity dynamically stabilized without deteriorating into equilibrium inhomogeneities that suppress superconductivity. The dynamical superconductivity is subject to the Higgs oscillations during and after the irradiation. Our finding shed light on a way to enhance superconductivity that is inaccessible in equilibrium in strongly correlated electron systems.

description: Shotgun metagenomics sequencing experiments are now finding a wide range of applications, nonetheless there are still limited guidelines regarding the depth of sequencing needed to acquire meaningful information, especially regarding antimicrobial resistance genes (ARGs) identification. In this study, we explored these issues by sequencing 4 human plaque samples and 1 Microbial Community Standard, and by generating in silico a total of 40 sequences datasets simulating a variety of sequencing depth. All datasets underwent quality controls including adapter and quality trimming, and host DNA contamination removal. Once a good-quality microbial sequences dataset was obtained, a quantitative profiling of microbial communities composition was carried out and ARGs presence was assessed. When investigating the impact of sequencing depth on quantitative taxonomic profiling in the Microbial Community Standard datasets, we found some discrepancies in the identified microbial species and their abundances when compared to the reported ones. Such differences are however consistent across different sequencing depth, suggesting that they are instead linked to limits of the taxonomic profiling methods. Overall, results showed that sequencing depth has a great impact on metagenomic samples both at qualitative (i.e. presence/absence) and quantitative level in terms of loss of information, especially in datasets having <35 millions of reads. The presence of ARGs was also assessed: overall, a total of 133 ARGs were identified and 23% of them did not consistently result as present or absent across different sequencing depth datasets of the same sample. In particular, we observed that the information loss increased at diminishing sequencing depth, with more than half of such genes lost at <20 million of reads. In conclusion, samples with reduced sequencing depths decrease resolution for microbiome qualitative and quantitative profiling and hinder ARGs identification. This study highlights the importance of carefully considering such aspects in designing shotgun metagenomics experiments to maximize microbiome analyses.

description: We present a detailed study of an earth-directed coronal mass ejection (Full halo CME) event happened on 2011 February 15 making use of white light observations by three coronagraphs and radio observations by Wind/WAVES. We applied three different methods to reconstruct the propagation direction and traveling distance of the CME and its driven shock. We measured the kinematics of the CME leading edge from white light images observed by STEREO A and B, tracked the CME-driven shock using the frequency drift observed by Wind/WAVES together with an interplanetary density model, and obtained the equivalent scattering centers of the CME by Polarization Ratio(PR) method. For the first time, we applied PR method to different features distinguished from LASCO/C2 polarimetric observations and calculated their projections onto white light images observed by STEREO A and B. By combining the graduated cylindrical shell (GCS) forward modeling with the PR method, we proposed a new GCS-PR method to derive 3D parameters of a CME observed from a single perspective at Earth. Comparisons between different methods show a good degree of consistence in the derived 3D results.

description: The Carina nebula hosts a large number of globulettes. The majority are of planetary mass, but there are also those with masses of several tens up to a few hundred Jupiter masses. We carried out radio observations of molecular line emission in 12CO and 13CO (2-1) and (3-2) of 12 larger objects in addition of positions in adjacent shell structures using APEX. All selected objects were detected with radial velocities shifted relative to the emission from related shell structures and background molecular clouds. Globulettes along the western part of an extended dust shell show a small spread in velocity with small velocity shifts relative to the shell. This system of globulettes and shell structures in the foreground of the bright nebulosity surrounding the cluster Trumpler 14 is expanding with a few km/s relative to the cluster. The Carina globulettes are compact and denser than objects of similar mass studied previously in the Rosette nebula. Some globulettes in Tr 14 are located far from any shell structures. These objects move at a similar speed as the globulettes along the shell. The distribution and velocities of the globulettes studied suggest that they have originated from eroding shells and elephant trunks.

description: Magnetic fields in the sun's outer atmosphere -- the corona -- control both solar-wind acceleration and the dynamics of solar eruptions. We present the first clear observational evidence of coronal magnetic nulls in off-limb linearly polarized observations of pseudostreamers, taken by the Coronal Multichannel Polarimeter (CoMP) telescope. These nulls represent regions where magnetic reconnection is likely to act as a catalyst for solar activity. CoMP linear-polarization observations also provide an independent, coronal proxy for magnetic expansion into the solar wind, a quantity often used to parameterize and predict the solar wind speed at Earth. We introduce a new method for explicitly calculating expansion factors from CoMP coronal linear-polarization observations, which does not require photospheric extrapolations. We conclude that linearly-polarized light is a powerful new diagnostic of critical coronal magnetic topologies and the expanding magnetic flux tubes that channel the solar wind.

description: We develop methods to efficiently reconstruct the topology and line parameters of a power grid from the measurement of nodal variables. We propose two compressed sensing algorithms that minimize the amount of necessary measurement resources by exploiting network sparsity, symmetry of connections and potential prior knowledge about the connectivity. The algorithms are reciprocal to established state estimation methods, where nodal variables are estimated from few measurements given the network structure. Hence, they enable an advanced grid monitoring where both state and structure of a grid are subject to uncertainties or missing information.

description: Titanium Oxynitride (TiOxNy) thin films are fabricated using reactive magnetron sputtering. The mechanism of their growth formation is explained and their optical properties are presented. The films grown when the level of residual Oxygen in the background vacuum was between 5E-9Torr to 20E-9Torr exhibit double Epsilon-Near-Zero (2-ENZ) behaviour with ENZ1 and ENZ2 wavelengths tunable in the 700-850 nm and in the 1100-1350 nm spectral ranges, respectively. Samples fabricated when the level of residual Oxygen in the background vacuum was above 2E-8Torr exhibit non-metallic behaviour, while the layers deposited when the level of residual Oxygen in the background vacuum was below 5E-9Torr, show metallic behaviour with a single ENZ value. The double ENZ phenomenon is related to the level of residual Oxygen in the background vacuum and is attributed to the mixture of TiN and TiOxNy/TiOx phases in the films. Varying the partial pressure of nitrogen during the deposition can further control the amount of TiN, TiOx and TiOxNy compounds in the films and, therefore, tune the screened plasma wavelength. A good approximation of the ellipsometric behaviour is achieved with Maxwell-Garnett theory for a composite film formed by a mixture of TiO2 and TiN phases suggesting that double ENZ TiOxNy films are formed by inclusions of TiN within a TiO2 matrix. These oxynitride compounds could be considered as new materials exhibiting double ENZ in the visible and near-IR spectral ranges.

description: This study explores the intersecting factors contributing to violence against women in Pakistan as depicted in contemporary literary works by women writers. Drawing upon Johan Galtung’s typology of violence, we aim to examine the dynamics of direct, structural, and cultural violence within Fatima Bhutto’s The Shadow of the Crescent Moon (2013). The novel is particularly suited for this analysis as it delves into the lives of Pakistani people amidst war, political turmoil, and societal repression. We argue that Bhutto’s novel underscores the cyclical perpetuation of oppression and the reinforcement of societal norms. This is achieved by illustrating how violence is perpetrated across micro, meso, and macro dimensions, and how intersecting identities shape women’s experiences of violence. Through the experiences of female characters like Mina and Samarra, the novel elucidates the complexities of violence by expanding its scope beyond physical abuse to encompass psychological trauma, societal discrimination, and political exploitation. Moreover, the interplay between cultural norms, structural inequalities, and violence against women is reflected in how direct violence—ranging from physical abuse to sexual assault—permeates the lives of female characters and is normalized and justified by the insidious nature of cultural and structural violence.

description: In this paper, the free-molecular flow of nitrogen in Holweck pump is investigated. The aim of the study is to rationalize the geometrical characteristics of the pump to achieve the maximum compression ratio. An optimisation algorithm is proposed. The developed numerical design methods allow reducing the required number of full-scale experiments. This leads to the possibility of reducing the design time of the pump and improving its performance due to the possibility of varying different parameters.

description: Hybrid superconductor-semiconducting nanowire devices provide an ideal platform to investigating novel intragap bound states, such as the Andreev bound states (ABSs), Yu-Shiba-Rusinov (YSR) states, and the Majorana bound states. The competition between Kondo correlations and superconductivity in Josephson quantum dot (QD) devices results in two different ground states and the occurrence of a 0-$π$ quantum phase transition. Here we report on transport measurements on hybrid superconductor-InSb nanowire QD devices with different device geometries. We demonstrate a realization of continuous gate-tunable ABSs with both 0-type levels and $π$-type levels. This allow us to manipulate the transition between 0 and $π$ junction and explore charge transport and spectrum in the vicinity of the quantum phase transition regime. Furthermore, we find a coexistence of 0-type ABS and $π$-type ABS in the same charge state. By measuring temperature and magnetic field evolution of the ABSs, the different natures of the two sets of ABSs are verified, being consistent with the scenario of phase transition between the singlet and doublet ground state. Our study provides insights into Andreev transport properties of hybrid superconductor-QD devices and sheds light on the crossover behavior of the subgap spectrum in the vicinity of 0-$π$ transition.

Possible Triplet Superconducting Order in Magnetic Superconducting Phase induced by Paramagnetic Pair-Breaking

description: Motivated by recent thermal conductivity measurements in the superconductor CeCoIn5, we theoretically examine a possible staggered spin-triplet superconducting order to be induced by the coupled spin-density-wave (SDW) and d-wave superconducting (SC) orders in the high field and low temperature (HFLT) SC phase peculiar to this material with strong paramagnetic pair-breaking (PPB). It is shown that one type of the $π$-triplet order is consistent with the thermal conductivity data and can naturally be incorporated in the picture that the Q-phase is a consequence of the strong PPB effect inducing the SDW order and the FFLO spatial modulation parallel to the applied magnetic field.

Entropy, gap and a multi-parameter deformation of the Fredkin spin chain

description: We introduce a multi-parameter deformation of the Fredkin spin $1/2$ chain whose ground state is a weighted superposition of Dyck paths, depending on a set of parameters $t_i$ along the chain. The parameters are introduced in such a way to maintain the system frustration-free while allowing to explore a range of possible phases. In the case where the parameters are uniform, and a color degree of freedom is added we establish a phase diagram with a transition between an area law and a volume low. The volume entropy obtained for half a chain is $n \log s$ where $n$ is the half-chain length and $s$ is the number of colors. Next, we prove an upper bound on the spectral gap of the $t>1, s>1$ phase, scaling as $Δ=O((4s)^nt^{-n^2/2})$, similar to a recent a result about the deformed Motzkin model, albeit derived in a different way. Finally, using an additional variational argument we prove an exponential lower bound on the gap of the model for $t>1, s=1$, which provides an example of a system with bounded entanglement entropy and a vanishing spectral gap.

Tritium ions in KATRIN: blocking, removal and detection

description: The KArlsruhe TRItium Neutrino  (KATRIN) experiment aims at the model-independent determination of the absolute neutrino mass scale. 
For this purpose, KATRIN investigates the imprint of the neutrino mass on the tritium beta spectrum near its kinematic end point.
KATRIN employs a high-luminosity Windowless Gaseous Tritium Source (WGTS), which creates $10^{11}$ beta electrons per second.
The beta electrons are guided by a strong magnetic field up to 6 T to the Main spectrometer, which acts as a high-pass MAC-E filter.

Inadvertently, tritium ions are created from the source gas by tritium beta decay and inelastic scattering of beta electrons.
Under nominal conditions, $2\cdot 10^{11}$ positive ions/s leave the WGTS along the magnetic guiding field towards the spectrometers.
There, they could create background due to the radioactivity of the tritium and via the ionisation of residual gas.
For this reason, the ion flux into the Pre-spectrometer (PS) has to be restricted to $1\cdot10^4$ ions/s.

Ring and dipole electrodes were therefore installed in the KATRIN beamline in order to block the positive tritium ions with electrostatic potentials and to remove the stored ions via $E\times B$ drift in negative dipole potentials.
A proof-of-principle for the ion blocking and removal was achieved in the First Light measurement campaign in 2016 with a pencil beam of non-radioactive deuterium ions.
Nevertheless, the ring electrode potentials could be neutralised during tritium operation due to the trapping of secondary electrons and negative ions in the positive potential wells.
For this reason, a constant monitoring of the ion flux into the PS was installed and used during the First Tritium measurements in May and June 2018 with about 0.5% of the nominal tritium concentration.
With regard to ion safety, an upper limit on the ion flux into the PS at the aspired level of $1\cdot 10^{4}$ ions/s could be derived via the ionisation of residual gas in the PS.
During the first scans of the tritium beta spectrum with KATRIN, a current measurement in the PS monitored the ion flux into the PS continuously.
In the meantime, a current measurement at the one dipole electrode closest to the source measured only about 50% of the expected ion flux, while the other dipole electrodes observed no ions at all.
Such inadvertent ion blocking had already been observed during First Light and is attributed to work function differences of different beam tube materials.
Whether the inadvertent ion blocking also occurs during measurements with 100% tritium and how the trapped ions might affect the neutrino mass measurements needs to be subject of future investigations.
