description: In two-beam magneto-photoluminescence spectra of a two-dimensional valence hole gas we identify the three-level energy spectrum of a free positive trion with a field-induced singlet-triplet transition. The recombination spectrum of acceptor-bound trions is also detected, including a cyclotron replica corresponding to the hole shake-up process. The emergence of a shake-up peak at low temperature is shown to be a sensitive probe of the presence of a small number of impurities inside the high-mobility quantum well, and its relative position is directly related to the hole cyclotron mass.

description: There are known two distinct types of the integer quantum Hall effect. One is the conventional quantum Hall effect, characteristic of two-dimensional semiconductor systems, and the other is its relativistic counterpart recently observed in graphene, where charge carriers mimic Dirac fermions characterized by Berry's phase pi, which results in a shifted positions of Hall plateaus. Here we report a third type of the integer quantum Hall effect. Charge carriers in bilayer graphene have a parabolic energy spectrum but are chiral and exhibit Berry's phase 2pi affecting their quantum dynamics. The Landau quantization of these fermions results in plateaus in Hall conductivity at standard integer positions but the last (zero-level) plateau is missing. The zero-level anomaly is accompanied by metallic conductivity in the limit of low concentrations and high magnetic fields, in stark contrast to the conventional, insulating behavior in this regime. The revealed chiral fermions have no known analogues and present an intriguing case for quantum-mechanical studies.

Exploring Residual Gauge Symmetry Breaking

Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: Simulations of pure-gauge SU(2) lattice gauge theory are performed in the minimal Coulomb gauge. This leaves a residual or remnant gauge symmetry still active which is global in three directions but still local in one. Using averaged fourth-dimension pointing links as a spin-like order parameter, the remnant symmetry appears to undergo spontaneous symmetry breaking at around $β= 2.6$. Both the Binder cumulant and the magnetization itself exhibit crossings in this region using lattices up to $20^4$, and a susceptibility peak is also observed. Finite size scaling indicates a weak first-order transition. The symmetry breaking is also observed to take place in the fundamental-adjoint plane, and is coincident with the strong first-order transition that exists there at large $β_{\rm{adjoint}}$. This provides confirmation that this phase transition is a symmetry-breaking transition. A well-known theorem concerning the instantaneous Coulomb potential has previously proven that a transition where such a Coulomb-gauge remnant symmetry breaks is necessarily deconfining.

description: We reconsider baryon stopping in relativistic heavy-ion collisions in a nonequilibrium-statistical framework. The approach combines earlier formulations based on quantum chromodynamics with a relativistic diffusion model through a suitably derived fluctuation-dissipation relation, thus allowing for a fully time-dependent theory that is consistent with QCD. We use an existing framework for relativistic stochastic processes in spacetime that are Markovian in phase space, and adapt it to derive a Fokker-Planck equation in rapidity space, which is solved numerically. The time evolution of the net-proton distribution function in rapidity space agrees with stopping data from the CERN Super Proton Synchrotron and the BNL Relativistic Heavy Ion Collider.

description: We report on in situ low-temperature (4 K) scanning tunneling microscope measurements of atomic and electronic structures of the cleaved surfaces of an alkali-based kagome metal RbV$_3$Sb$_5$ single crystals. We find that the dominant pristine surface exhibits Rb-1x1 structure, in which a unique unidirectional $\sqrt{3}a_0$ charge order is discovered. As the sample temperature slightly rises, Rb-$\sqrt{3}$x1 and Rb-$\sqrt{3}$x$\sqrt{3}$ reconstructions form due to desorption of surface Rb atoms. Our conductance mapping results demonstrate that Rb desorption not only gives rise to hole doping, but also renormalizes the electronic band structures. Surprisingly, we find a ubiquitous gap opening near the Fermi level in tunneling spectra on all the surfaces despite their large differences of hole-carrier concentration, indicating an orbital-selective band reconstruction in RbV$_3$Sb$_5$.

description: The present paper deals with the Cauchy problem of a multi-dimensional non-conservative viscous compressible two-fluid system. We first study the well-posedness of the model in spaces with critical regularity indices with respect to the scaling of the associated equations. In the functional setting as close as possible to the physical energy spaces, we prove the unique global solvability of strong solutions close to a stable equilibrium state. Furthermore, under a mild additional decay assumption involving only the low frequencies of the data, we establish the time decay rates for the constructed global solutions. The proof relies on an application of Fourier analysis to a complicated parabolic-hyperbolic system, and on a refined time-weighted inequality.

description: The analysis of the APOGEE DR16 data suggests the existence of a clear distinction between two sequences of disc stars at different Galactocentric distances in the [$α$/Fe] vs. [Fe/H] abundance ratio space: the so-called high-$α$ sequence, classically associated to an old population of stars in the thick disc, and the low-$α$ sequence, which mostly comprises relatively young stars in the thin disc. We perform a Bayesian analysis based on a Markov Chain Monte Carlo method to constrain a multi-zone two-infall chemical evolution model designed for regions at different Galactocentric distances using measured chemical abundances from the APOGEE DR16 sample. An inside-out formation of the Galaxy disc naturally emerges from the best fit of our two-infall chemical-evolution model to APOGEE-DR16: inner Galactic regions are assembled on shorter time-scales compared to the external ones. In the outer disc (with radii $R>6$ kpc), the chemical dilution due to a late accretion event of gas with primordial chemical composition is the main driver of the [Mg/Fe] vs. [Fe/H] abundance pattern in the low-$α$ sequence. In the inner disc, in the framework of the two-infall model, we confirm the presence of an enriched gas infall in the low-$α$ phase as suggested by chemo-dynamical models. Our Bayesian analysis of the recent APOGEE DR16 data suggests a significant delay time, ranging from $\sim$3.0 to 4.7 Gyr, between the first and second gas infall events for all the analyzed Galactocentric regions. Our results propose a clear interpretation of the [Mg/Fe] vs. [Fe/H] relations along the Galactic discs. The signatures of a delayed gas-rich merger which gives rise to a hiatus in the star formation history of the Galaxy are impressed in the [Mg/Fe] vs. [Fe/H] relation, determining how the low-$α$ stars are distributed in the abundance space at different Galactocentric distances.

The physical and chemical characteristics of kimberlite
Creators: name: Howe, Diane Joan
Publisher: name: University of British Columbia
Year: 2009

description: A detailed study of the physical and chemical characteristics of kimberlite fines provided the basis for this study which was to determine the factors that govern the flocculation processes. These studies showed that there are many physical and chemical characteristics which are similar and many which differ between the kimberlite samples. The mineralogical study showed that the type of minerals present were the same for each pipe, however their modal distribution varied. This difference is related to the type and intensity of alteration and the subsequent formation of clay-type minerals. The presence or absence of these alteration minerals also accounts for the differences found in the particle size distributions, in the surface areas, in the cation exchange capacities and densities. The zeta potential was found to be similar, with ranges between -15 to -35 mV, between the samples. Tests also showed the zeta potential could be further reduced by the addition of a Mg2 + ion. This reduction in zeta potential did cause some of the pipes to coagulate and settle. Although no one variable could be found, flocculant preference of the individual kimberhte samples appears to be related to the interaction of particle and polymer as a function of solution chemistry. It is postulated that the dissolution of magnesium bearing minerals (olivine) play a significant role. The dissolution of olivine increases the concentration of Mg2 + in solution thus promoting the attraction between particles and between the particle and polymer. In fact, chemical leach tests showed that Mg2 + and Ca 2 + were readily leached into solution, albeit not all pipes leached these ions at the same rate. Values of up to pH 9.5 can be accounted for by the dissolution of olivine. Alkaline pH's >9.5 are assumed to be the result of the formation of calcium hydroxide after the magnesium ion precipitates out of solution as Mg(OH)2. Pipes which produce a very high pH therefore do not have the Mg2 + ion readily available in solution to act as a coagulant. Coincidentally, these pipes required the addition of a coagulant to promote flocculation and a produce a clear supernatant.

description: The IRDC SDC335.579-0.292 (SDC335) is a massive star-forming cloud found to be globally collapsing towards one of the most massive star forming cores in the Galaxy. SDC335 hosts three high-mass protostellar objects at early stages of their evolution and archival ALMA Cycle 0 data indicate the presence of at least one molecular outflow in the region. Observations of molecular outflows from massive protostellar objects allow us to estimate the accretion rates of the protostars as well as to assess the disruptive impact that stars have on their natal clouds. The aim of this work is to identify and analyse the properties of the protostellar-driven molecular outflows within SDC335 and use these outflows to help refine the properties of the protostars. We imaged the molecular outflows in SDC335 using new data from the ATCA of SiO and Class I CH$_3$OH maser emission (~3 arcsec) alongside observations of four CO transitions made with APEX and archival ALMA CO, $^{13}$CO (~1 arcsec), and HNC data. We introduced a generalised argument to constrain outflow inclination angles based on observed outflow properties. We used the properties of each outflow to infer the accretion rates on the protostellar sources driving them and to deduce the evolutionary characteristics of the sources. We identify three molecular outflows in SDC335, one associated with each of the known compact HII regions. The outflow properties show that the SDC335 protostars are in the early stages (Class 0) of their evolution, with the potential to form stars in excess of 50 M$_{\odot}$. The measured total accretion rate onto the protostars is $1.4(\pm 0.1) \times 10^{-3}$M$_{\odot}$ yr$^{-1}$, comparable to the total mass infall rate toward the cloud centre on parsec scales of 2.5$(\pm 1.0) \times 10^{-3}$M$_{\odot}$ yr$^{-1}$, suggesting a near-continuous flow of material from cloud to core scales.

These field theories emerge at low energies, after a twisted compactification of a family of five dimensional ${\cal N}=2$ SCFTs on hyperbolic spaces. The holographic flows across dimensions are explicitly computed. We also discuss a family of SUSY breaking backgrounds, dual to a QCD-like quiver with massive (bi)fundamental matter. Some field theoretical observables are computed for these theories at the fixed points and along the flow.

description: The recent accessibility of high quality, charge neutral monolayer transition metal dichalcogenides with narrow exciton linewidths at the homogeneous limit provides an ideal platform to study excitonic many-body interactions. In particular, the possibility to manipulate coherent exciton-exciton interactions, which govern the ultrafast nonlinear optical response, by applying an external magnetic field has not been considered so far. We address this discrepancy by presenting a nonlinear microscopic theory in the coherent limit for optical excitations in the presence of out-of-plane, in-plane, and tilted magnetic fields. Specifically, we explore the magnetic-field-induced exciton and biexciton fine structure and calculate their oscillator strengths based on a Heisenberg equations of motion formalism. Our microscopic evaluations of pump-probe spectra allow to interpret and predict coherent signatures in future wave-mixing experiments.

description: Italian National Committee for Food Safety (CNSA) opinion of 15 JULY 2020 on Modified mycotoxins: elements for risk assessment and uncertainty characterization Modified mycotoxins (also called masked mycotoxins) are metabolites of mycotoxins that can be of different origins, since they can be produced: (a) by the fungus itself, diffusing them in the host; (b) by metabolism in plants, animals and humans; (c) during food processing. Modified mycotoxins are mainly products of fusariotoxins, which are priority contaminants in the food chain, due to their wide diffusion and relevant toxicants: zearalenone, deoxynivalenol, trichothecenes and fumonisins. Currently, there is no sound evidence available to assess if masked mycotoxins have lower, higher or different potency than parent mycotoxins. In addition, the lack of analytical standards and the variety of molecules represent a major limitation in identifying and precisely quantifying modified mycotoxins. Therefore, risk assessment of these mycotoxins suffers from significant uncertainties. Despite these uncertainties, there are indications that modified mycotoxins could have additive effects with their corresponding parent mycotoxin, thus contributing to toxic effects. Similar considerations underpin the precautionary approach adopted by EFSA in its opinions on modified mycotoxins published so far. The Food Safety Section of CNSA underlines the importance and current relevance of this issue, due to the high toxicity of mycotoxins, as well as to the fact that climate change might be a favourable factor for their production and the resulting human exposure. Therefore, the Food Safety Section of CNSA calls for an adequate financing of scientific studies with broad involvement of Bodies and Institutes, in order to have, in the short term, the elements needed to perform an effective assessment of consumer exposure and potential health risks.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We apply a two-particle semi-analytic approach to a single Anderson impurity attached to two biased metallic leads. The theory is based on reduced parquet equations justified in critical regions of singularities in the Bethe-Salpeter equations. It offers a way to treat one-particle and two-particle thermodynamic and spectral quantities on the same footing. The two-particle vertices are appropriately renormalized so that spurious transitions into the magnetic state of the weak-coupling approximations are suppressed. The unphysical hysteresis loop in the current-voltage characteristics is thereby eliminated. Furthermore, in the linear response regime, we qualitatively reproduce the three transport regimes with the increasing temperature: from the Kondo resonant tunneling through the Coulomb blockade regime up to a sequential tunneling regime. Far from equilibrium, we find that the bias plays a similar role as the temperature in destroying the Kondo resonant peak when the corresponding energy scale is comparable with the Kondo temperature. Besides that, the applied voltage in low bias is shown to develop spectral peaks around the lead chemical potentials as observed in previous theoretical and experimental studies.

This is a first step towards a classification of pointed Hopf algebras with group of group-likes isomorphic to one of these groups. As a by-product of the techniques developed in this work, we prove that there is no non-trivial finite-dimensional pointed Hopf algebra over the Mathieu groups $M_{20}$ and $M_{21}=\mathbf{PSL}(3,4)$.

description: We report the validation of a recently proposed infrared selection criterion for symbiotic stars (SySts). Spectroscopic data were obtained for seven candidates, selected from the SySt candidates of Akras et al. (2019, MNRAS, 483, 5077) by employing the new supplementary infrared selection criterion for SySts in the VST/OmegaCAM Photometric H-Alpha Survey (VPHAS+). Five of them turned out to be genuine SySts after the detection of H$α$, He II and [O III] emission lines as well as TiO molecular bands. The characteristic O VI Raman-scattered line is also detected in one of these SySts. According to their infrared colours and optical spectra, all five newly discovered SySts are classified as S-type. The high rate of true SySts detections of this work demonstrates that the combination of the H$α$-emission and the new infrared criterion improves the selection of target lists for follow-up observations by minimizing the number of contaminants and optimizing the observing time.

A particular solution with approximately flat rotation curve is discussed in some detail. We find that simple Newtonian arguments overestimate the amount of matter needed to explain these curves by more than 30%. The crucial insight gained by this model is that the Newtonian approximation breaks down globally, even though it is valid locally everywhere. No conflict with solar system tests arises.

description: There exist several classes of theories beyond the Standard Model which contain massive spin-1 color octets, generically called "colorons". Indeed we argue that colorons inevitably appear in the spectrum whenever new colored particles feel an additional confining force. Colorons are distinctive at hadron colliders as this is the only environment in which they can be resonantly produced. In the simplest models we show that the coloron naturally decays to multijets via secondary resonances, which can be consistent with all existing bounds, even for colorons as light as a few hundred GeV. We perform representative case studies and show that a search in the four-jet channel at the Tevatron has strong signal significance, while the LHC faces formidable challenges for such a search.

Keyword spotting is commonly used in smart speakers to listen for wake words, and adaptive control is used in robotic applications to adapt to unknown dynamics in an online fashion. We highlight the benefit of a multiply accumulate (MAC) array in the SpiNNaker 2 prototype which is ordinarily used in rate-based machine learning networks when employed in a neuromorphic, spiking context. In addition, the same benchmark tasks have been implemented on the Loihi neuromorphic chip, giving a side-by-side comparison regarding power consumption and computation time. While Loihi shows better efficiency when less complicated vector-matrix multiplication is involved, with the MAC array, the SpiNNaker 2 prototype shows better efficiency when high dimensional vector-matrix multiplication is involved.

description: This paper proposes two algorithms, namely "back-tracking" and "history following", to reach consensus in case of communication loss for a network of distributed agents with switching topologies. To reach consensus in distributed control, considered communication topology forms a strongly connected graph. The graph is no more strongly connected whenever an agent loses communication.Whenever an agent loses communication, the topology is no more strongly connected. The proposed back-tracking algorithm makes sure that the agent backtracks its position unless the communication is reestablished, and path is changed to reach consensus. In history following, the agents use their memory and move towards previous consensus point until the communication is regained. Upon regaining communication, a new consensus point is calculated depending on the current positions of the agents and they change their trajectories accordingly. Simulation results, for a network of six agents, show that when the agents follow the previous history, the average consensus time is less than that of back-tracking. However, situation may arise in history following where a false notion of reaching consensus makes one of the agents stop at a point near to the actual consensus point. An obstacle avoidance algorithm is integrated with the proposed algorithms to avoid collisions. Hardware implementation for a three robots system shows the effectiveness of the algorithms.

The Narrowing of Charge Balance Function and Hadronization Time in Relativistic Heavy Ion Collisions
Creators: name: Jiaxin, Du

description: The widths of charge balance function in high energy hadron-hadron and relativistic heavy ion collisions are studied using the Monte Carlo generators PYTHIA and AMPT, respectively. The narrowing of balance function as the increase of multiplicity is found in both cases. The mean parton-freeze-out time of a heavy-ion-collision event is used as the characteristic hadronization time of the event. It turns out that for a fixed multiplicity interval the width of balance function is consistent with being independent of hadronization time.

description: This work considers a two-dimensional artificial triangular anti-dot lattice (TAL); a semiconductor based artificial crystal hosting Dirac cones, flat bands and Fermi surface nesting. All such single particle features have dramatic implications for the emergent correlated phases. This work predominantly focuses on the existence of a robust flatband and enumerates the possible correlated phases that follow. We find that the flatband is generated, in the single-particle theory, when charges align themselves along a kagome lattice with the same period as the TAL. The correlated phases are studied using complementary techniques of expansions in strong and weak Coulomb interaction. Our microscopic modelling shows that for the purpose of generating strongly correlated phases, hole doped TALs have significant advantages over electron doped.

description: D. emarginata (Nees, 1834): This species looks very similar to D. maetoi Fernandez-Triana & Shimizu sp. nov. The propodeum and T2 are mostly sculptured, whereas in D. maetoi the propodeum is only sculptured around the areola, and T2 is only sculptured around margins. T1 is slightly thicker in D. emarginata (T1 length 1.4 times its width at posterior margin, whereas in D. maetoi is 1.5–1.7 times). D. emarginata is a solitary parasitoid whereas D. maetoi is gregarious.

description: In a recent article (Phys. Rev. B 71, 224402 (2005)), Safonov and Bertram claim "inconsistent" results can occur when applying the "Callen-Welton fluctuation dissipation theorem" to magnetic systems with dissipation. This author strongly disputes these claims, and instead will show that the inconsistencies claimed by Safonov and Bertram stem solely from a failure to correctly complete a linear transformation of variables, and a concomitant invalid application of well known fluctuation dissipation relations. When used correctly, such fluctuation-dissipation relations most certainly will apply to magnetic (or other physical) systems with dissipation.

Muonium formation and diffusion in cryocrystals
Creators: name: Morris, Gerald D.
Publisher: name: University of British Columbia
Year: 2009

description: Energetic positive muons stopping in insulators often form the hydrogen-like neutral atom muonium by capturing an electron from the stopping medium. In this thesis it is shown that some of this muonium is formed by free electrons, produced along the muon's radiolysis track, diffusing to the muon, and subsequently forming muonium. Electron transport properties of the lattice play a role in delayed muonium formation in these solids. Application of an electric field along the initial muon momentum reveals a strong anisotropy of the spatial distribution of electrons in the vicinity of the muon, implying that the muon's direction of motion during thermalization is not completely lost by multiple scattering. Estimates of the initial electron-muon separation and muonium formation time are given. Diffusion of muonium in cryocrystals has been studied with both transverse and longitudinal field muon spin relaxation techniques. Experimental results are compared to the theory of quantum tunnelling diffusion. In solid nitrogen at temperatures much smaller than the Debye temperature of the lattice, the data and theory are in good agreement, with a temperature dependence approaching the T⁷ law predicted by the theory of twophonon quantum diffusion. At higher temperatures the agreement is qualitative only, but does show a key feature of two-phonon quantum tunnelling diffusion - a rapid increase in hop rate as temperature decreases due to the reduction of the phonon scattering rate. Muonium in solid Xe is an extreme case of a light interstitial atom in a heavy lattice. This system was chosen to provide an example of tunnelling diffusion at relatively high temperatures where lattice dynamics could be expected to play a role in determining the muonium hop rate. The hop rate of muonium atoms in solid Xe was measured over a

description: Im Zeitraum Juni 2010 bis April 2011 wurde in Berlin eine repräsentative Befragung von Jugendlichen der neunten Jahrgangsstufe im Rahmen des Schulunterrichts durchgeführt. Im Fokus der Untersuchung standen die Verbreitung und die Bedingungsfaktoren des delinquenten Verhaltens von Jugendlichen. Eine solche Untersuchung erschien deshalb notwendig, weil sowohl in der Polizeilichen Kriminalstatistik als auch in der Medienöffentlichkeit der Eindruck erweckt wurde, dass Berlin ein Jugend-Gewaltproblem hat. Über eine Dunkelfeldbefragung sollten zusätzliche Informationen über das Thema Jugendgewalt gesammelt werden, die zugleich als Grundlage von Präventions- und Interventionsmaßnahmen dienen. Insgesamt konnten 3.167 Jugendliche der neunten Jahrgangsstufe befragt werden.

description: Using the relativistic impulse approximation with the Love-Franey \textsl{NN} scattering amplitude developed by Murdock and Horowitz, we investigate the low-energy (100 MeV$\leq E_{\mathrm{kin}}\leq 400$ MeV) behavior of the nucleon Dirac optical potential, the Schrödinger-equivalent potential, and the nuclear symmetry potential in isospin asymmetric nuclear matter. We find that the nuclear symmetry potential at fixed baryon density decreases with increasing nucleon energy. In particular, the nuclear symmetry potential at saturation density changes from positive to negative values at nucleon kinetic energy of about 200 MeV. Furthermore,the obtained energy and density dependence of the nuclear symmetry potential is consistent with those of the isospin- and momentum-dependent MDI interaction with $x=0$, which has been found to describe reasonably both the isospin diffusion data from heavy-ion collisions and the empirical neutron-skin thickness of $^{208} $Pb.
