description: We describe two procedures which, given access to one copy of a quantum state and a sequence of two-outcome measurements, can distinguish between the case that at least one of the measurements accepts the state with high probability, and the case that all of the measurements have low probability of acceptance. The measurements cannot simply be tried in sequence, because early measurements may disturb the state being tested. One procedure is based on a variant of Marriott-Watrous amplification. The other procedure is based on the use of a test for this disturbance, which is applied with low probability. We find a number of applications. First, quantum query complexity separations in the property testing model for testing isomorphism of functions under group actions. We give quantum algorithms for testing isomorphism, linear isomorphism and affine isomorphism of boolean functions which use exponentially fewer queries than is possible classically, and a quantum algorithm for testing graph isomorphism which uses polynomially fewer queries than the best algorithm known. Second, testing properties of quantum states and operations. We show that any finite property of quantum states can be tested using a number of copies of the state which is logarithmic in the size of the property, and give a test for genuine multipartite entanglement of states of n qubits that uses O(n) copies of the state. Third, correcting an error in a result of Aaronson on de-Merlinizing quantum protocols. This result claimed that, in any one-way quantum communication protocol where two parties are assisted by an all-powerful but untrusted third party, the third party can be removed with only a modest increase in the communication cost. We give a corrected proof of a key technical lemma required for Aaronson's result.

description: The unique topology and physics of chiral superlattices make their self-assembly from nanoparticles a holy grail for (meta)materials. Here we show that tetrahedral gold nanoparticles can spontaneously transform from a perovskite-like low-density phase with corner-to-corner connections into pinwheel assemblies with corner-to-edge connections and denser packing. While the corner-sharing assemblies are achiral, pinwheel superlattices become strongly mirror-asymmetric on solid substrates as demonstrated by chirality measures. Liquid-phase transmission electron microscopy and computational models show that van der Waals and electrostatic interactions between nanoparticles control thermodynamic equilibrium. Variable corner-to-edge connections among tetrahedra enable fine-tuning of chirality. The domains of the bilayer superlattices display strong chiroptical activity identified by photon-induced near-field electron microscopy and finite-difference time-domain simulations. The simplicity and versatility of the substrate-supported chiral superlattices facilitate manufacturing of metastructured coatings with unusual optical, mechanical and electronic characteristics.
title: Firm Heterogeneity and the Transmission of Central Bank Credit Policy
Creators: name: Kuhmann, Konrad
Publisher: name: Hertie School
Year: 2023

description: I study the role of firm heterogeneity for the transmission of unconventional monetary policy in the form of “credit policy” à la Gertler and Karadi (2011). To this end, I lay out a Two-Agent New-Keynesian model with financially constrained and unconstrained firms and a financial intermediary with an endogenous leverage constraint. I find that, when firms are heterogeneous, aggregate investment is substantially less responsive to credit policy compared to an identical firm setting. Moreover, when debt markets are segmented, credit policy directed exclusively at financially unconstrained firms is most effective. My paper provides a tractable framework to illustrate mechanisms through which firm heterogeneity affects the transmission of credit policy. According to my findings, the presence of firm heterogeneity can be expected to make credit policy less effective than predicted by a representative agent framework.

description: The effects associated with interatomic hoppings of excitons and the excitonic Bose condensate formation in the strongly correlated spin crossover systems are considered in the framework of the effective Hamiltonian for the two-band Kanamori model. The appearance of antiferromagnetic ordering due to the exciton order is found even in the absence of interatomic exchange interaction. The spectrum of excitonic excitations is calculated at various points of the "temperature vs. crystal field" phase diagram. Outside the region of exciton ordering, the spectrum has a gap, which vanishes at the boundary of the exciton condensate phase. The non-uniform spectral weight distribution over the Brillouin zone is found. The role of electron-phonon interaction is discussed as well.

description: The response of electromagnetic (EM) fields that are produced in non-central heavy-ion collisions to electromagnetically charged quark gluon plasma can be understood in terms of charge transport and charge diffusion in the hot QCD medium. This article presents a perspective on these processes by investigating the temperature behavior of the related transport coefficients, {\it viz.} electrical conductivity and the charge diffusion coefficients along with charge susceptibility. In the process of estimating them, thermal relaxation times for quarks and gluons have been determined first. These transport coefficients have been studied by solving the relativistic transport equation in the Chapman-Enskog method. For the analysis, $2\rightarrow 2$, quark-quark, quark-gluon and gluon-gluon scattering processes are taken into account along with an effective description of hot QCD Equations of state (EOSs) in terms of temperature dependent effective fugacities of quasi-quarks (anti-quarks) and quasi-gluons. Both improved perturbative hot QCD EOSs at high temperature and a lattice QCD EOS are included for the analysis. The hot QCD medium effects entering through the quasi-particle momentum distributions along with an effective coupling, are seen to have significant impact on the temperature behavior of these transport parameters along with the thermal relaxation times for the quasi-gluons and quasi-quarks

description: Optically active defects in 2D materials, such as hexagonal boron nitride (hBN) and transition metal dichalcogenides (TMDs), are an attractive class of single-photon emitters with high brightness, room-temperature operation, site-specific engineering of emitter arrays, and tunability with external strain and electric fields. In this work, we demonstrate a novel approach to precisely align and embed hBN and TMDs within background-free silicon nitride microring resonators. Through the Purcell effect, high-purity hBN emitters exhibit a cavity-enhanced spectral coupling efficiency up to $46\%$ at room temperature, which exceeds the theoretical limit for cavity-free waveguide-emitter coupling and previous demonstrations by nearly an order-of-magnitude. The devices are fabricated with a CMOS-compatible process and exhibit no degradation of the 2D material optical properties, robustness to thermal annealing, and 100 nm positioning accuracy of quantum emitters within single-mode waveguides, opening a path for scalable quantum photonic chips with on-demand single-photon sources.
Lewis-Riesenfeld invariants for PT-symmetrically coupled oscillators from two dimensional point transformations and Lie algebraic expansions

description: We construct Lewis-Riesenfeld invariants from two dimensional point transformations for two oscillators that are coupled to each other in space in a PT-symmetrical and time-dependent fashion. The non-Hermitian Hamiltonian of the model is conveniently expressed in terms of generators of the symplectic $sp(4)$ Lie algebra. This allows for an alternative systematic approach to find Lewis-Riesenfeld invariants leading to a set of coupled differential equations that we solve by using time-ordered exponentials. We also demonstrate that point transformations may be utilized to directly construct time-dependent Dyson maps from their respective time-independent counterparts in the reference system.

Year: 2002

description: An institution-based retrospective cohort study was carried out in four hospitals located in four zones of the Somali Region to assess the magnitude and pattern of resistance to 5 essential anti-tuberculosis drugs currently in use and to determine the risk factors associated with drug resistant TB. A total of 190 patients were enrolled consecutively between March and August, 2001; culture was performed on 187 specimens and 127 of these (41 re-treatment and 86 new cases) underwent drug susceptibility tests (DST) to five first-line anti-tuberculosis drugs (isoniazid, rifampicin, ethambutol, streptomycin and thioacetazone) at the Ethiopian Health and Nutrition Research Institute in Addis Ababa. Serology for HIV was done on 112 of the 127 patients with MTB isolates which were included in the analysis. Resistance to any drug was 17.4% in new cases and 46.3% in previously treated cases. MDRTB was seen in 1.2% and 10% of the new and re-treatment cases, respectively. Double drug resistance ranged between 1.2%-2.3% and 7.3-14.6% for new and re-treatment cases, respectively while triple and four-drug resistance were 1.2% for new cases and ranged between 5-7.5% in re-treatment cases. Resistances to all the 5 drugs were 1.9% and 7.3% in new and re-treatment cases, respectively. The differences in resistance level between the two groups were statistically significant at the P<0.01 level. Ethambutol resistance of 2.3% in new cases and 12.2% in re-treatment cases were the highest recorded in the country so far. Resistance to rifampicin is increasing in Eastern part of Ethiopia. The over all HIV seroprevalence was 6.3%, lowest in Sub-Saharan Africa; it was 4% in new cases and 11.4% in the old ones but the difference did not achieve significance due to a small sample size. 10 The prevalence of drug resistance in general and MDR-TB in particular are high in the Somali region. Regulating the private sector and strict control of drugs in the black market, active involvement of the public, the private sector and others concerned, and considering alternative regimens for those harboring resistant strains are suggested for averting the dangers of wide spread MDR-TB.

description: Lorentz symmetry violations can be parametrized by an effective field theory framework that contains both general relativity and the standard model of particle physics called the standard-model extension (SME). We present new constraints on pure gravity SME coefficients obtained by analyzing lunar laser ranging (LLR) observations. We use a new numerical lunar ephemeris computed in the SME framework and we perform a LLR data analysis using a set of 20721 normal points covering the period of August, 1969 to December, 2013. We emphasize that linear combination of SME coefficients to which LLR data are sensitive and not the same as those fitted in previous postfit residuals analysis using LLR observations and based on theoretical grounds. We found no evidence for Lorentz violation at the level of $10^{-8}$ for $\bar{s}^{TX}$, $10^{-12}$ for $\bar{s}^{XY}$ and $\bar{s}^{XZ}$, $10^{-11}$ for $\bar{s}^{XX}-\bar{s}^{YY}$ and $\bar{s}^{XX}+\bar{s}^{YY}-2\bar{s}^{ZZ}-4.5\bar{s}^{YZ}$ and $10^{-9}$ for $\bar{s}^{TY}+0.43\bar{s}^{TZ}$. We improve previous constraints on SME coefficient by a factor up to 5 and 800 compared to postfit residuals analysis of respectively binary pulsars and LLR observations.

description: We consider an explanation of CDF II W bosom mass anomaly by $Z-Z'$ mixing with $U(1)_R$ gauge symmetry under which right-handed fermions are charged. It is found that $U(1)_R$ is preferred to be leptophobic to accommodate the anomaly while avoiding other experimental constraints. In such a case we require extra charged leptons to cancel quantum anomalies and the SM charged leptons get masses via interactions with the extra ones. These interactions also induce muon $g-2$ and lepton flavor violations. We discuss muon $g-2$, possible flavor constraints, neutrino mass generation via inverse seesaw mechanism, and collider physics regarding $Z'$ production for parameter space explaining the W boson mass anomaly.

description: Events from alpha interactions on the surfaces of germanium detectors are a major contribution to the background in germanium-based searches for neutrinoless double-beta decay. Surface events are subject to charge trapping, affecting their pulse shape and reconstructed energy. A study of alpha events on the passivated end-plate of a segmented true-coaxial n-type high-purity germanium detector is presented. Charge trapping is analysed in detail and an existing pulse-shape analysis technique to identify alpha events is verified with mirror pulses observed in the non-collecting channels of the segmented test detector. The observed radial dependence of charge trapping confirms previous results. A dependence of the probability of charge trapping on the crystal axes is observed for the first time. A first model to describe charge trapping effects within the framework of the simulation software SolidStateDetectors.jl is introduced. The influence of metalisation on events from low-energy gamma interactions close to the passivated surface is also presented.

description: The paper discusses the issues of the long time taken to complete the trial process in India, which is related to the poor judge-population ratio and the emphasis on speedy disposal of cases rather than due process. It also highlights the higher conviction rates in fast track courts despite concerns about the adage of proving a case beyond reasonable doubt. The paper suggests that to reduce the pendency of cases, India needs to increase its judge-population ratio and improve court infrastructure.

description: Understanding and controlling the interaction between the excitonic states of a quantum emitter and the plasmonic modes of a nanocavity is one of the most relevant current scientific challenges, key for the development of many applications, from quantum information processing devices to polaritonic catalysts. In this paper we demonstrate that the tunnel electroluminescence of C60 nanocrystals enclosed in the plasmonic nanocavity between a metallic surface and the tip of a Scanning Tunnelling Microscope, and isolated from the metal surface by a thin NaCl film, can be switched from a broad emission spectrum, revealing the plasmonic modes of the cavity, to a narrow band emission, displaying only the excitonic states of the C60 molecules by changing the bias voltage applied to the junction. Plasmonic emission is found in the same voltage region in which the rate of inelastic tunnel transitions is large and, thus, vanishes for large voltages. Excitonic emission, on the other hand, dominates the spectra in the high-voltage region in which the inelastic rate is low, demonstrating that the excitons cannot be created by an inelastic tunnel process. These results point towards new possible mechanisms to explain the tunnel electroluminescence of quantum emitters and offer new avenues to develop electrically tuneable nanoscale light sources.

description: We report the achievement of spatial confinement of muonium atoms (the bound state of a positive muon and an electron). Muonium emitted into vacuum from mesoporous silica reflects between two SiO$_2$ confining surfaces separated by 1 mm. From the data, one can extract that the reflection probability on the confining surfaces kept at 100 K is about 90% and the reflection process is well described by a cosine law. This technique enables new experiments with this exotic atomic system and is a very important step towards a measurement of the 1S-2S transition frequency using continuous wave laser spectroscopy.

description: We introduce four new datasets within the Swiss jurisdiction for two classification and two generative tasks and yielded significant insights into the domain of legal NLP. We discovered the predominance of comprehensive pre-training over model size in the classification tasks. In the generation tasks, larger models generally outperformed smaller ones, though the generated text often lacked in logical coherence. This exposes the current models’ limitations and underlines the necessity for enhancements in these tasks. This research sets the stage for future investigations, emphasizing the potential of comprehensive pre- training and the improvement of logical coherence in legal language models.

description: Introduction: Abortion is one of the major causes for maternal mortality in the world as well as in our country. Unintended pregnancies which end up in abortion occur due to contraception method nonuse or misuse. To limit unintended pregnancies and avoid repeated abortions promoting immediate post abortion contraception is crucial. Objective: The objective of the study was to assess the proportion of post abortion contraception acceptance among clients received abortion care and identify factors associated with post-abortion contraception acceptance/non-acceptance. Methods: A cross-sectional study was undertaken in 8 health sectors in Burayu town Oromiya regional state from January 2014 to June 2014. Asampleof415women'swereselectedbymeansofsystematicsampling techniques and three hundred nightly one abortion clients were interviewed in the health centers and clinics on the use/ acceptance of post abortion family planning (PAFP). Datawerecollectedthroughpre-testedstructuredquestionnaire.Then datawasenteredby usingEPI Info version 3.5.4 and exported toSPSS foranalysis. Descriptive statistics: frequency, percentage and cross tabulation were done. Logisticregression analysis wasconductedusingSPSSversion21statisticalpackage. Significances wereconsideredatP-value less than 0.05(P<0.05). Results: Among 391 study subjects, 346(88.5%) of the respondents who has got abortion care service accepted post abortal family planning. Women,who made independent decision had four times (OR= 3.815, 95% CI (1.212 - 12.00)) more likely to accept PAFP compared with those decided by husband and wife. Women those did not get counseling were 76.1% (OR= 0.239, 95% CI (0.068 -0.846)) less likely to accept PAFP compared to women who were counseled. The most frequent reasons mentioned by the participants of the study for not accepting contraceptive methods were; they consider it as sin,it affects health, and it should not be the first choice. Conclusion: More than eighty eight percent (88.5%) of women who came for abortion care service accepted post abortion family planning. counseling services, independent decision on FP and income were found to be determinant factors for PAFP acceptance. Therefore emphasis on PAFP education should be given to increase acceptance rates

description: It is known that HLL-type schemes are more dissipative than schemes based on characteristic decompositions. However, HLL-type methods offer greater flexibility to large systems of hyperbolic conservation laws because the eigenstructure of the flux Jacobian is not needed. We demonstrate in the present work that several HLL-type Riemann solvers are provably entropy stable. Further, we provide convex combinations of standard dissipation terms to create hybrid HLL-type methods that have less dissipation while retaining entropy stability. The decrease in dissipation is demonstrated for the ideal MHD equations with a numerical example.

Criticality Prediction and Information Retrieval in Swiss Legal Data
Creators: name: Stern, Ronja
Publisher: name: Zenodo
Year: 2023

description: We introduce two novel tasks for legal Natural Language Processing (NLP), aiming to add diversity to the field. As certain cases may have a more significant impact on jurisdiction than others, legal experts are interested in predicting the level of controversy surrounding a case. Additionally, being able to retrieve relevant laws or Leading Decision (BGE) a case depends on could greatly reduce court costs. The potential use cases for both tasks are numerous and not only include reducing court delays but also prioritizing cases for better judgments. To our knowledge, there have been no previous attempts to predict the criticality of a legal case or the retrieve relevant laws and BGE in Switzerland.
 To address this, we publicly release two multilingual datasets containing cases from the Federal Supreme Court of Switzerland. The Swiss-Criticality-Prediction dataset features two approaches for labeling cases as critical, while the Swiss-Doc2doc-IR dataset includes links for each case to cited laws and BGE. In the Criticality task, we assess the performance of multilingual BERT-based models. For the Information Retrieval task, we evaluate existing models from the BEIR benchmark. We observe that all models fall short in their performance. Nonetheless, we find that domain- specific pre-training proves to be advantageous for both tasks.

A High Fraction of Double-peaked Narrow Emission Lines in Powerful Active Galactic Nuclei

Year: 2016
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: One percent of redshift z~0.1 Active Galactic Nuclei (AGNs) show velocity splitting of a few hundred km/s in the narrow emission lines in spatially integrated spectra. Such line profiles have been found to arise from the bulk motion of ionized gas clouds associated with galactic-scale outflows, merging pairs of galaxies each harboring a supermassive black hole (SMBH), and/or galactic-scale disk rotation. It remains unclear, however, how the frequency of narrow-line velocity splitting may depend on AGN luminosity. Here we study the correlation between the fraction of Type 2 AGNs with double-peaked narrow emission lines and AGN luminosity as indicated by [O III]5007 emission-line luminosity L_[O III]. We combine the sample of Liu et al. (2010) at z~0.1 with a new sample of 178 Type 2 AGNs with double-peaked [O III] emission lines at z~0.5. We select the new sample from a parent sample of 2089 Type 2 AGNs from the SDSS-III/Baryon Oscillation Spectroscopic Survey. We find a statistically significant (~4.2σ) correlation between L_[O III] and the fraction of objects that exhibit double-peaked narrow emission lines among all Type 2 AGNs, corrected for selection bias and incompleteness due to [O III] line width, equivalent width, splitting velocity, and/or equivalent width ratio between the two velocity components. Our result suggests that galactic-scale outflows and/or merging pairs of SMBHs are more prevalent in more powerful AGNs, although spatially resolved follow up observations are needed to resolve the origin(s) for the narrow-line velocity splitting for individual AGNs.

description: The presence of the Radcliffe wave is shown both in the positions and in the vertical velocities of masers and radio stars belonging to the Local Arm. This gives the impression that the structure of the Radcliffe wave is not a wave in the full sense of the word. It is more like a local high-amplitude burst, rapidly fading away. Moreover, this structure has the largest amplitude in the immediate vicinity of the Sun, where the main ``contributors'' are the Gould Belt stars. Based on the spectral analysis of masers, the following estimates of the geometric and kinematic characteristics of the wave were obtained: the largest value of the vertical coordinate $z_{max}=87\pm4$ pc and the wavelength $λ=2.8\pm0.1$ kpc, the vertical velocity perturbation amplitude reaches $W_{max}=5.1\pm0.7$ km s$^{-1}$ and the wavelength found from vertical velocities is $λ=3.9\pm1.6$ kpc. The Radcliffe wave also manifests itself in the positions of very young stars that have not reached the main sequence stage. We extracted a sample of such stars from the Gaia DR2$\times$AllWISE database and obtained the following estimates from them: $z_{max}=118\pm3$ pc and wavelength $λ=2.0\pm0.1$ kpc.

description: A community based cross sectional study was conducted from October to December 2004 in Ayssaita and Dubti towns in Afar Regional state to assess factors affecting utilization of maternal health care services among women during their third trimester of pregnancy and with in 12 months post delivery preceding the survey. Data were collected using a pre-tested and standardized questionnaire in 642 eligible women from four kebeles by clustered random sampling technique. Analysis revealed that close to 80% of the women had at least one prenatal visit during their recent pregnancy. Most of the antenatal care (ANC) attendants made their first visit during their second trimester of pregnancy. Among ANC users 53% of had less than four antenatal care contacts. Majority of deliveries took place at home, of which 93.7% were attended by TBAs. Absences of a health problem, lack of awareness, work overload and distant health service were the main reasons for no ANC attendance. Presence of relatives nearby, more trust on TBAs, lack of privacy, and male professionals assistance during labor at health facilities, were the main reasons cited for resorting to home delivery. Of the total, 45% of the women had knowledge on danger signals of pregnancy and childbirth related health problems. The majorities were able to name the danger signs of pregnancy related health problems. Most of the women neither perceived pregnancy related morbidity nor experienced illness in the recent pregnancy. Bivariant and multivariate analysis showed significant association between ANC attendance and maternal age, occupation, wanted pregnancies, illness experience and perceived susceptibility to dangerous health problems related to pregnancy and childbirth. Education (OR=5.26,95% viii CI=3.12,8.92), religion (OR=2.77,95% CI=1.80,4.27), income (OR=2.59,95% CI=1.55,5.00) and ANC attendance (OR=0.21,95% CI=0.13, 0.35) were associated with choice of delivery site. Orders of pregnancy and husbands' attitude were found to be strong predictor of both antenatal care and skilled attendance at birth. In conclusion, the study revealed low maternal health care utilization in the area. Demographic and socio cultural factors were found to be barriers to utilization of maternal health care services. Increasing maternal health service coverage and promotion of IEC in the community are recommended. Key words: Maternal health care, antenatal care, preferred place of delivery, Afar Region.
Multi-flavor string-net models

description: We generalize the string-net construction to multiple flavors of strings, each of which is labeled by the elements of an abelian group $G_i$. The same flavor of strings can branch while different flavors of strings can cross one another and thus they form intersecting string-nets. We systematically construct the exactly soluble lattice Hamiltonians and the ground state wave functions for the intersecting string-net condensed phases. We analyze the braiding statistics of the low energy quasiparticle excitations and find that our model can realize all the topological phases as the string-net model with group $G=\prod_i G_i$. In this respect, our construction suggests several ways of building lattice models which realize topological order $G$. They correspond to intersecting string-net models with various choices of flavors of strings associated with different decomposition of $G$. In fact, our construction concretely demonstrates the K\text{ü}nneth formula by constructing various lattice models with the same topological order. As an example, we construct the $G=\mathbb{Z}_2\times \mathbb{Z}_2 \times \mathbb{Z}_2 $ string-net model which realizes a non-abelian topological phase by properly intersecting three copies of toric codes.

description: The Fe14Nd2B-based permanent magnets are technologically sought-after for energy conversion due to their unparalleled high energy product (520 kJ/m3). For such 14:2:1 phases of different compositions, determining the magnetization from the measured magnetic moment is often bottlenecked by lack of mass density. We present a machine learning (ML) mass density model for 14:2:1 phases using chemical composition-based features (representing 33 elements) and optionally lattice parameter (LP) features. The datasets for training and testing contain 190 phases (177 compositionally different) with their literature reported densities and LP. With an ML model with merely compositional features, we achieved a low mean-absolute-error of 0.51% on an unseen test-dataset.

description: Guiding many-body systems to desired states is a central challenge of modern quantum science, with applications from quantum computation to many-body physics and quantum-enhanced metrology. Approaches to solving this problem include step-by-step assembly, reservoir engineering to irreversibly pump towards a target state, and adiabatic evolution from a known initial state. Here we construct low-entropy quantum fluids of light in a Bose Hubbard circuit by combining particle-by-particle assembly and adiabatic preparation. We inject individual photons into a disordered lattice where the eigenstates are known & localized, then adiabatically remove this disorder, allowing quantum fluctuations to melt the photons into a fluid. Using our plat-form, we first benchmark this lattice melting technique by building and characterizing arbitrary single-particle-in-a-box states, then assemble multi-particle strongly correlated fluids. Inter-site entanglement measurements performed through single-site tomography indicate that the particles in the fluid delocalize, while two-body density correlation measurements demonstrate that they also avoid one another, revealing Friedel oscillations characteristic of a Tonks-Girardeau gas. This work opens new possibilities for preparation of topological and otherwise exotic phases of synthetic matter.
Avoiding the Goldstone Boson Catastrophe in general renormalisable field theories at two loops

description: We show how the infra-red divergences associated to Goldstone bosons in the minimum condition of the two-loop Landau-gauge effective potential can be avoided in general field theories. This extends the resummation formalism recently developed for the Standard Model and the MSSM, and we give compact, infra-red finite expressions in closed form for the tadpole equations. We also show that the results at this loop order are equivalent to (and are most easily obtained by) imposing an "on-shell" condition for the Goldstone bosons. Moreover, we extend the approach to show how the infra-red divergences in the calculation of the masses of neutral scalars (such as the Higgs boson) can be eliminated. For the mass computation, we specialise to the gaugeless limit and extend the effective potential computation to allow the masses to be determined without needing to solve differential equations for the loop functions -- opening the door to fast, infra-red safe determinations of the Higgs mass in general theories.

description: We provide a universal discussion of the interplay between Rydberg-state electromagnetically induced transparency (EIT) and optical pumping (OP) in a thermal Rb87 medium. By pumping the population to one single Hyperfine/Zeeman state, we can enhance the interaction strength and, in principle, amplify the EIT peak. According to our measurements, the EIT peak height can be improved by a factor of two or reduced by one order of magnitude, and linewidth was slightly narrowed by the pumping effect. Similar behavior is also seen by increasing the optical density (OD) of the medium. The EIT feature is predicted quantitatively using a Doppler-free non-perturbation numerical calculation. With and without the optical pumping field, the EIT peak heights collapse onto the same theoretical curve, showing that OP and varying OD have the same effect. In both simulations and measurements, Rydberg EIT enhancement through OP is dependent on the intensity of the probe field and the OD. Our work clarifies the underlying mechanisms of optical pumping and advances Rydberg-atom research.

description: In this paper, we propose a new finite element approach to simulate the time-dependent Ginzburg-Landau equations under the temporal gauge, and design an efficient preconditioner for the Newton iteration of the resulting discrete system. The new approach solves the magnetic potential in H(curl) space by the lowest order of the second kind Nedelec element. This approach offers a simple way to deal with the boundary condition, and leads to a stable and reliable performance when dealing with the superconductor with reentrant corners. The comparison in numerical simulations verifies the efficiency of the proposed preconditioner, which can significantly speed up the simulation in large-scale computations.

description: We show that radiofrequency (RF) radiation may be used to create Feshbach resonances in ultracold gases of alkali-metal atoms at desired magnetic fields that are convenient for atomic cooling and degeneracy. For the case of $^{39}$K+$^{133}$Cs, where there are no RF-free resonances in regions where Cs may be cooled to degeneracy, we show that a resonance may be created near 21~G with 69.2~MHz RF radiation. This resonance is almost lossless with circularly polarized RF, and the molecules created are long-lived even with plane-polarized RF.
