description: We investigate the dynamics of matter and optical waves at the early stage of superradiant Rayleigh scattering from Bose-Einstein Condensates. Our analysis is within a spatially dependent quantum model which is capable of providing analytic solutions for the operators of interest. The predictions of the present model are compared to the predictions of a closely related mean field model, and we provide a procedure that allows one to calculate quantum expectation values by averaging over semiclassical solutions. The coherence properties of the outgoing scattered light are also analyzed, and it is shown that the corresponding correlation functions may provide detailed information about the internal dynamics of the system.

description: Quantum entanglement between the two $W$ bosons resulting from the decay of a Higgs boson may be investigated in the dilepton channel $H \to WW \to \ell ν\ell ν$ using laboratory-frame observables that only involve the charged leptons $\ell=e,μ$. The dilepton invariant mass distribution, already measured by the ATLAS and CMS Collaborations at the LHC, can be used to observe the quantum entanglement of the $WW$ pair with a statistical sensitivity of $7σ$ with Run 2 data, and of $6σ$ when including theoretical systematics. As a by-product, the relation between $W$ rest frame (four-dimensional) angular distributions, $H \to WW$ decay amplitudes, and spin correlation coefficients, is written down.

Toward ground-based detection of exoEarths. Spectral microvariability of exoplanet host stars

Publisher: name: Zenodo

description: The radial-velocity method is a plausible tool toward ground-based detection of Earth-like planets around solar-type stars. Instrumental precisions are approaching the required level but limitations remain in understanding the complexities of stellar atmospheric dynamics that modulate spectral-line displacements. Solar-type stars are covered by a million granules, each with velocities on order 2 km/s, producing full-disk jittering of the apparent radial velocity of perhaps 2 m/s. From 3D hydrodynamic modeling, time-variable stellar spectra can now be computed, showing correlated variability in different spectral-line parameters (Dravins et al., 2021ab). Blueshifted line components from hot granules in rising motion carry greater photon fluxes while steeper atmospheric gradients enhance local line-strengths. Dependences differ between high-excitation lines from ionized species and those from easily dissociated molecules. Observational calibration is enabled by the recent release of HARPS-N spectra of the Sun seen-as-a-star, where lines with specific astrophysical parameters can be examined for how their fluctuations correlate with excursions in radial velocity. Their calibration might allow to adjust low-noise observations of bright stars to attain their very accurate velocities. Dravins, Ludwig & Freytag: A&A 649, A16 (2021a); A&A 649, A17 (2021b)

description: The performance of modular, networked quantum technologies will be strongly dependent upon the quality of their quantum light-matter interconnects. Solid-state colour centres, and in particular T centres in silicon, offer competitive technological and commercial advantages as the basis for quantum networking technologies and distributed quantum computing. These newly rediscovered silicon defects offer direct telecommunications-band photonic emission, long-lived electron and nuclear spin qubits, and proven native integration into industry-standard, CMOS-compatible, silicon-on-insulator (SOI) photonic chips at scale. Here we demonstrate further levels of integration by characterizing T centre spin ensembles in single-mode waveguides in SOI. In addition to measuring long spin T_1 times, we report on the integrated centres' optical properties. We find that the narrow homogeneous linewidth of these waveguide-integrated emitters is already sufficiently low to predict the future success of remote spin-entangling protocols with only modest cavity Purcell enhancements. We show that further improvements may still be possible by measuring nearly lifetime-limited homogeneous linewidths in isotopically pure bulk crystals. In each case the measured linewidths are more than an order of magnitude lower than previously reported and further support the view that high-performance, large-scale distributed quantum technologies based upon T centres in silicon may be attainable in the near term.

description: We study the spectrum of multi-photon radiation off a fast quark in medium in the BDMPS/ASW approach. We reproduce the medium-induced one-photon radiation spectrum in dipole approximation, and go on to calculate the two-photon radiation in the Molière limit. We find that in this limit the LPM effect holds for medium-induced two-photon ladder emission.

Modeling Transit Dark Energy in $f(R, L_m)$-gravity

description: This research paper deals with a transit dark energy cosmological model in $f(R, L_{m})$-gravity with observational constraints. For this, we consider a flat FLRW space-time and have taken a cosmological cosntant-like parameter $β$ in our field equations. The model has two energy parameters~ $Ω_{m0}~ and~ Ω_{\beta0}$, which govern the mechanism of the universe, in particular its present accelerated phase. To make the model cope with the present observational scenario, we consider three types of observational data set: $46$ Hubble parameter data set, SNe Ia $715$ data sets of distance modulus and apparent magnitude, and $40$ datasets of SNe Ia Bined compilation in the redshift $0\leq z<1.7$. We have approximated the present values of the energy parameters by applying $R^{2}$ and $χ^{2}$-test in the observational and theoretical values of Hubble, distance modulus, and apparent magnitude parameters. Also, we have measured the approximate present values of cosmographic coefficients $\{H_{0}, q_{0}, j_{0}, s_{0}, l_{0}, m_{0}\}$. It is found that our approximated value-based model fits best with the observational module. We have found that as $t\to\infty$ (or $z\to 0$) then $\{q, j, s, l, m\}\to\{-1, 1, 1, 1, 1\}$. The cosmic age of the present universe is also approximated and comes up to the expectation. Our model shows a transit phase of the present accelerating universe with a deceleration in the past and has a transition point.

description: DC superconducting quantum interference devices (dc-SQUIDs) were fabricated in Co-doped BaFe2As2 epitaxial films on (La, Sr)(Al, Ta)O3 bicrystal substrates with 30deg misorientation angles. The 18 x 8 micro-meter^2 SQUID loop with an estimated inductance of 13 pH contained two 3 micro-meter wide grain boundary junctions. The voltage-flux characteristics clearly exhibited periodic modulations with deltaV = 1.4 micro-volt at 14 K, while the intrinsic flux noise of dc-SQUIDs was 7.8 x 10^-5 fai0/Hz^1/2 above 20 Hz. The rather high flux noise is mainly attributed to the small voltage modulation depth which results from the superconductor-normal metal-superconductor junction nature of the bicrystal grain boundary.
The splitting theorem for globally hyperbolic Lorentzian length spaces with non-negative timelike curvature

description: In this work, we prove a synthetic splitting theorem for globally hyperbolic Lorentzian length spaces with global non-negative timelike curvature containing a complete timelike line. Just like in the case of smooth spacetimes, we construct complete, timelike asymptotes which, via triangle comparison, can be shown to fit together to give timelike lines. To get a control on their behaviour, we introduce the notion of parallelity of timelike lines in the spirit of the splitting theorem for Alexandrov spaces and show that asymptotic lines are all parallel. This helps to establish a splitting of a neighbourhood of the given line. We then show that this neighbourhood has the timelike completeness property and is hence inextendible, which globalises the local result.

Exchanging stories : a narrative ethnography of immigrant seniors’ English language learning experiences.
Creators: name: Balyasnikova, Natalia
Publisher: name: University of British Columbia
Year: 2019

description: The growth of the ageing population worldwide has been noted as one of the “major forces shaping the 21st century” (World Health Organization, 2007, p. 6). Reflecting the trends of global demographics, Canadian census indicates that the proportion of seniors is rapidly growing across Canadian provinces (Statistics Canada, 2014). However, one peculiarity of the Canadian context is that the increased number of seniors can be in part attributed to immigration patterns. With many immigrant seniors arriving in Canada with little to no English, language learning support becomes a significant issue for research, educational practice, and seniors’ wellbeing. By drawing on the theoretical constructs of the contact zone and agency, this thesis examines the role of English language learning in the lives of ageing immigrants in Canada. Ten immigrant seniors participated in a customized language learning class in a community-based program, which was centered on narrative expression as the main pedagogical strategy. The participants were asked to create written and multimodal texts in response to a series of prompts about their language learning and use upon arrival in Canada. In addition, each of the participants was interviewed about their language learning experiences. Thematic analysis of written, spoken, and multimodal data suggests that senior adult language learners seek social connection through agentive undertakings of language learning. The oral and written narratives of the participants portray language learning as a way to grow social circles and work through experiences of racism, ageism, and linguicism. In addition, practices observed during the classroom-based ethnography support the use of narrative as a core pedagogical practice, and story-sharing as a strategy to facilitate language learning in community-based settings.

description: We demonstrate the generation of a strong mechanical squeezing in a dissipative optomechanical system by introducing a periodic modulation in the amplitude of a single-tone laser driving the system. The mechanical oscillator is quadratically coupled to the optical mode, which contributes to a strong squeezing exceeding the 3-dB standard quantum limit. The Bogoliubov mode of the mechanical oscillator also cools down to its ground state due to sideband cooling. We further optimize this ratio of sideband strengths to introduce enhanced squeezing. We also compare our results with the analytical (under adiabatic approximation) and the exact numerical solution. Even for a thermal occupancy of 10^4 phonons, mechanical squeezing beyond 3 dB and a strong optomechanical entanglement is observed.
Turbulence and turbulent mixing in natural fluids

description: Turbulence and turbulent mixing in natural fluids begins with big bang turbulence powered by spinning combustible combinations of Planck particles and Planck antiparticles. Particle prograde accretions on a spinning pair releases 42% of the particle rest mass energy to produce more fuel for turbulent combustion. Negative viscous stresses and negative turbulence stresses work against gravity, extracting mass-energy and space-time from the vacuum. Turbulence mixes cooling temperatures until strong-force viscous stresses freeze out turbulent mixing patterns as the first fossil turbulence. Cosmic microwave background temperature anisotropies show big bang turbulence fossils along with fossils of weak plasma turbulence triggered as plasma photon-viscous forces permit gravitational fragmentation on supercluster to galaxy mass scales. Turbulent morphologies and viscous-turbulent lengths appear as linear gas-proto-galaxy-clusters in the Hubble ultra-deep-field at z~7. Proto-galaxies fragment into Jeans-mass-clumps of primordial-gas-planets at decoupling: the dark matter of galaxies. Shortly after the plasma to gas transition, planet-mergers produce stars that explode on overfeeding to fertilize and distribute the first life.

description: The Fermi/LAT collaboration recently reported the detection of starburt galaxies in the high energy gamma-ray domain, as well as radio-loud narrow-line Seyfert 1 objects. Motivated by the presence of sources close to the location of composite starburst/Seyfert 2 galaxies in the first year Fermi/LAT catalogue, we aim at studying high energy gamma-ray emission from such objects, and at disentangling the emission of starburst and Seyfert activity. We analysed 1.6 years of Fermi/LAT data from NGC 1068 and NGC 4945, which count among the brightest Seyfert 2 galaxies. We search for potential variability of the high energy signal, and derive a spectrum of these sources. We also analyse public INTEGRAL IBIS/ISGRI data over the last seven years to derive their hard X-ray spectrum. We find an excess of high energy gamma-rays of 8.3 sigma and 9.2 sigma for 1FGL J0242.7+0007 and 1FGL J1305.4-4928, which are found to be consistent with the position of the Seyfert 2 galaxies NGC 1068 and NGC 4945, respectively. The energy spectrum of the sources can be described by a power law with a photon index of Gamma=2.31 \pm 0.13 for NGC 1068, while for NGC 4945, we obtain a photon index of Gamma=2.31 \pm 0.10. For both sources, we detect no significant variability nor any indication of a curvature of the spectrum. We discuss the origin of the high energy emission of these objects in the context of Seyfert or starburst activity. While the emission of NGC 4945 is consistent with starburst activity, that of NGC 1068 is an order of magnitude above expectations, suggesting dominant emission from the active nucleus. We show that a leptonic scenario can account for the multi-wavelength spectral energy distribution of NGC 1068.

description: Despite exciting progress in causal language models, the expressiveness of the representations is largely limited due to poor discrimination ability. To remedy this issue, we present ContraCLM, a novel contrastive learning framework at both token-level and sequence-level. We assess ContraCLM on a variety of downstream tasks. We show that ContraCLM enhances discrimination of the representations and bridges the gap with the encoder-only models, which makes causal language models better suited for tasks beyond language generation. Specifically, we attain $44\%$ relative improvement on the Semantic Textual Similarity tasks and $34\%$ on Code-to-Code Search tasks. Furthermore, by improving the expressiveness of the representations, ContraCLM also boosts the source code generation capability with $9\%$ relative improvement on execution accuracy on the HumanEval benchmark.

description: In this work, we solve the problem of developing the client part of a large hardware and software complex for managing electron microscopes. Within this task, we have analyzed various approaches of building client-side web applications and have selected the optimal framework. As a result of the work, an intuitive user interface was developed that helps scientists use electron microscopes without undergoing special training. It helps to view the results of the analysis in the form of tables and interactive graphs and to perform hardware equipment maintenance.

description: Superconducting traveling-wave parametric amplifiers are a promising amplification technology suitable for applications in submillimeter astronomy. Their implementation relies on the use of Floquet transmission lines in order to create strong stopbands to suppress undesired harmonics. In the design process, amplitude equations are used to predict their gain, operation frequency, and bandwidth. However, usual amplitude equations do not take into account the real and imaginary parts of the dispersion and characteristic impedance that results from the use of Floquet lines, hindering reliable design. In order to overcome this limitation, we have used the multiple-scales method to include those effects. We demonstrate that complex dispersion and characteristic impedance have a stark effect on the transmission line's gain, even suppressing it completely in certain cases. The equations presented here can, thus, guide to a better design and understanding of the properties of this kind of amplifiers.

description: The ghost for world-sheet reparametrization invariance is not a fundamental field in the pure spinor formalism. It is written as a combination of pure spinor variables which have conformal dimension two and such that it commutes with the BRST operator to give the world-sheet stress tensor. We show that the ghost variable defined in this way is nilpotent since the OPE of b with itself does not have singularities.

Saddle-node bifurcation of limit cycles in an epidemic model with two levels of awareness

description: In this paper we study the appearance of bifurcations of limit cycles in an epidemic model with two types of aware individuals. All the transition rates are constant except for the alerting decay rate of the most aware individuals and the rate of creation of the less aware individuals, which depend on the disease prevalence in a non-linear way. For the ODE model, the numerical computation of the limit cycles and the study of their stability are made by means of the Poincaré map. Moreover, sufficient conditions for the existence of an endemic equilibrium are also obtained. These conditions involve a rather natural relationship between the transmissibility of the disease and that of awareness. Finally, stochastic simulations of the model under a very low rate of imported cases are used to confirm the scenarios of bistability (endemic equilibrium and limit cycle) observed in the solutions of the ODE model.

description: Very recently the BaBar collaboration has put forward a claim that the X(3872) is not a 1^++ resonance, as most of the phenomenological work on the subject was relying on, but rather a 2^-+ one. We examine the consequences of this quantum number assignment for the solution of the X(3872) puzzle. The molecular interpretation appears less likely, and the conventional charmonium interpretation should be reconsidered. There are several well-known difficulties with this interpretation, to which we add a new one: the production cross section at CDF is predicted to be much smaller than that observed. We also confirm, using a relativistic string model, the conclusion from potential models that the mass of the state is not consistent with expectations. In the tetraquark interpretation the 2^-+ assignment implies a rich spectrum of partner states, although the X(3872) may be among the few which are narrow enough to be observable.

description: Quantum computers have the potential to bring forth a major breakthrough in scientific computing. The foreseen increase in computational efficiency offered by quantum computing is of such magnitude that, despite being in its infancy, it is already being coupled with traditional high-performance computing technology. Here, we give an overview of quantum computing, the present state of affairs, and future scenarios. Europe has a unique opportunity to create world-leading supercomputing infrastructures incorporating quantum technology, by capitalising on the established expertise of European HPC centres in conjunction with the emerging European quantum ecosystem. This requires dedicated and sustained funding for quantum hardware and software developments, as well as for education. In addition, coordinated efforts and support for early adoption of quantum computing in academia and industry are essential.

description: Numerous sources produce the ionization impact on the planetary atmosphere. The tropospheric cloudiness therewith is originated at such altitudes, which coincide with places of the maximum of the atmospheric ionization that caused by space radiation. Components of cosmic radiation, penetrating down to the stratospheric and tropospheric altitudes, produce in the first place the ionization of aerosols that brings to subsequent amplifying the activity of atmospheric vortices. The ionized aerosol constituent is of primary importance both in the initiation of plasma vortices and in the concentration of energy-mass by air vortices due to the humidity condensation. The ionization process is cascading, that causes the non-linear impact of penetrating rays, which amplifying with growing the air pollution. Various heterogeneities inside plasma subsystems provoke the random intensification of aperiodic electrostatic disturbances, which can exert a significant action on the development of vortices. Sometimes beaded lightning arises during thunderstorm. Using the approach of the Boltzmann kinetic equation, the characteristics of electrostatic oscillations for non-uniform plasma, are analytically derived. The analytical expressions are obtained for non-magnetized plasma. In the limits of the Earth's atmosphere, these solutions are strictly applicable to the origination of electrostatic modulations along the lines of force of the geomagnetic field and approximately applicable in cases, when the impact of the Earth's magnetic field is negligible. The explicit expressions are deduced both in the hot plasma approximation and in the cold plasma approximation. It is demonstrated that the formation of chain elements of discharge in hot inhomogeneous plasma is defined by the nonmonotonic distribution of charges and fields. At such conditions, the irregularities breaks up into a cellular structure.

description: Depression and anxiety disorders are the most prevalent classes of mental illness in youth and are associated with severe long-term impairment. Thus, a thorough understanding of factors contributing to the development of these disorders is paramount. Evidence indicates that maladaptive biological responses to stress increase risk for the onset of depression and anxiety, but the mechanisms underlying individual differences in stress responsivity are unclear. Importantly, evidence suggests that individual differences in cognitive disengagement biases, or difficulty disengaging from valenced material, may be associated with individual differences in biological responses to stress. The current study extends past research by investigating, for the first time, whether difficulty cognitively disengaging from valenced stimuli is associated with individual differences in biological responses to stress in a sample of preadolescents. A sample of 43 preadolescents completed two computer-based tasks to assess biases in both attentional disengagement and working memory disengagement. In addition, stress responsivity was indexed by levels of both cortisol and alpha-amylase in response to a psychosocial stressor, the Trier Social Stress Test for Children (TSST-C; Buske-Kirschbaum et al., 1997). It was hypothesized that disengagement biases for negative stimuli would be significantly associated with prolonged biological recovery from stress. Findings indicated that both attentional and working memory disengagement biases were associated with baseline levels of cortisol and alpha-amylase, and with the slope of biological recovery from stress; however, the direction of some findings were unexpected. In addition, working memory biases were associated with the slope of alpha-amylase reactivity to stress. The current results contribute to theoretical models of the relation between cognition and biological responses by identifying potential candidate cognitive mechanisms that are associated with individual differences in cortisol and alpha-amylase responses to stress. The current study also presents an important methodological advancement in the literature by examining the relative contribution of both attentional and working memory disengagement biases to the prediction of both neuroendocrine and autonomic nervous system responses to stress. Understanding the association between cognition and biological responses to stress may facilitate the development of personalized, transdiagnostic treatments for youth who show biological stress profiles that increase their risk of developing depression or anxiety.
