description: Heisenberg-type spin models in the limit of a low number of excitations are useful tools to study basic mechanisms in strongly correlated and magnetic systems. Many of these mechanisms can be experimentally tested using ultracold atoms. Here, we discuss the implementation of a quantum state transfer protocol in a tight-binding chain in the presence of an inhomogeneous external potential. We show that it can be used to extend the parameter range in which high fidelity state transfer can be achieved beyond the well established weak-coupling regime. Among the class of mirror-reflecting potentials that allow for high-fidelity quantum state transfer, the harmonic case is especially relevant because it allows us to formulate a proposal for the experimental implementation of the protocol in the context of optical lattices.

description: Studien konnten zeigen, dass das Geschlecht von PatientInnen medizinische Entscheidungsprozesse in ärztlichen Konsultationen beeinflusst. Wenig im Fokus stand jedoch bisher, wie Geschlecht in medizinischen Settings produziert und konstruiert wird. Diese Pilotstudie hat die Geschlechterkonstruktionen von niedergelassenen ÄrztInnen in ihren Erzählungen zur Empfehlung des Nahrungsergänzungsmittels Selen an KrebspatientInnen untersucht. Es wurden zwei Fokusgruppendiskussionen durchgeführt und mit Elementen der dokumentarischen Methode sowie mittels qualitativer Inhaltsanalyse ausgewertet. Die ÄrztInnen stellten ‚Geschlecht‘ als einen spezifischen, auf der PatientInnenseite lokalisierten Komplex von Verhalten und Befinden dar, wobei Männer als zu rigide und simplizistisch und Frauen als naiv und zu emotional geschildert wurden. Ihre Empfehlung von Selen sahen ÄrztInnen als Versuch, als problematisch empfundene geschlechtsspezifische Verhaltensweisen abzuschwächen.
Profits by Any Other Name: A Study of Domestic Profit Motivation in Relation to Mayoral Assassinations in Mexico

description: Assassinations of mayors, ex-mayors, and candidates for the office of mayor have been dramatically increasing in the Country of Mexico since the start of the Cartel Wars in 2006. The increased fragmentation and stress certain security initiatives have put on organized crime has caused cartels to reconsider the way in which they interact with domestic actors and communities. The objective of this paper is to determine if there is evidence of a relationship between mayoral assassination rates and Federal entities (states) with high numbers of select lootable resources. This theft could take the form of one or all activities related to resource exploitation such as direct theft for use, direct theft for black market sale, and extortion. The paper accomplishes this goal through a series of zero-inflated binomial regressions as well as other modeling methods in order to ensure the robustness of results. This paper finds evidence connecting mayoral assassinations to states with high profits from avocado growth and high numbers of illegal gas pipeline taps. This study fails to find a relationship between lootable mining resources and mayoral assassinations. This study also shows that previously thought to be salient factors connected to political assassinations in Mexico, such as political pluralization and the number of cartels active in an area, may not be as salient when it comes to determining mayoral assassinations. Overall, this study finds that some natural resource factors play a role in determining where cartels will choose to enact political violence at the local level.

description: Momentum and spin represent fundamental dynamical properties of quantum particles and fields. In particular, propagating optical waves (photons) carry momentum and longitudinal spin determined by the wave vector and circular polarization, respectively. Here we show that exactly the opposite can be the case for evanescent optical waves. A single evanescent wave possesses a spin component, which is independent of the polarization and is orthogonal to the wave vector. Furthermore, such a wave carries a momentum component, which is determined by the circular polarization and is also orthogonal to the wave vector. We show that these extraordinary properties reveal a fundamental Belinfante's spin momentum, known in field theory and unobservable in propagating fields. We demonstrate that the transverse momentum and spin push and twist a probe Mie particle in an evanescent field. This allows the observation of `impossible' properties of light and of a fundamental field-theory quantity, which was previously considered as `virtual'.

description: MOdified Newtonian dynamics (MOND) represents a phenomenological alternative to dark matter (DM) for the missing mass problem in galaxies and clusters of galaxies. We analyze the central regions of a local sample of $\sim 220$ early-type galaxies from the $\rm ATLAS^{3D}$ survey, to see if the data can be reproduced without recourse to DM. We estimate dynamical masses in the MOND context through Jeans analysis, and compare to $\rm ATLAS^{3D}$ stellar masses from stellar population synthesis. We find that the observed stellar mass--velocity dispersion relation is steeper than expected assuming MOND with a fixed stellar initial mass function (IMF) and a standard value for the acceleration parameter $a_{\rm 0}$. Turning from the space of observables to model space, a) fixing the IMF, a universal value for $a_{\rm 0}$ cannot be fitted, while, b) fixing $a_{\rm 0}$ and leaving the IMF free to vary, we find that it is "lighter" (Chabrier-like) for low-dispersion galaxies, and "heavier" (Salpeter-like) for high dispersions. This MOND-based trend matches inferences from Newtonian dynamics with DM, and from detailed analysis of spectral absorption lines, adding to the converging lines of evidence for a systematically-varying IMF.

description: A consistent set of asymptotic conditions for higher spin gravity in three dimensions is proposed in the case of vanishing cosmological constant. The asymptotic symmetries are found to be spanned by a higher spin extension of the BMS3 algebra with an appropriate central extension. It is also shown that our results can be recovered from the ones recently found for asymptotically AdS3 spacetimes by virtue of a suitable gauge choice that allows to perform the vanishing cosmological constant limit.

description: Motivated by the quest for an analogue of the Gromov-Hausdorff distance in noncommutative geometry which is well-behaved with respect to C*-algebraic structures, we propose a complete metric on the class of Leibniz quantum compact metric spaces, named the dual Gromov-Hausdorff propinquity. This metric resolves several important issues raised by recent research in noncommutative metric geometry: it makes *-isomorphism a necessary condition for distance zero, it is well-adapted to Leibniz seminorms, and --- very importantly --- is complete, unlike the quantum propinquity which we introduced earlier. Thus our new metric provides a natural tool for noncommutative metric geometry, designed to allow for the generalizations of techniques from metric geometry to C*-algebra theory.

description: We employ the closed-shell perturbed relativistic coupled-cluster (RCC) theory developed by us earlier [Phys. Rev. A {\bf 77}, 062516 (2008)] to evaluate the ground state static electric dipole polarizabilities (αs) of several atomic systems. In this work, we have incorporated a class of higher order many-body effects in our calculations that had not been taken into account in the above paper. We highlight their importance in improving the accuracy of $α$. We also calculate the ground state αs of the inert gas atoms and several iso-electronic singly and doubly charged ions in order to make a comparative study of the trends of the correlation effects. Furthermore, we have developed a method to construct intermediate diagrams that are required for the computation of the unperturbed singles and doubles coupled-cluster amplitudes. Our RCC results are compared with those of many-body perturbation theory at different orders to demonstrate the importance of higher order correlation effects for the accurate determination of (αs) of the systems that we have considered.

description: We numerically show that extreme events induced by parameter mismatches or noise in coupled oscillatory systems can be anticipated and suppressed before they actually occur. We show this in a main system unidirectionally coupled to an auxiliary system subject to a negative delayed feedback. Each system consists of two electronic oscillators coupled in a master-slave configuration. Extreme events are observed in this coupled system as large and sporadic desynchronization events. Under certain conditions, the auxiliary system can predict the dynamics of the main system. We use this to efficiently suppress the extreme events by applying a direct corrective reset to the main system.

description: We study the correlators of two circular Wilson loops of different radii at strong coupling. In our setup one Wilson loop is located inside the other. We use holography to calculate the connected two-point function. Both an AdS background and a confining background are considered. As the computation for the confining case cannot be carried out analytically we solve the problem numerically. In the AdS case our results agree with similar holographic calculations. In the case of a confining background we find an asymptotic area law, in agreement with the result of the lattice strong coupling expansion. We also elaborate on the subtle issue of the interplay between connected and disconnected string worldsheets.

Search for MeV dark photons in a light-shining-through-walls experiment at CERN

description: In addition to gravity, there might be another very weak interaction between the ordinary and dark matter transmitted by U'(1) gauge bosons A' (dark photons) mixing with our photons. If such A's exist, they could be searched for in a light-shining-through-a-wall experiment with a high energy electron beam. The electron energy absorption in a calorimeter (CAL1) is accompanied by the emission of bremsstrahlung A's in the reaction eZ -> eZA' of electrons scattering on nuclei due to the γ- A' mixing. A part of the primary beam energy is deposited in the CAL1, while the rest of the energy is transmitted by the A' through the "CAL1 wall" and deposited in another downstream calorimeter CAL2 by the e+e- pair from the A'->e+e- decay in flight. Thus, the A's could be observed by looking for an excess of events with the two-shower signature generated by a single high energy electron in the CAL1 and CAL2. A proposal to perform such an experiment to probe the still unexplored area of the mixing strength 10^{-5} < ε< 10^{-3} and masses M_{A'} < 100 MeV by using 10-300 GeV electron beams from the CERN SPS is presented. The experiment can provide complementary coverage of the parameter space, which is intended to be probed by other searches. It has also a capability for a sensitive search for A's decaying invisibly to dark-sector particles, such as dark matter, which could cover a significant part of the still allowed parameter space.

The signal is characterized by the presence of a single charged lepton from a W boson decay, jets, and missing transverse momentum. The analysis was performed using proton-proton collision data taken at a center-of-mass energy $\sqrt{s}$ = 13 TeV provided by the Large Hadron Collider and recorded by the ATLAS experiment, corresponding to 139 fb$^{-1}$. No statistically significant excess of events above the Standard Model expectation is found. Limits are set on the direct production of squarks and gluino in the simplified models, masses of up to 2.2 TeV (1.4 TeV) are excluded at 95% confidence level.
A Renormalizable Theory of Quantum Gravity: Renormalization Proof of the Gauge Theory of Volume Preserving Diffeomorphisms

description: Inertial and gravitational mass or energy-momentum need not be the same for virtual quantum states. Separating their roles naturally leads to the gauge theory of volume-preserving diffeomorphisms of an inner four-dimensional space. The gauge-fixed action and the path integral measure occurring in the generating functional for the quantum Green functions of the theory are shown to obey a BRST-type symmetry. The related Zinn-Justin-type equation restricting the corresponding quantum effective action is established. This equation limits the infinite parts of the quantum effective action to have the same form as the gauge-fixed Lagrangian of the theory proving its spacetime renormalizability. The inner space integrals occurring in the quantum effective action which are divergent due to the gauge group's infinite volume are shown to be regularizable in a way consistent with the symmetries of the theory demonstrating as a byproduct that viable quantum gauge field theories are not limited to finite-dimensional compact gauge groups as is commonly assumed.

description: We show that massive low energy particles traversing a branching zone or a crossing of quantum waveguides may experience a non standard trapping force that cannot be derived from a potential. For interacting cold Bose atoms we report on the formation of a localised Hartree ground state for three prototype waveguide geometries with broken translational symmetry: a cranked L-shaped waveguide L, a T-shaped waveguide T, and the crossing C of two quantum waveguides. The phenomenon is kinetic energy driven and cannot be described within the Thomas-Fermi approximation. Depending on the ratio of joining lateral tube diameters of the respective waveguides C,L,T delocalisation commences when the particle number N approaches a critical value. For the case of a binary mixture of two different Bose atom species A and B we observe non standard trapping of both atom species for subcritical particle numbers. A sudden demixing quantum transition takes place as the total particle number N=N_{A}+N_{B} is increased at fixed mixing ratio N_{A}/N_{B}. Depending on the mass ratio m_{A}/m_{B} the heavier atom species delocalises first for a wide range of interaction parameters. The numerical calculations are based on a splitting scheme involving an analytic approximation to the short time asymptotics of the imaginary time quantum propagator of a single particle obeying to Dirichlet boundary conditions at the walls inside the respective waveguides.

Two new figures (Fig.16, Fig.22) now elucidate differences between conservative trap potentials and non standard trapping in waveguides with broken translational symmetry.

description: Repair represents a more sustainable alternative to disposal as it maintains the functionality of products, whilst improving resource security and material efficiency. However, consumers may face a wide range of difficulties when making repair decisions due to uncertain residual life, the inconvenience and high cost of repair, concerns about access to information in repair manuals and service quality. Businesses are often considered responsible for these problems. This paper presents preliminary findings on how innovative business activities could resolve these issues and how business might benefit from these activities. Opportunities for, and challenges to, the adoption and execution of the activities are also discussed based on the practices of five businesses interviewed from three industries: furniture, textiles, electrical and electronic goods. The findings offer an insightful base for an upcoming study, with a larger sample, which will provide evidence for business stakeholders interested in developing commercial activities with a greater focus on product repairability and repair services as a form of business model innovation, and for policymakers to regulate and support commercial repair.

description: We present a self-consistent hydrodynamical simulation of a Milky Way-like galaxy, at the resolution of 0.05 pc. The model includes star formation and a new implementation of stellar feedback through photo-ionization, radiative pressure and supernovae. The simulation resolves the structure of the interstellar medium at subparsec resolution for a few cloud lifetimes, and at 0.05 pc for about a cloud crossing time. Turbulence cascade and gravitation from the kpc scales are de facto included in smaller structures like molecular clouds. We show that the formation of a bar influences the dynamics of the central ~100 pc by creating resonances. At larger radii, the spiral arms host the formation of regularly spaced clouds: beads on a string and spurs. These instabilities pump turbulent energy into the gas, generally in the supersonic regime. Because of asymmetric drift, the supernovae explode outside of their gaseous nursery, which diminishes the effect of feedback on the structure of clouds. The evolution of clouds is thus mostly due to fragmentation and gas consumption, regulated mainly by supersonic turbulence. The transition from turbulence supported to self-gravitating gas is detected in the gas density probability distribution function at ~2000 cm^-3. The power spectrum density suggests that gravitation governs the hierarchical organisation of structures from the galactic scale down to a few parsecs.

description: The results of a search for gluino and squark pair production pp decaying via charginos to a final state consisting of a W boson, the lightest neutralino, and quarks are presented. The signal is characterized by the presence of a single charged lepton from a W boson decay, jets, and missing transverse momentum. The analysis was performed using proton-proton collision data taken at a center-of-mass energy $\sqrt{s}$ = 13 TeV provided by the Large Hadron Collider and recorded by the ATLAS experiment, corresponding to 139 fb$^{-1}$. No statistically significant excess of events above the Standard Model expectation is found. Limits are set on the direct production of squarks and gluino in the simplified models, masses of up to 2.2 TeV (1.4 TeV) are excluded at 95% confidence level.

Charged Higgs contribution to $\bar{B}_s \rightarrow ϕπ^0 $ and $\bar{B}_s \rightarrow ϕρ^0 $

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

description: We study the decay modes $\bar{B}_s\to ϕπ^0$ and $\bar{B}_s\to ϕρ^0$ within the frameworks of two-Higgs doublet models type-II and typ-III. We adopt in our study Soft Collinear Effective Theory as a framework for the calculation of the amplitudes. We derive the contributions of the charged Higgs mediation to the weak effective Hamiltonian governing the decay processes in both models. Moreover we analyze the effect of the charged Higgs mediation on the Wilson coefficients of the electrowek penguins and on the branching ratios of $\bar{B}_s\to ϕπ^0$ and $\bar{B}_s\to ϕρ^0$ decays. We show that wthin two-Higgs doublet models type-II and type-III the Wilson coefficients corresponding to the electroweak penguins can be enhanced due to the contributions from the charged Higgs mediation leading into enhancement in the branching ratios of $ \bar{B}_s\to ϕπ^0$ and $\bar{B}_s\to ϕρ^0 $ decays. We find that, within two-Higgs doublet models type-II, the enhancement in the branching ratio of $\bar{B}_s\to ϕπ^0$ can not exceed $18\%$ with respect to the SM predictions. For the branching ratio of $\bar{B}_s\to ϕρ^0$, we find that the charged Higgs contribution in this case is small where the branching ratio of $\bar{B}_s\to ϕρ^0$ can be enhanced or reduced by about $4\% $ with respect to the SM predictions. For the case of the two-Higgs doublet models type-III we show that the branching ratio of $\bar{B}_s\to ϕπ^0$ can be enhanced by about a factor $2$ of its value within two-Higgs doublet models type-II. However no sizable enhancement with respect to the SM predictions can be obtained for both $\bar{B}_s\to ϕπ^0$ and $\bar{B}_s\to ϕρ^0$ decays.

description: We study N=1 compactification of IIB supergravity to AdS4. The internal manifold must have SU(2)-structure. By putting some restrictions on the SU(2) torsion classes, we can perform an exhaustive scan of all possible solutions on group manifolds. We show that sourceless solutions don't exist and that the presence of O5 and O7 orientifolds is mandatory. We also find a new solution and relate it by T-duality to a known type IIA solution with O6 planes.

From the Fire: Characterizing the Phoenix Stellar Stream
Creators: name: Tavangar, Kiyan
Publisher: name: University of Chicago
Year: 2021

description: We use six years of data from the Dark Energy Survey (DES) to present a detailed photometric characterization of the Phoenix stream, a 15-degree long, thin, dynamically cold, low-metallicity stream in the southern hemisphere. We use natural splines, a non-parametric modeling technique, to simultaneously fit the stream track, width, and linear density. This updated stream model allows us to improve measurements of the heliocentric distance (17.38±0.08 kpc) and distance gradient (0.01±0.02 kpc/deg) of Phoenix. We measure linear intensity variations on degree scales, as well as wiggles in the stream track on approximately 2-degree scales, suggesting that the stream may have been disturbed during its formation and/or evolution. We recover three peaks and three gaps in linear intensity along with fluctuations in the stream track. Such small-scale fluctuations are not common in other thin streams, and the study of Phoenix offers a unique perspective on the ways that gravitational perturbations affect stellar streams. We discuss possible sources of perturbations to Phoenix including baryonic structures in the Galaxy and dark matter subhalos.

description: We report a 4.8 sigma detection of water absorption features in the day side spectrum of the hot Jupiter HD 189733 b. We used high-resolution (R~100,000) spectra taken at 3.2 microns with CRIRES on the VLT to trace the radial-velocity shift of the water features in the planet's day side atmosphere during 5 h of its 2.2 d orbit as it approached secondary eclipse. Despite considerable telluric contamination in this wavelength regime, we detect the signal within our uncertainties at the expected combination of systemic velocity (Vsys=-3 +5-6 km/s) and planet orbital velocity (Kp=154 +14-10 km/s), and determine a H2O line contrast ratio of (1.3+/-0.2)x10^-3 with respect to the stellar continuum. We find no evidence of significant absorption or emission from other carbon-bearing molecules, such as methane, although we do note a marginal increase in the significance of our detection to 5.1 sigma with the inclusion of carbon dioxide in our template spectrum. This result demonstrates that ground-based, high-resolution spectroscopy is suited to finding not just simple molecules like CO, but also to more complex molecules like H2O even in highly telluric contaminated regions of the Earth's transmission spectrum. It is a powerful tool that can be used for conducting an immediate census of the carbon- and oxygen-bearing molecules in the atmospheres of giant planets, and will potentially allow the formation and migration history of these planets to be constrained by the measurement of their atmospheric C/O ratios.

title: Fine‐Grained Memory Profiling of GPGPU Kernels

Publisher: name: Wiley-Blackwell
Year: 2023

description: Memory performance is a crucial bottleneck in many GPGPU applications, making optimizations for hardware and software mandatory. While hardware vendors already use highly efficient caching architectures, software engineers usually have to organize their data accordingly in order to efficiently make use of these, requiring deep knowledge of the actual hardware. In this paper we present a novel technique for fine‐grained memory profiling that simulates the whole pipeline of memory flow and finally accumulates profiling values in a way that the user retains information about the potential region in the GPU program by showing these values separately for each allocation. Our memory simulator turns out to outperform state‐of‐the‐art memory models of NVIDIA architectures by a magnitude of 2.4 for the L1 cache and 1.3 for the L2 cache, in terms of accuracy. Additionally, we find our technique of fine grained memory profiling a useful tool for memory optimizations, which we successfully show in case of ray tracing and machine learning applications.
