description: The entanglement between two weakly coupled bosonic Josephson junctions is studied in relation to the classical mixed phasespace structure of the system, containing symmetry-related regular islands separated by chaos. The symmetry-resolved entanglement spectrum and bi-partite entanglement entropy of the system's energy eigenstates are calculated and compared to their expected structure for random states that exhibit complete or partial ergodicity. The entanglement spectra of chaos-supported eigenstates match the microcanonical structure of a Generalized Gibbs Ensemble due to the existence of an adiabatic invariant that restricts ergodization on the energy shell. The symmetry-resolved entanglement entropy of these quasistochastic states consists of a mean-field maximum entanglement term and a fluctuation correction due to the finite size of the constituent subsystems. The total bi-partite entanglement entropy of the eigenstates correlates with their chaoticity. Island-supported eigenstates are macroscopic Schrödinger cat states for particles and excitations, with substantially lower entanglement.

description: Past research documents a clear link between gender role norms and young men and women’s interest in divergent careers. Generally, individuals are more likely to take on careers that they perceive as normative for their own gender. However, past research has focused primarily on heterosexual populations, and has not considered in depth whether mainstream norms might have different, possibly weaker, effects on career decisions among LGBTQ+ populations. There is some preliminary evidence suggesting that non-heterosexual individuals endorse less traditional gender roles and might make less gender-normative career choices themselves. In a sample of heterosexual vs. non-heterosexual individuals from 46 countries (after exclusions), we collected data on participants’ sexual orientation, their own injunctive gender role norms of who should enter HEED and STEM careers, their perceptions of others’ injunctive norms for HEED and STEM careers, and well as their own interest in these careers. We examine whether non-heterosexual (compared to fully heterosexual) individuals endorse less traditional gender role norms and show a weaker relationship between their perception of mainstream norms and their own career interests – possibly especially in countries where homosexuality is relatively highly accepted (i.e., in countries where homosexuality is not accepted, non-heterosexual people might still stick to highly stereotypic career choices). The attached document details all our key hypotheses and analysis plans.

description: We develop the formalism for calculating the decay rate of neutrinoless double beta decay to the $2^+$ excited states within L-R symmetric model. We consider the effects from induced hadronic currents up to NLO. The QRPA method in a spherical basis is adopted for the nuclear many-body calculation and the corresponding nuclear matrix elements are given. Also, the phase space factors are obtained with numerical electron wave functions. Our results suggest that the nuclear matrix elements are nucleus dependent and they are generally smaller than that of the decay to the ground states. And finally, we give a naive analysis of how current experiment data constrains the L-R symmetric model.

Detection and Treatment of Mental Illness Among Prison Inmates: A Validation of Mental Health Screening at Intake to Correctional Service of Canada

description: Mental health screening is frequently recommended to facilitate earlier detection of mental illness in prisons. For this goal to be achieved: (1) the screening process must be accurate; (2) appropriate follow-up treatment must be provided; (3) the treatment must lead to improved outcomes. The current thesis aimed to evaluate mental health screening in relation to these three criteria by studying 13, 281 prisoners admitted to Correctional Service of Canada. Screening achieved comparable accuracy to tools that have been studied internationally and many inmates received at least some treatment. However, interruptions in treatment were frequent and long-term treatment was rare. There was weak evidence that treatment led to reduced rates of institutional incidents of suicide, self-harm, victimization and violence. While screening remains widely endorsed, further study of its impacts is needed to maximize its value. This could include considering alternatives to screening itself, or as follow-up for those who screen positive.

description: At the United Nations Climate Change Conference in Paris in 2015 ambitious targets for responding to the threat of climate change have been set: limiting global temperature increase to “well below 2 °C […] and to pursue efforts to limit the temperature increase to 1.5 °C”. However, calculating the CO2 budget for 1.5 °C, it becomes clear that there is nearly no room left for future emissions. Scenarios suggest that negative emission technologies will play an even more important role for 1.5 °C than they already play for 2 °C. Especially against this background the feasibility of the target(s) is hotly debated, but this debate does not initiate the next steps that are urgently needed. Already the negotiations have featured the move from targets to implementation which is needed in the coming decade. Most importantly, there is an urgent need to develop and implement instruments that incentivize the rapid decarbonization. Moreover, it needs to be worked out how to link the climate and development agenda and prevent a buildup of coal power causing lock-in effects. Short term entry points into climate policy should now be in the focus instead of the fruitless debate on the feasibility of targets.

description: Many fruit fly species have a detrimental impact on food production. Lure and kill and mass trapping methods are becoming more important for crop protection, but currently, Island Fly (Dirioxa pornia) does not have a specific attractive lure for males and females. This study is initial research into olfactory responses to gut bacteria emissions. Fruit flies use olfactory cues for locating bacteria that assist in their development cycle. The ingestion of food together with naturally occurring bacteria allows a microbiome to form in their intestinal tract. This project investigated the gut microbiome of laboratory reared Island Flies, the chemical composition of the volatiles released from these microbes by GC-MS and the attractiveness of Island Flies to the volatile isolates using Y-tube olfactometry, electroantennography and wind tunnel experiments. All bioassay results of Island flies showed a rapid attraction towards the identified bacterial volatile isolates of Bacillus sp. and deterrence towards Citrobacter freundii. Other bacterial isolates of Bacillus subtilis, Klebsiella oxytoca and Providencia rettgeri showed low to moderate attractions respectively. Bacillus sp. uniquely had alkanes, some alcohols, aldehydes and nitrogen containing compounds while C. freundii had many sulphur-containing compounds and acids. Further studies on these compounds may assist in the development of a microbial-based lure.
People do not empathise and help others based on facial resemblance

description: Altruism may have evolved through kin selection by maximising inclusive fitness, so people may have evolved to preferentially help kin over non-kin. Previous research suggests that empathy may be one of the main contributors to helping behaviour, and that people trust others who look similar to themselves. However, whether this leads to helping, and whether empathy towards others changes according to their physical similarity remains unknown. The aim of the thesis is to examine the effect of within-race self-similarity on cognitive empathy, emotional empathy, and helping. The faces of 56 Caucasian participants (27 male, 27 female; aged 18-29) were secretly recorded responding to happy and sad video clips. Happy and sad composite faces (validated by a rating task) were morphed to look similar and dissimilar to each participant. A total of 15 male and 18 female participants returned to make judgements of each face, including how well they recognise the faces’ emotional expression, how much they feel that emotion themselves, and whether they chose to help people with a similar or a dissimilar face in a low risk scenario. There was no significant difference for either cognitive empathy, emotional empathy, or helping similar compared to dissimilar faces. There was also no significant difference in cognitive compared to emotional empathy for the preference of similar over dissimilar faces. Nor did a self-preference in cognitive empathy nor a self-preference in emotional empathy significantly predict a self-preference in helping. This study has demonstrated that empathy and helping are not affected by self-resemblance, and offers an alternative way that kin selection functions in humans.
A functional approach to teaching English tenses to speakers of other languages: the case of teaching English to adults in Serbia

Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis investigates how a pedagogy based on systemic-functional linguistics (SFL) can benefit teaching English tenses to adults in Serbia. Using a functional tense description within the SFL-based teaching/learning cycle should benefit language learners because it foregrounds the logical architecture of tense selection in English texts. There is a gap in research, however, exploring possible SFL applications in teaching tenses in English as a second/foreign language. Data for this study were collected through surveys with 24 English teachers of adult learners in Serbia, followed by semi-structured interviews with three survey respondents. The findings indicate that, despite the influence of a form-focused grammar pedagogy on their current practices, the participant-teachers believe in the benefits of a text-based approach to teaching grammar through scaffolding. The study also suggests that learners struggle when tense forms reflect more than one temporal relation, arguably due to the Serbian tense system. A functional pedagogy can provide English teachers with pedagogical tools for a text-based approach to teaching tenses, whereas the recursive SFL-based English tense system can enable learners to observe all time references influencing tense choice. One implication of this study is that a functional approach to teaching English tenses should be endorsed by English teachers in Serbia if provided with teacher training. Another implication is that such a pedagogy should assist in overcoming the difficulties arising from the learner’s first language, which encourages the replication of this study involving different language groups.

description: There are many single field inflationary models that are consistent with the recent Planck 2018 measurements of the spectral index $n_s$ and tensor-to-scalar ratio $r$. Despite good agreement with observational data some of these models suffer from having unregularized potentials which would produce a collapsing universe shortly after the end of inflation. In this paper we show that how one chooses to correct the behaviour potential towards the end of inflation can have a significant effect on the inflationary predictions of the model, specifically in the case of quartic hilltop and radiatively corrected Higgs inflation.

description: Numerical simulations of thermal convection in the Earth's mantle often employ a pseudoplastic rheology in order to mimic the plate-like behavior of the lithosphere. Yet the benchmark tests available in the literature are largely based on simple linear rheologies in which the viscosity is either assumed to be constant or weakly dependent on temperature. Here we present a suite of simple tests based on nonlinear rheologies featuring temperature, pressure, and strain rate-dependent viscosity. Eleven different codes based on the finite volume, finite element, or spectral methods have been used to run five benchmark cases leading to stagnant lid, mobile lid, and periodic convection in a 2-D square box. For two of these cases, we also show resolution tests from all contributing codes. In addition, we present a bifurcation analysis, describing the transition from a mobile lid regime to a periodic regime, and from a periodic regime to a stagnant lid regime, as a function of the yield stress. At a resolution of around 100 cells or elements in both vertical and horizontal directions, all codes reproduce the required diagnostic quantities with a discrepancy of at most approximate to 3% in the presence of both linear and nonlinear rheologies. Furthermore, they consistently predict the critical value of the yield stress at which the transition between different regimes occurs. As the most recent mantle convection codes can handle a number of different geometries within a single solution framework, this benchmark will also prove useful when validating viscoplastic thermal convection simulations in such geometries.

description: We present results on NLO electroweak (EW) corrections to multiple massive boson production processes at a future muon collider. Inclusive cross sections with $\mathcal{O}(α)$ corrections for processes for up to four bosons in the final state as well as differential distributions for $HZ$ production are computed for $\sqrt{s}=3$, $10$ and $14$ TeV by using FKS subtraction in the NLO EW automated Monte-Carlo framework WHIZARD+RECOLA. Large logarithmic effects due to collinear ISR and EW virtual correction factors as well as the impacts of an energy cut on hard photons are discussed with an emphasis on the properties of Higgsstrahlung. The potential of a proposed muon collider for studying physics of the EW sector is underlined by the EW corrections significantly affecting observables for processes at high energies and boson multiplicities.

Justinian I and Gregory the Great: the legislative ideology of a civic bishop
Creators: name: Thorne, Charles
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis argues that the ideology of Byzantine Emperor Justinian I (527-565) is discernible in the behaviour of Roman Bishop Gregory the Great (590-604). My hypothesis rests upon the legislative, not tangible, influence of the emperor upon Gregory, who lived several decades after the death of Justinian. Noted for his superlative piety,1 Justinian framed perhaps his greatest achievement, the Corpus Iuris Civilis, as a homage to divine ordination and his personal role in a reinvigorated celestial dispensation. As Justinian is best known for his legal codification, Gregory’s own magnum opus is a vast collection of private letters: numbering over 800, the letters cover all aspects of his episcopate, be it social, religious or political, and thus afford the reader an unrivalled insight into the world of a 6th century Roman Bishop. Therefore, by analysing the parallels between the Corpus Iuris Civilis and the behaviour of Gregory, as expressed through his letters, we can assess the influence of Justinian upon Gregory. Justinian’s law code encompasses every perceivable aspect of private and public life, and so the specific focus here is upon Justinian’s ideology regarding the civic role of bishops. Following imperial enfranchisement under Constantine I (306-337), Christian bishops grew in prestige, gradually accruing authority well beyond the traditional ecclesiastical sphere. It is clear from the Corpus Iuris Civilis that Justinian envisaged the bishop as taking a much more active role in municipal administration, a role fostered by the evolving nature of contemporary urban society. Thus, the aim of this study is to assess the ideological influence of Justinian, through the medium of his law code, and in the context of the civic role of bishops, upon the episcopate of Gregory the Great.

Migration patterns to Russia from Central Asia and the Baltics since independence
Creators: name: Potter, Elizabeth Anne
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: This paper examines migration trends in the former Soviet Union with a focus on migration inflows to the Russian Federation since independence. Four countries, three in Central Asia and one as an example of the broader trends in the Baltic countries, Estonia, have been selected for a more thorough analysis. The political and economic conditions since the dissolution of the Soviet Union are assessed for each of these countries and Russia using economic data and internationally recognized political measures. Although there are similarities on how economic and political factors affect migration and broad characterizations of migration periods can be established for the region such as Andrei Korobkov's categorization, migration to Russia is frequently politically or ethnically motivated, although economic reasons offer a viable alternative in certain cases.

description: Asymptotic normalization coefficients (ANC) determine the overall normalization of cross sections of peripheral radiative capture reactions. In the present paper, we treat the ANC $C$ for the virtual decay $^{16}$O$(0^+; 6.05$ MeV)$\to α+^{12}$C(g.s.), the known values of which are characterized by a large spread $(0.29-1.65)\times 10^3$ fm$^{-1/2}$. The ANC $C$ is found by analytic continuation in the energy of the $α^{12}$C $s$-wave scattering amplitude, known from the phase-shift analysis of experimental data, to the pole corresponding to the $^{16}$O bound state and lying in the unphysical region of negative energies. To determine $C$, two different methods of analytic continuation are used. In the first method, the scattering data are approximated by the sum of polynomials in energy in the physical region and then extrapolated to the pole. The best way of extrapolation is chosen on the basis of the exactly solvable model. Within the second approach, the ANC $C$ is found by solving the Schrödinger equation for the two-body $α^{12}$C potential, the parameters of which are selected from the requirement of the best description of the phase-shift analysis data at a fixed experimental binding energy of $^{16}$O$(0^+; 6.05$ MeV) in the $α+^{12}$C channel. The values of the ANC $C$ obtained within these two methods lie in the interval (886--1139) fm$^{-1/2}$.

description: Doubly special relativity (DSR) is an effective model for encoding quantum gravity in flat spacetime. To incorporate DSR into general relativity, one could use "Gravity's rainbow", where the spacetime background felt by a test particle would depend on its energy. In this scenario, one could rewrite the rainbow metric $g_{μν}\left( E\right) $ in terms of some orthonormal frame fields and use the modified equivalence principle to determine the energy dependence of $g_{μν}\left( E\right) $. Obviously, the form of $g_{μν}\left( E\right) $ depends on the choice of the orthonormal frame. For a static black hole, there are two natural orthonormal frames, the static one hovering above it and freely falling one along geodesics. The cases with the static orthonormal frame have been extensively studied by many authors. The aim of this paper is to investigate properties of rainbow black holes in the scenario with the free-fall orthonormal frame. We first derive the metric of rainbow black holes and their Hawking temperatures in this free-fall scenario. Then, the thermodynamics of a rainbow Schwarzschild black hole is studied. Finally, we use the brick wall model to compute the thermal entropy of a massless scalar field near the horizon of a Schwarzschild rainbow black hole in this free-fall scenario.

description: We clarify the ground state phase diagram of the half-filled square-lattice Hubbard model with Rashba spin-orbit coupling (SOC) characterized by the spin-split energy bands due to broken inversion symmetry. Although the Rashba metals and insulating magnets have been studied well, the intermediate interaction strength of the system remained elusive due to the lack of appropriate theoretical tools to unbiasedly describe the large-scale magnetic structures. We complementarily apply four different methods; sine square deformed mean-field theory, random phase approximation, Luttinger-Tisza method, and density matrix embedding theory, and succeed in capturing the incommensurate spin density-wave (SDW) phases with very long spatial periods which were previously overlooked. The transition to the SDW phases from the metallic phase is driven by an unprecedented instability that nests the two parts of the Fermi surface carrying opposite spins. For large SOC, the spiral, stipe, and vortex phases are obtained, when the four Dirac points exist near the Fermi level and their whole linear dispersions nest by a wavelength $π$, opening a band gap. These two types of transition provide Fermiology that distinguishes the antisymmetric SOC systems, generating a variety of magnetic phases that start from the relatively weak correlation regime and continue to the strongly interacting limit.

description: Adaptive laboratory evolution (ALE) offers a potentially powerful method of genetic engineering for S. cerevisiae cell factories. One of the major limitations in ALE is the limited genetic diversity generation currently capable with traditional mutagenesis methods. The SCRaMbLE technique, outlined as a part of the Synthetic Yeast Genome Project (Sc 2.0) has the capacity to generate significant genetic diversity for use in ALE. Discussed here is the partial construction of synthetic chromosome XIV as a part of Sc 2.0, with successful integration of approximately 80 kilobases of synthetic DNA. Also presented here is the development of two biosensors for use in S. cerevisiae ALE experiments for the metabolites butanol and methionine, both of which are industrially significant chemicals. The butanol biosensor was based on the BmoRp transcription factor from Thauera butanovorans. Treatment of cells containing this biosensor with 5mM of butanol resulted in a 1.7 fold increase in GFP expression. The methionine biosensor was based on the S. cerevisiae MET17 promoter and has a dynamic range of 8.6 fold with the addition of 5mM methionine. Thorough characterisation of the components that comprise these biosensors suggest promising modifications that could improve their function and ultimately enable their use for ALE.

description: We train a network to identify jets with fractional dark decay (semi-visible jets) using the pattern of their low-level jet constituents, and explore the nature of the information used by the network by mapping it to a space of jet substructure observables. Semi-visible jets arise from dark matter particles which decay into a mixture of dark sector (invisible) and Standard Model (visible) particles. Such objects are challenging to identify due to the complex nature of jets and the alignment of the momentum imbalance from the dark particles with the jet axis, but such jets do not yet benefit from the construction of dedicated theoretically-motivated jet substructure observables. A deep network operating on jet constituents is used as a probe of the available information and indicates that classification power not captured by current high-level observables arises primarily from low-$p_\textrm{T}$ jet constituents.

In particular, we focus on van der Waals and charged-induced dipole interactions. As a result, we notice that, independently of the number of particles and interparticle interaction, the capture hyperradial distribution function follows a Fréchet distribution, a special type of the generalized extreme value distribution. Besides, we elaborate on the fundamentals of such universal feature using the general extreme value theory, thus, establishing a connection between extreme value theory and few-body physics.

The recent JWST Early Release Observations of this poorly known region of the sky have revealed numerous point-like sources within and surrounding their host galaxies, undetected in the shallower HST images. We use JWST multiband photometry and the lensing model of this galaxy cluster to estimate the intrinsic sizes and magnitudes of the stellar clumps. We derive optical restframe effective radii from $<$10 to 100s pc and masses ranging from $\sim10^5$ to $10^9$ M$_{\odot}$, overlapping with massive star clusters in the local universe. The ages range from 1 Myr to 1 Gyr. We compare the crossing time to the age of the clumps and determine that between 45 and 60 % of the detected clumps are consistent with being gravitationally bound. The lack of Gyr old clumps suggest that the dissolution time scales are shorter than 1 Gyr. We see a significant increase in the luminosity (mass) surface density of the clumps with redshift. Clumps in galaxies at the reionisation era have stellar densities higher than massive clusters in the local universe. We zoom-in into single galaxies at redshift $<6$ and find for two galaxies, the Sparkler and the Firework, that their star clusters/clumps show distinctive colour distributions and location surrounding their host galaxy that are compatible with being accredited or formed during merger events. The ages of some of the compact clusters are between 1 and 4 Gyr, e.g., globular cluster precursors formed around 9-12 Gyr ago. Our study, conducted on a small sample of galaxies, shows the potential of JWST observations for understanding the conditions under which star clusters form in rapidly evolving galaxies.

Exploring the Association between Executive Function and Incisor Trauma: A Pilot Study
Creators: name: Nyquist, Jillian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Objectives: To explore the relationship between executive function, as assessed by the Behavior Rating Inventory of Executive Function Parent Form Questionnaire (BRIEF®), and incisor trauma in the mixed dentition. Second, to assess other risk factors such as malocclusion, medical/dental history, and daily activities. Methods: This pilot study included 2 groups: a test group with history of incisor trauma (n=28) and a control group (n=30) with no history of incisor trauma. Subjects’ parents completed the BRIEF® that was scored to assess their child’s level of executive function, while a clinical examination was performed to assess subjects’ occlusal relationships. Parents completed a customized questionnaire regarding their child’s medical history and daily activities. The BRIEF® scores, occlusal characteristics, medical history, and reported daily activities were analyzed to determine if there was a significant difference between the test and control groups using a Fisher Exact and unpaired t-tests. Level of significance was set at 0.05. Results: There was a statistically significant difference between the groups with respect to AP dental relationship (p=0.01), with the trauma group having a greater percentage of participants with a Class II molar and canine relationship. There was no significant difference between groups with respect to mean BRIEF® t-scores within any of the individual subscales, indices, or Global Executive Composite. However, there was a statistically significant difference with respect to the percentage of subjects with clinically significant (≥65) BRIEF® t-scores within the Inhibit (p=0.05) and Emotional Control (p=0.02) subscales and Behavioral Regulation Index (p=0.02). There were no statistically significant differences between groups with respect to age, gender, overbite, overjet, medical history, BMI, or reported daily activities. Conclusion: Those with a Class II relationship are at greater risk for incisor injury, as well as those who are more involved in outdoor activities. There appears to be a link between certain specific executive dysfunctions (i.e. impulsivity and emotional control) and incisor trauma. A larger sample is needed to further investigate the relationship between the multidimensional Executive Function Disorder and incisor trauma.

description: Glykane aus exokrinen Drüsen stellen ein Schutzsystem der Schleimhautoberflächen dar, indem sie an mikrobielle Adhäsine binden und dadurch Einfluß auf die mikrobielle Besiedelung und Invasion des Wirtes nehmen. 11 Patienten mit rasch fortschreitender Parodontitis (RPP) wurde über jeweils 20 Minuten in Ruhe und unter adrenerger Belastung Speichel aus den großen Speicheldrüsen entnommen und in einem kompetitiven Lektinbindungsinhibitionstest auf die Bindungsfähigkeit an 8 verschiedene Planzenlektine untersucht. Patienten mit RPP zeigen ein anderes Verteilungsmuster der antiadhäsiven Glycane als die Kontrollgruppe. Sie zernieren u.a. aus den Unterkieferdrüsen konstant signifikant mehr Glykane mit endständigen Mannosegruppen, aus der Parotis dagegen nur unter adrenerger Stimulation. Dies zeigt die unterschiedliche Funktion der Drüsen bei der Beeinflussung des Milieus in der Mundhöhle als auch einen unterschiedlichen Erregungszustand des Schleimhautschutzsystems bei Erkrankten und Kontrollen. Aus den Ergebnissen können sich diagnostische Aspekte für das Risiko und den Aktivitätszustand einer parodontalen Erkrankung ergeben.
description: Glycans from exocrine glands create a defense system of the mucosal surfaces by binding to microbial adhesins and interfering with colonisation and invasion of the host. Saliva from 11 patients with rapidly progressive periodontitis (RPP) was collected over a period of 20 minutes each in rest and during adrenergic stimulation. The samples were tested for binding properties to 8 different plant lectins by a competitive lectin binding inhibition test. A pattern of antiadhesive glycans different from the control group is secreted in patients with RPP. The latter constantly secrete significantly more glycans with terminal mannose from the mandibular glands. In the parotis this is only the case during adrenergic stimulation. This demonstrates the different purpose of the glands in maintaining the oral milieu as well as different states of activity of the mucosal defense system in RPP patients and controls. Diagnostic aspects for risk and activity of periodontal diseases can be drawn from these findings.

description: The quantum chromodynamics axion with a decay constant near the Grand Unification (GUT) scale has an ultralight mass near a neV. We show, however, that axion-like particles with masses near the keV - PeV range with GUT-scale decay constants are also well motivated in that they naturally arise from axiverse theories with dark non-abelian gauge groups. We demonstrate that the correct dark matter abundance may be achieved by the heavy axions in these models through the misalignment mechanism in combination with a period of early matter domination from the long-lived dark glueballs of the same gauge group. Heavy axion dark matter may decay to two photons, yielding mono-energetic electromagnetic signatures that may be detectable by current or next-generation space-based telescopes. We project the sensitivity of next-generation telescopes including $\textit {Athena,}$ AMEGO, and e-ASTROGAM to such decaying axion dark matter. If the dark sector contains multiple confining gauge groups, then the observed primordial baryon asymmetry may also be achieved in this scenario through spontaneous baryogenesis. We present explicit orbifold constructions where the dark gauge groups unify with the SM at the GUT scale and axions emerge as the fifth components of dark gauge fields with bulk Chern-Simons terms.

description: We demonstrate an intense, continuous cold atom beam generated via post nozzle seeding of a supersonic helium jet with $^7$Li atoms. The nozzle is cooled to about 4.4 K to reduce the forward velocity of the atoms. The atomic beam is brought to a focus 175 cm from the nozzle by a 10 cm bore diameter magnetic hexapole lens. Absorption and fluorescence imaging of the focus show a flux of $2.3(4) \times 10^{12}$ atoms/s, brightness of $4.1(7)\times 10^{19}$ $\textrm{m}^{-2}\textrm{s}^{-1}\textrm{sr}^{-1}$, forward velocity of 211(2) m/s, and longitudinal temperature of 7(3) mK. Results agree with a Monte Carlo simulation of the seeding dynamics and a particle tracing simulation of the atom lens. We project that 10 times higher flux would be possible with improved vacuum system design. Our method should provide a useful high-brightness source for atom-optical and other atomic and molecular physics applications.

description: We study if periodic driving of a model with a quasiperiodic potential can generate interesting Floquet phases which have no counterparts in the static model. Specifically, we consider the Aubry-André model which is a one-dimensional time-independent model with an on-site quasiperiodic potential $V_0$ and a nearest-neighbor hopping amplitude which is taken to have a staggered form. We add a uniform hopping amplitude which varies periodically in time with a frequency $ω$. Unlike the static Aubry-André model which has a simple phase diagram with only two phases (only extended or only localized states), we find that the driven model has four possible phases: a phase with only extended states, a phase with multiple mobility gaps separating different quasienergy bands, a mixed phase with coexisting extended, multifractal, and localized states, and a phase with only localized states. The multifractal states have generalized inverse participation ratios which scale with the system size with exponents which are different from the values for both extended and localized states. In addition, we observe intricate re-entrant transitions between the different kinds of states when $ω$ and $V_0$ are varied. In the limit of high frequency and large driving amplitude, we find that the Floquet quasienergies match the energies of the undriven system, but the Floquet eigenstates are much more extended. We also study the spreading of a one-particle wave packet and find that it is always ballistic but the ballistic velocity varies significantly with the system parameters, sometimes showing a non-monotonic dependence on $V_0$ which does not occur in the static model. We conclude that the interplay of quasiperiodic potential and driving produces a rich phase diagram which does not appear in the static model.

description: Based on the Lefschetz thimble formulation of path-integration, we analyze the (0+1) dimensional Thirring model at finite chemical potentials and perform hybrid Monte Carlo (HMC) simulations. We adopt the lattice action defined with the staggered fermion and a compact link field for the auxiliary vector field. We firstly locate the critical points (saddle points) of the gradient flows within the subspace of time-independent (complex) link field, and study the thiemble structure and the Stokes phenomenon to identify the thimbles which contribute to the path-integral. Then, we perform HMC simulations on the single dominant thimble and compare the results to the exact solution. The numerical results are in agreement with the exact ones in small and large chemical potential regions, while they show some deviation in the crossover region in the chemical potential. We also comment on the necessity of the contributions from multiple thimbles in the crossover region.
