description: We provide further evidence for Smilga's conjecture that higher charges of integrable systems are suitable candidates for higher derivative theories that possess benign ghost sectors in their parameter space. As concrete examples we study the properties of the classical phase spaces for a number of affine Toda lattices theories related to different types of Kac-Moody algebras. We identify several types of scenarios for theories with higher charge Hamiltonians: some that possess oscillatory, divergent, benign oscillatory and benign divergent behaviour when ghost sectors are present in the quantum theory. No divergent behaviour was observed for which the trajectories reach a singularity in finite time. For theories based on particular representations for the Lie algebraic roots we found an extreme sensitivity towards the initial conditions governed by the Poisson bracket relations between the centre-of-mass coordinate and the charges.

description: Four out of the seven chapters of the Carnegie Report on the Balkan Wars were written by Pavel N. Miliukov, a Russian historian and deputy of the Russian parliament. During his long travels in the Balkans between the end of the 19th century and the First World War, Miliukov had fulfilled duties of a researcher, a journalist and a politician. Having lectured at the University of Sofia, he left Bulgaria to take part in archaeological expeditions in Macedonia. In liberal Russian newspapers, he later wrote regularly about the current political situations in South-Eastern Europe. As a historian, Miliukov backed up Bulgaria in the struggle over the Macedonian question by relying on ethnological reasons. As a journalist, he initially preferred the establishment of a Balkan union that included the Ottoman Empire and then advocated the formation of a Balkan federation against the Young Turks. As a politician, he defended the national interests of Russia at the Bosporus and Dardanelles, which also went hand in hand with a Bulgarian predominance in the Balkans. Contrary to Miliukov’s articles in newspapers or his speeches in the parliament, his contributions to the Carnegie Report miss analytical insights. Miliukov defended the Bulgarian position in the Balkans by condemning the Treaty of Bucharest, which was signed in the aftermath of the Second Balkan War, and regarding it as a source of new conflicts.

description: International Law and Conciliarist Internationalism under Pressure: Political Profiles of the Carnegie Men framing the Carnegie Report on the Balkan Wars c. 1914 and Beyond The Carnegie Report on the Balkan Wars could neither pacify the regional conflicts nor ban future ethnic violence. Yet it signifies a highly symptomatic moment in early 20th-century US Big Philanthropy. In order to assess its historical relevance, this article traces the report’s historical setting in contemporary US American political and legal debates from 1910 to the early 1920s. Two major features stand out: First, the report testifies to the contemporary programmatic creed and political leanings of its most renowned trustees – such as Elihu Root, James T. Shotwell, James Brown Scott and Nicholas Murray Butler – who envisioned an international world order based on increasingly professionalized international law. Most of them judicial experts, some of them staunch republican foreign policy elites, others more progressive intellectuals, they felt authorized to scientifically analyse and advise international diplomacy. Second, however, the Carnegie Men’s emphasis on law-based internationalism was no static endeavour. It rather succumbed to the turmoils of their time. Under the unfavourable auspices of World War I since 1914 and, even more so with the United States entering the war in 1917 and during the complicated peace negotiations in 1918/19, the philanthropic experiment of propagating a law-based vision of the world order was gradually transformed into a new version of conciliarist internationalism based on close cooperation with the new League of Nations in the early 1920s.

description: Accidental ground state degeneracies -- those not a consequence of global symmetries of the Hamiltonian -- are inevitably lifted by fluctuations, often leading to long-range order, a phenomenon known as "order-by-disorder" (ObD). The detection and characterization of ObD in real materials currently lacks clear, qualitative signatures that distinguish ObD from conventional energetic selection. We show that for order-by-thermal-disorder (ObTD) such a signature exists: a characteristic temperature dependence of the fluctuation-induced pseudo-Goldstone gap. We demonstrate this in a minimal two-dimensional model that exhibits ObTD, the ferromagnetic Heisenberg-compass model on a square lattice. Using spin-dynamics simulations and self-consistent mean-field calculations, we determine the pseudo-Goldstone gap, $Δ$, and show that at low temperatures it scales as the square root of temperature, $\sqrt{T} $. We establish that a power-law temperature dependence of the gap is a general consequence of ObTD, showing that all key features of this physics can be captured in a simple model of a particle moving in an effective potential generated by the fluctuation-induced free energy.

description: In radio interferometry, observed visibilities are intrinsically sampled at some interval in time and frequency. Modern interferometers are capable of producing data at very high time and frequency resolution; practical limits on storage and computation costs require that some form of data compression be imposed. The traditional form of compression is a simple averaging of the visibilities over coarser time and frequency bins. This has an undesired side effect: the resulting averaged visibilities "decorrelate", and do so differently depending on the baseline length and averaging interval. This translates into a non-trivial signature in the image domain known as "smearing", which manifests itself as an attenuation in amplitude towards off-centre sources. With the increasing fields of view and/or longer baselines employed in modern and future instruments, the trade-off between data rate and smearing becomes increasingly unfavourable. In this work we investigate alternative approaches to low-loss data compression. We show that averaging of the visibility data can be treated as a form of convolution by a boxcar-like window function, and that by employing alternative baseline-dependent window functions a more optimal interferometer smearing response may be induced. In particular, we show improved amplitude response over a chosen field of interest, and better attenuation of sources outside the field of interest. The main cost of this technique is a reduction in nominal sensitivity; we investigate the smearing vs. sensitivity trade-off, and show that in certain regimes a favourable compromise can be achieved. We show the application of this technique to simulated data from the Karl G. Jansky Very Large Array (VLA) and the European Very-long-baseline interferometry Network (EVN).

description: When a quantum state traverses a path, while being under the influence of a gauge potential, it acquires a geometric phase that is often more than just a scalar quantity. The variety of unitary transformations that can be realised by this form of parallel transport depends crucially on the number of particles involved in the evolution. Here, we introduce a particle-number threshold (PNT) that assesses a system's capabilities to perform purely geometric manipulations of quantum states. This threshold gives the minimal number of particles necessary to fully exploit a system's potential to generate non-Abelian geometric phases. Therefore, the PNT might be useful for evaluating the resource demands of a holonomic quantum computer. We benchmark our findings on bosonic systems relevant to linear and nonlinear quantum optics.

description: Relation-changing modal logics are extensions of the basic modal logic that allow changes to the accessibility relation of a model during the evaluation of a formula. In particular, they are equipped with dynamic modalities that are able to delete, add, and swap edges in the model, both locally and globally. We provide translations from these logics to hybrid logic along with an implementation. In general, these logics are undecidable, but we use our translations to identify decidable fragments. We also compare the expressive power of relation-changing modal logics with hybrid logics.

The electron-phonon interaction with forward scattering peak is a relevant approach to high Tc superconductivity in FeSe films on SrTiO3 and TiO2

description: The theory of EPI with strong forward scattering peak (FSP)[1-3] is recently applied in [4-5] in studying high Tc(~100 K) in a FeSe grown on SrTiO3 [4] and TiO2 [6]. The EPI is due to a long-range dipolar electric field created by the high-energy oxygen vibrations (E0~90 meV) at the interface [4-5]. Besides obtaining new results we also correct some misleading results from the recent literature. We show that the mean-field critical temperature Tc0 is an interplay between the maximal pairing potential and the FSP-width qc. For Tc0~100 K the gap (G) is G~16 meV in agreement with ARPES experiments. We find that in leading order Tc0 is mass-independent and there is small oxygen isotope effect in next to leading order. In clean systems Tc0 for s-wave and d-wave pairing is degenerate but both are affected by non-magnetic impurities. The non-magnetic impurities are pair-weakening in the s-channel and pair-breaking in the d-channel. The normal state self-energy at the Fermi surface gives rise to the ARPES quasiparticle band at E=0 and to a replica band at Er=-E0(1+l(m))^1/2, respectively. The EPI coupling l(m), which enters the self-energy, is mass-dependent - the fact overlooked in the literature, makes at low energies the slope of the self-energy mass-dependent. The smallness of the oxygen isotope effect in Tc0 and its presence in the self-energy in FeSe films on SrTiO3 and TiO2 is a smoking-gun experiment for the application of the EPI-FSP theory to these systems. The EPI-FSP theory predicts a large number of low-laying pairing states (above the ground state) thus causing internal pair fluctuations. The latter reduce Tc0 additionally, by creating a pseudogap state for Tc

description: Coalescence of voids by internal necking is in most cases the last microscopic event related to ductile fracture and corresponds to a localized plastic flow between adjacent voids. Macroscopic load associated to the onset of coalescence is classically estimated based on limit analysis. However, a rigorous upper-bound mathematical expression for the limitload required for flat voids coalescence that remains finite for penny-shaped voids/cracks is still unavailable. Therefore, based on limit analysis, theoretical upper-bound estimates - both integral expression and closed-form formula - are obtained for the limit-load of cylindrical flat voids in cylindrical unit-cell subjected to boundary conditions allowing the assessment of coalescence, for axisymmetric stress state. These estimates, leading to finite limit-loads for pennyshaped cracks, are shown to be in very good agreement with numerical limit analysis, for both cylindrical and spheroidal voids. Approximate formula is also given for coalescence under combined tension and shear loading. These coalescence criteria can thus be used to predict onset of coalescence of voids by internal necking in ductile fracture modelling.

description: We describe an approach to optically trapping small, chemically stable molecules at cryogenic temperatures by buffer-gas loading a deep optical dipole trap. The ~10 K trap depth will be produced by a tightly-focused, 1064-nm cavity capable of reaching intensities of hundreds of GW/cm$^2$. Molecules will be directly buffer-gas loaded into the trap using a helium buffer gas at 1.5 K. The very far-off-resonant, quasielectrostatic trapping mechanism is insensitive to a molecule's internal state, energy level structure, and its electric and magnetic dipole moment. Here, we theoretically investigate the trapping and loading dynamics, as well as the heating and loss rates, and conclude that $10^4$-$10^6$ molecules are likely to be trapped. Our trap would open new possibilities in molecular spectroscopy, studies of cold chemical reactions, and precision measurement, amongst other fields of physics.

description: The modern colonial representation of the world which in metropolitan France has emphatically manifested itself under the famous title of a mission civilisatrice depended on a methodological nationalism as well as a political-epistemological ethno- and eurocentrism. It thus constituted an imperial western subject position of representation. Yet this central subject position of representation has eventually been challenged and decentered by the historical process of decolonization since the 1950s. Hence this article investigates how and to what extent decolonization affected, changed and rearticulated the subject of representation. To do this it will focus on historical textbook knowledge in France in the 1960s. History textbooks are especially relevant in this regard insofar as they can be described as national autobiographies as well as prominent and effective media of the above mentioned modern (colonial) representation of the world.

description: We determine the weight spectra of the Reed-Muller codes $RM(m-3,m)$ for $m\ge 6$ and $RM(m-4,m)$ for $m\ge 8$. The technique used is induction on $m$, using that the sum of two weights in $RM(r-1,m-1)$ is a weight in $RM(r,m)$, and using the characterization by Kasami and Tokura of the weights in $RM(r,m)$ that lie between its minimum distance $2^{m-r}$ and the double of this minimum distance. We also derive the weights of $RM(3,8),\,RM(4,9),$ by the same technique. We conclude with a conjecture on the weights of $RM(m-c,m)$, where $c$ is fixed and $m$ is large enough.

description: In den frühen 190er Jahren nutze die chinesische Führung den internationalen Sport für ihr außenpolitisches Ziel der Neupositionierung der Volksrepublik China auf globaler Ebene. Damit versuchte sie auch, die bisherige geopolitische Situation in Asien gemäß ihren Interessen zu revidieren. Der Kulminationspunkt dieser Anstrengungen waren die Ersten Spiele der Neuen Aufstrebenden Kräfte (GANEFO), die im November 1963 in Jakarta abgehalten wurden und als Sport-Großereignis in vielerlei Hinsicht den Olympischen Spielen ähnelten. Die Volksrepublik leistete einen fundamentalen Beitrag zur Entstehung der Spiele, sendete die größte Delegation und gewann die meisten Medaillen. Der Artikel untersucht das Interesse und die Beteiligung Chinas an den GANEFO im Rahmen der Stärkung der chinesisch-indonesischen Beziehungen und des Versuchs, China als sozialistische Führungsmacht der afrikanischen und asiatischen Länder zu stilisieren. Die GANEFO sollten dementsprechend dazu dienen, Ideale des Afro-Asianismus im Sinne des revolutionären Sozialismus Chinas weltweit zu propagieren.

description: Parity games are two-player infinite-duration games on graphs that play a crucial role in various fields of theoretical computer science. Finding efficient algorithms to solve these games in practice is widely acknowledged as a core problem in formal verification, as it leads to efficient solutions of the model-checking and satisfiability problems of expressive temporal logics, e.g., the modal muCalculus. Their solution can be reduced to the problem of identifying sets of positions of the game, called dominions, in each of which a player can force a win by remaining in the set forever. Recently, a novel technique to compute dominions, called priority promotion, has been proposed, which is based on the notions of quasi dominion, a relaxed form of dominion, and dominion space. The underlying framework is general enough to accommodate different instantiations of the solution procedure, whose correctness is ensured by the nature of the space itself. In this paper we propose a new such instantiation, called delayed promotion, that tries to reduce the possible exponential behaviours exhibited by the original method in the worst case. The resulting procedure not only often outperforms the original priority promotion approach, but so far no exponential worst case is known.

description: Optimizing the photovoltaic efficiency of dye-sensitized solar cells (DSSC) based on staggered gap heterojunctions requires a detailed understanding of sub-band gap transitions in the visible from the dye directly to the substrate's conduction band (CB) (type-II DSSCs). Here, we calculate the optical absorption spectra and spatial distribution of bright excitons in the visible region for a prototypical DSSC, catechol on rutile TiO$_2$(110), as a function of coverage and deprotonation of the OH anchoring groups. This is accomplished by solving the Bethe-Salpeter equation (BSE) based on hybrid range-separated exchange and correlation functional (HSE06) density functional theory (DFT) calculations. Such a treatment is necessary to accurately describe the interfacial level alignment and the weakly bound charge transfer transitions that are the dominant absorption mechanism in type-II DSSCs. Our HSE06 BSE spectra agree semi-quantitatively with spectra measured for catechol on anatase TiO$_2$ nanoparticles. Our results suggest deprotonation of catechol's OH anchoring groups, while being nearly isoenergetic at high coverages, shifts the onset of the absorption spectra to lower energies, with a concomitant increase in photovoltaic efficiency. Further, the most relevant bright excitons in the visible region are rather intense charge transfer transitions with the electron and hole spatially separated in both the [110] and [001] directions. Such detailed information on the absorption spectra and excitons is only accessible via periodic models of the combined dye-substrate interface.

description: We present the results for the Generalized Transverse Momentum Distribution related to quark Orbital Angular Momentum, {\it i.e.} $F_{14}$, in the MIT bag model. This model has been modified to include the Peierls--Yoccoz projection to restore translational invariance. Such a modification allows to fulfill more satisfactorily basic sum rules, that would otherwise be less elegantly carried out with the original version. Using the same model, we have calculated the twist-$3$ GPD that corresponds to Orbital Angular Momentum à la Ji, through the Penttinen--Polyakov--Shuvaev--Strikman sum rule. Recently, a new relation between the two definitions of the quark Orbital Angular Momentum at the density level has been proposed, which we illustrate here within the model. The sum rule is fulfilled. Still within the framework of the MIT bag model, we analyze the Wandzura--Wilczek expression for the GPD of interest. The genuine quark-gluon contribution is evaluated directly thanks to the equation of motion of the bag, which allows for a direct control of the kinematical contributions to the twist-3 GPD.

description: Nach dem Ende der japanischen Besatzung der Philippinen 1945 wurden dort Prozesse zur Verfolgung von Kriegsverbrechen und von Landesverrat initiiert. Während im ersten Fall eine universalistische Kategorie von Verbrechen zur Strafe stand, ging es im zweiten Fall meist um den Verrat an der Nation, die als Opfer definiert wurde. Im Januar 1948 erklärte Manuel Roxas eine Präsidialamnestie für alle des Landesverrats Beschuldigten mit Ausnahme von Kollaborateuren aus dem Militär und der Polizei, Spionen, Informanten und gewalttätiger Verbrechen Beschuldigter. Die meisten der Fälle von Landesverrat, die diese Amnestie nicht umfasste, betrafen Personen, die Formen von Gräuel begangen hatte, die in Prozessen gegen Japaner als Kriegsverbrechen eingestuft wurden. Dieser Artikel untersucht den Prozess der gerichtlichen Aufarbeitung von Gewaltverbrechen und sexueller Gewalt, meist begangen durch Kollaborateure aus dem Militär und der Polizei, in den Philippinen nach 1945 gemäß dem Gesetz gegen Verrat. Im Mittelpunkt steht die Frage, inwiefern – ungeachtet der Tatsache, dass die Kriegsverbrecherprozesse der frühen Nachkriegszeit den Erwartungen in vielerlei Form nicht entsprachen – die alternative Kategorisierung von Brutalität im Krieg als Landesverrat nicht auch hochproblematisch war.

description: Alan Pinkerton: Business and Intelligence in the American Civil War Based on the example of private detective Alan Pinkerton (1819–1884) the author analyses the mixture of activities of state and private intelligence services during the American Civil War. While this task was a traditional duty of the state in Europe, the United States had developed during the continental expansion a specific anti-etatistic tradition on the frontier. Against this background it is not surprising that Pinkerton succeeded to sell his services to an administration that had so far not been dealing with issues of intelligence on contract basis. Nagler furthermore shows how conflicts of interest as well as of loyalty caused Pinkerton to revoke his services, a fact which in turn led to an institutionalisation of the intelligence services in the United States.

description: Ein patriotischer Söldner? Sir Julius von Hartmann: ein Hannoveranischer Offizier im Britischen Dienst, 1803–1816 Die Autoren lenken den Blick auf überraschende Kontinuitäten von Fremdenlegionen in einer Ära, die gemeinhin mit dem Aufkommen der Nationalheere und der wehrpflichtigen Bürgersoldaten assoziiert wird – die Napoleonischen Kriege. Eine dieser Fremdenlegionen war die King‘s German Legion (KGL). Nachdem das Kurfürstentum Hannover 1803 durch französische Truppen besetzt worden war, emigrierten zahlreiche hannoversche Veteranen nach Großbritannien, um dort in den Militärdienst der KGL überzutreten. Am Werdegang des Artillerieoffiziers Julius von Hartmann (1774–1856) zeigen Heinzen und Wishon die damit verbundenen rechtlichen, sozio-kulturellen und politischen Zustände des betwixt-and-between auf, insbesondere die Stellung zwischen professionellem opportunistischem Söldnertum und Patriotismus. Dadurch konnte sich Hartmann nicht nur zum Vermittler professioneller Expertise entwickeln, sondern auch zum Repräsentanten einer transnationalen europäischen Militärkultur.

description: Diffuse star clusters (DSCs) are old and dynamically hot stellar systems that have lower surface brightness and more extended morphology than globular clusters (GCs). Using the images from HST/ACS Fornax Cluster Survey, we find that 12 out of 43 early-type galaxies (ETGs) in the Fornax cluster host significant numbers of DSCs. Together with literature data from the HST/ACS Virgo Cluster Survey, where 18 out of 100 ETGs were found to host DSCs, we systematically study the relationship of DSCs with GCs, and their host galaxy environment. Two DSC hosts are post-merger galaxies, with most of the other hosts either having low mass or showing clear disk components. We find that while the number ratio of DSCs to GCs is nearly constant in massive galaxies, the DSC-to-GC ratio becomes systematically higher in lower mass hosts. This suggests that DSCs may be more efficient at forming (or surviving) in low density environments. DSC hosts are not special either in their position in the cluster, or in the galactic color-magnitude diagram. Why some disk and low-mass galaxies host DSCs while others do not is still a puzzle, however. The mean ages of DSC hosts and non-hosts are similar at similar masses, implying that formation efficiency, rather than survival, is the reason behind different DSC number fractions in early-type galaxies.

description: We study the Li--Yau inequality for the heat equation corresponding to the Dunkl harmonic oscillator, which is a non-local Schrödinger operator parameterized by reflections and multiplicity functions. In the particular case when the reflection group is isomorphic to $\mathbb{Z}_2^d$, the result is sharp in the sense that equality is achieved by the heat kernel of the classic harmonic oscillator. We also provide the application on parabolic Harnack inequalities.

description: In the present work, a hyperelastic constitutive model based on neural networks is proposed which fulfills all common constitutive conditions by construction, and in particular, is applicable to compressible material behavior. Using different sets of invariants as inputs, a hyperelastic potential is formulated as a convex neural network, thus fulfilling symmetry of the stress tensor, objectivity, material symmetry, polyconvexity, and thermodynamic consistency. In addition, a physically sensible stress behavior of the model is ensured by using analytical growth terms, as well as normalization terms which ensure the undeformed state to be stress free and with zero energy. In particular, polyconvex, invariant-based stress normalization terms are formulated for both isotropic and transversely isotropic material behavior. By fulfilling all of these conditions in an exact way, the proposed physics-augmented model combines a sound mechanical basis with the extraordinary flexibility that neural networks offer. Thus, it harmonizes the theory of hyperelasticity developed in the last decades with the up-to-date techniques of machine learning. Furthermore, the non-negativity of the hyperelastic neural network-based potentials is numerically examined by sampling the space of admissible deformations states, which, to the best of the authors' knowledge, is the only possibility for the considered nonlinear compressible models. For the isotropic neural network model, the sampling space required for that is reduced by analytical considerations. In addition, a proof for the non-negativity of the compressible Neo-Hooke potential is presented. The applicability of the model is demonstrated by calibrating it on data generated with analytical potentials, which is followed by an application of the model to finite element simulations. In addition, an adaption of the model to noisy data is shown and its [...]

description: Topological fixpoint logics are a family of logics that admits topological models and where the fixpoint operators are defined with respect to the topological interpretations. Here we consider a topological fixpoint logic for relational structures based on Stone spaces, where the fixpoint operators are interpreted via clopen sets. We develop a game-theoretic semantics for this logic. First we introduce games characterising clopen fixpoints of monotone operators on Stone spaces. These fixpoint games allow us to characterise the semantics for our topological fixpoint logic using a two-player graph game. Adequacy of this game is the main result of our paper. Finally, we define bisimulations for the topological structures under consideration and use our game semantics to prove that the truth of a formula of our topological fixpoint logic is bisimulation-invariant.

Full-Wave Feasibility Study of Anti-Radar Diagnostic of Magnetic Field Based on O-X Mode Conversion and Oblique Reflectometry Imaging

description: An innovative millimeter wave diagnostic is proposed to measure the local magnetic field and edge current as a function of the minor radius in the tokamak pedestal region. The idea is to identify the direction of minimum reflectivity at the O-mode cutoff layer. Correspondingly, the transmissivity due to O-X mode conversion is maximum. That direction, and the angular map of reflectivity around it, contain information on the magnetic field vector B at the cutoff layer. Probing the plasma with different wave frequencies provides the radial profile of B. Full-wave finite-element simulations are presented here in 2D slab geometry. Modeling confirms the existence of a minimum in reflectivity that depends on the magnetic field at the cutoff, as expected from mode conversion physics, giving confidence in the feasibility of the diagnostic. The proposed reflectometric approach is expected to yield superior signal-to-noise ratio and to access wider ranges of density and magnetic field, compared with related radiometric techniques that require the plasma to emit Electron Bernstein Waves. Due to computational limitations, frequencies of 10-20 GHz were considered in this initial study. Frequencies above the edge electron-cyclotron frequency (f>28 GHz here) would be preferable for the experiment, because the upper hybrid resonance and right cutoff would lie in the plasma, and would help separate the O-mode of interest from spurious X-waves.

General Sub-packetized Access-Optimal Regenerating Codes

description: This paper presents a novel construction of $(n,k,d=n-1)$ access-optimal regenerating codes for an arbitrary sub-packetization level $α$ for exact repair of any systematic node. We refer to these codes as general sub-packetized because we provide an algorithm for constructing codes for any $α$ less than or equal to $r^{\lceil \frac{k}{r} \rceil}$ where $\frac{k}{r}$ is not necessarily an integer. This leads to a flexible construction of codes for different code rates compared to existing approaches. We derive the lower and the upper bound of the repair bandwidth. The repair bandwidth depends on the code parameters and $α$. The repair process of a failed systematic node is linear and highly parallelized, which means that a set of $\lceil \fracα{r} \rceil$ symbols is independently repaired first and used along with the accessed data from other nodes to recover the remaining symbols.

description: We present a scheme to enhance the atom number in magneto-optical traps of strontium atoms operating on the 461 nm transition. This scheme consists of resonantly driving the $^1$S$_0\to^3$P$_1$ intercombination line at 689 nm, which continuously populates a short-lived reservoir state and, as expected from a theoretical model, partially shields the atomic cloud from losses arising in the 461 nm cooling cycle. We show a factor of two enhancement in the atom number for the bosonic isotopes $^{88}$Sr and $^{84}$Sr, and the fermionic isotope $^{87}$Sr, in good agreement with our model. Our scheme can be applied in the majority of strontium experiments without increasing the experimental complexity of the apparatus, since the employed 689 nm transition is commonly used for further cooling. Our method should thus be beneficial to a broad range of quantum science and technology applications exploiting cold strontium atoms, and could be extended to other atomic species.

description: Quantitative description of charge transport across tunneling and break-junction devices with novel superconductors encounters some problems not present, or not as severe for traditional superconducting materials. In this work, we explain unexpected features in related transport characteristics as an effect of a degraded nano-scaled sheath at the superconductor surface. Model capturing main aspects of the ballistic charge transport across hybrid superconducting structures with normally-conducting nm-thick interlayers is proposed. The calculations are based on a scattering formalism taking into account Andreev electron-into-hole (and inverse) reflections at normal metal-superconductor interfaces as well as transmission and backscattering events in insulating barriers between the electrodes. Current-voltage characteristics of such devices exhibit a rich diversity of anomalous (from the viewpoint of the standard theory) features, in particular, shift of differential-conductance maximums at gap voltages to lower positions and appearance of well-defined dips instead expected coherence peaks. We compare our results with related experimental data.

Stochastic Equilibria under Imprecise Deviations in Terminal-Reward Concurrent Games

description: We study the existence of mixed-strategy equilibria in concurrent games played on graphs. While existence is guaranteed with safety objectives for each player, Nash equilibria need not exist when players are given arbitrary terminal-reward objectives, and their existence is undecidable with qualitative reachability objectives (and only three players). However, these results rely on the fact that the players can enforce infinite plays while trying to improve their payoffs. In this paper, we introduce a relaxed notion of equilibria, where deviations are imprecise. We prove that contrary to Nash equilibria, such (stationary) equilibria always exist, and we develop a PSPACE algorithm to compute one.

A black hole toy model with non-local and boundary modes from non-trivial boundary conditions

description: We study gauge theories between two parallel boundaries with non-trivial boundary conditions, which serve as a toy model for black hole background with two boundaries near the horizon and infinite, aiming for a better understanding of the Bekenstein-Hawking entropy. The new set of boundary conditions allows boundary modes and non-local modes that interplay between the two boundaries. Those boundary modes and Wilson lines stretched between the two boundaries are carefully analyzed and are confirmed as physical variables in the phase space. Along with bulk fluctuation modes and topological modes, the partition function and entropy of all physical modes are evaluated via Euclidean path integral. It is shown that there are transitions between the dominance of different modes as we vary the temperature. The boundary fluctuation modes whose entropy is proportional to the volume dominate at high temperatures, and the boundary-area scaled boundary modes and Wilson lines are the more important at low temperatures. At super-low temperatures, when all the fluctuation modes die off, we see the topological modes whose entropy is the logarithm of the length scales of the system. The boundary modes and non-local modes should have their counterparts in a black hole system with similar boundary conditions, which might provide important hints for black hole physics.
