description: Let $(M,g)$ be a connected, closed, orientable Riemannian surface and denote by $λ_k(M,g)$ the $k$-th eigenvalue of the Laplace-Beltrami operator on $(M,g)$. In this paper, we consider the mapping $(M, g)\mapsto λ_k(M,g)$. We propose a computational method for finding the conformal spectrum $Λ^c_k(M,[g_0])$, which is defined by the eigenvalue optimization problem of maximizing $λ_k(M,g)$ for $k$ fixed as $g$ varies within a conformal class $[g_0]$ of fixed volume $textrm{vol}(M,g) = 1$. We also propose a computational method for the problem where $M$ is additionally allowed to vary over surfaces with fixed genus, $γ$. This is known as the topological spectrum for genus $γ$ and denoted by $Λ^t_k(γ)$. Our computations support a conjecture of N. Nadirashvili (2002) that $Λ^t_k(0) = 8 πk$, attained by a sequence of surfaces degenerating to a union of $k$ identical round spheres. Furthermore, based on our computations, we conjecture that $Λ^t_k(1) = \frac{8π^2}{\sqrt{3}} + 8π(k-1)$, attained by a sequence of surfaces degenerating into a union of an equilateral flat torus and $k-1$ identical round spheres. The values are compared to several surfaces where the Laplace-Beltrami eigenvalues are well-known, including spheres, flat tori, and embedded tori. In particular, we show that among flat tori of volume one, the $k$-th Laplace-Beltrami eigenvalue has a local maximum with value $λ_k = 4π^2 \left\lceil \frac{k}{2} \right\rceil^2 \left( \left\lceil \frac{k}{2} \right\rceil^2 - \frac{1}{4}\right)^{-\frac{1}{2}}$. Several properties are also studied computationally, including uniqueness, symmetry, and eigenvalue multiplicity.

description: We consider the volume-normalized Ricci flow close to compact shrinking Ricci solitons. We show that if a compact Ricci soliton $(M,g)$ is a local maximum of Perelman's shrinker entropy, any normalized Ricci flow starting close to it exists for all time and converges towards a Ricci soliton. If $g$ is not a local maximum of the shrinker entropy, we show that there exists a nontrivial normalized Ricci flow emerging from it. These theorems are analogues of results in the Ricci-flat and in the Einstein case.

description: Nature provides a vast new vista of opportunities for the preparation of new recyclable solvents. Natural compounds have been recently used to prepare the cationic or anionic moiety of room temperature ionic liquids. In many cases, these new solvents based on modification of natural products contain chiral centres and/or specific functional groups. This paper is an overview in an area of research that is destined to a rapid development and expansion.

description: We unconditionally prove a central limit theorem for linear statistics of the zeros of the Riemann zeta function with diverging variance. Previously, theorems of this sort have been proved under the assumption of the Riemann hypothesis. The result mirrors central limit theorems in random matrix theory that have been proved by Szegő, Spohn, and Soshnikov among others, and therefore provides support for the view that the zeros of the zeta function are distributed like the eigenvalues of a random matrix. A key ingredient in our proof is a simple bootstrapping of classical zero density estimates of Selberg and Jutila for the zeta function, which may be of independent interest.

description: Policy brief prepared by the COURAGE H2020 project.

The heritage and memory of opposition has gained particular urgency in view of neo-authoritarian tendencies in Eastern and South-Eastern Europe. The values of pluralism, democracy, and open societies are not unquestioned anymore. During the period of state socialism, individuals and groups challenged one-party communist dictatorships. Many committed themselves to democratic and liberal values and insisted on human rights, civic freedom, and the autonomy of the individual. Opposition to oppression was often articulated through culture and the arts; cultural opposition challenged the communists’ claim to a monopoly on knowledge, values, and norms.

The heritage of cultural opposition against state socialism is today an important resource for social reflection and innovation in Europe. However, as COURAGE has shown, this resource needs to be better acknowledged, and its significant symbolic power should be better exploited. Study and ongoing discussion and debate of the heritage of cultural opposition will counter one-sided interpretations of state socialism and the exclusion of important groups and individuals from history. It offers valuable knowledge about the practices of freedom and strategies against authoritarian governments. Cultural opposition under state socialism was incredibly creative. A nuanced grasp of these examples of cultural creativity under adverse conditions can help stimulate innovative acts and initiatives today.

description: We present a long-term phase-coherent timing analysis and pulse-phase resolved spectroscopy for the two outbursts observed from the transient anomalous X-ray pulsar CXOU J164710.2-45521. For the first outburst we used 11 Chandra and XMM-Newton observations between September 2006 to August 2009, the longest baseline yet for this source. We obtain a coherent timing solution with $P=10.61065583(4)$ s, $\dot{P} = 9.72(1) \times 10^{-13}\;$s s$^{-1}$ and $\ddot{P} = -1.05(5)\times10^{-20}\; $s s$^{-2}$. Under the standard assumptions this implies a surface dipolar magnetic field of $\sim 10^{14}$ G, confirming this source as a standard-$B$ magnetar. We also study the evolution of the pulse profile (shape, intensity and pulsed fraction) as a function of time and energy. Using the phase-coherent timing solution we perform a phase-resolved spectroscopy analysis, following the spectral evolution of pulse-phase features, which hints at the physical processes taking place on the star. The results are discussed from the perspective of magneto-thermal evolution models and the untwisting magnetosphere model. Finally, we present similar analysis for the second, less intense, 2011 outburst. For the timing analysis we used Swift data together with 2 XMM-Newton and Chandra pointings. The results inferred for both outbursts are compared and briefly discussed in a more general framework.

Duality in Gauge Field Theories
Supersymmetric Gauge Theory
Supersymmetry and Duality

description: Abstract: It is an interesting question whether a given infra-red duality between quantum field theories can be explained in terms of other more elementary dualities. For example recently it has been shown that mirror dualities can be obtained by iterative applications of Seiberg-like dualities. In this paper we continue this line of investigation focusing on theories with tensor matter. In such cases one can apply the idea of deconfinement, which consists of trading the tensor matter for extra gauge nodes by means of a suitable elementary duality. This gives an auxiliary dual frame which can then be manipulated with further dualizations, in an iterative procedure eventually yielding an interesting dual description of the original theory. The sequential deconfinement technique has avatars in different areas of mathematical physics, such as the study of hypergeometric and elliptic hypergeometric integral identities or of 2d free field correlators. We discuss various examples in the context 4dN = 1 supersymmetric theories, which are related to elliptic hypergeometric integrals. These include a new self-duality involving a quiver theory which exhibits a non-trivial global symmetry enhancement to E6.

Stable auto-equivalences for local symmetric algebras

Publisher: name: arXiv
Year: 2014
Subjects: subject: Representation Theory (math.RT)
subject: FOS: Mathematics

description: We construct nontrivial auto-equivalences of stable module categories for elementary, local symmetric algebras over a field k. These auto-equivalences are modeled after the spherical twists of Seidel and Thomas and the $\mathbb{P}^n$-twists of Huybrechts and Thomas, which yield auto-equivalences of the derived category of coherent sheaves on a variety. For group algebras of p-groups in characteristic p we recover many of the auto-equivalences corresponding to endo-trivial modules. We also obtain analogous auto-equivalences for local algebras of dihedral and semi-dihedral type, which are not group algebras.

Quantum Model for a Periodically Driven Selectivity Filter in K$^{+}$ Ion Channel

description: In this work, we present a quantum transport model for the selectivity filter in the KcsA potassium ion channel. This model is fully consistent with the fact that two conduction pathways are involved in the translocation of ions thorough the filter, and we show that the presence of a second path may actually bring advantages for the filter as a result of quantum interference. To highlight interferences and resonances in the model, we consider the selectivity filter to be driven by a controlled time-dependent external field which changes the free energy scenario and consequently the conduction of the ions. In particular, we demonstrate that the two-pathway conduction mechanism is more advantageous for the filter when dephasing in the transient configurations is lower than in the main configurations. As a matter of fact, K$^+$ ions in the main configurations are highly coordinated by oxygen atoms of the filter backbone and this increases noise. Moreover, we also show that, for a wide range of dephasing rates and driving frequencies, the two-pathway conduction used by the filter leads indeed to higher ionic currents when compared with the single path model.

description: Quel regard est véhiculé au travers de l’enseignement du fait colonial dans les manuels scolaires du Secondaire I dans le Canton de Vaud et en France ? En quoi l’arrivée du Plan d’études romand (PER) et des nouveaux Moyens d’enseignement romands (MER) apportent-ils un regard différent sur l’enseignement du fait colonial ? Autant de questions qui se posent au regard de la composition multiculturelle des sociétés vaudoise et française et du caractère socialement vif de la question du fait colonial. A partir de l’étude comparative entre les programmes scolaires français et vaudois et leurs manuels associés, ce travail propose de mettre en lumière le spectre sous lequel l’enseignement du fait colonial est abordé dans ces deux États voisins. Européocentrisme, francocentrisme, cette étude pointe les écueils des manuels d’Histoire actuellement utilisés en classe, malgré une timide incursion d’une volonté d’introduire vision plus universelle et objective du fait colonial. L’arrivée prochaine de nouveaux Moyens d’enseignement romands (MER) confirme et augmente considérablement la part belle qui est faite à l’étude des sociétés coloniales et au rapport à l’altérité, en utilisant un corpus documentaire renouvelé issu de situations coloniales diverses. Ces nouveaux moyens d’enseignement romands (MER) donneront le champ libre à l’enseignant pour aborder le fait colonial, notamment en ce qui concerne le rôle que la Suisse a pu jouer durant cette période. Cette analyse comparative a également permis de mettre en exergue le besoin de réformer en amont l’approche que les programmes français et romand ont des civilisations précoloniales d’Afrique et de l’Asie-Pacifique qui restent absentes des programmes scolaires actuels.

description: In this paper, the Turing instability in reaction-diffusion models defined on complex networks is studied. Here, we focus on three types of models which generate complex networks, i.e. the Erdős-Rényi, the Watts-Strogatz, and the threshold network models. From analysis of the Laplacian matrices of graphs generated by these models, we numerically reveal that stable and unstable regions of a homogeneous steady state on the parameter space of two diffusion coefficients completely differ, depending on the network architecture. In addition, we theoretically discuss the stable and unstable regions in the cases of regular enhanced ring lattices which include regular circles, and networks generated by the threshold network model when the number of vertices is large enough.

description: We study the spectral characteristics of spin current nano-oscillators based on the Pt/[Co/Ni] magnetic multilayer with perpendicular magnetic anisotropy. By varying the applied magnetic field and current, both localized and propagating spin wave modes of the oscillation are achieved. At small fields, we observe an abrupt onset of the modulation sidebands. We use micromagnetic simulations to identify this state as a dynamical magnetic skyrmion stabilized in the active device region by spin current injection, whose current-induced dynamics is accompanied by the gyrotropic motion of the core due to the skew deflection. Our results demonstrate a practical route for controllable skyrmion manipulation by spin current in magnetic thin films.

description: More than half a century after first being proposed by Sir Nevill Mott, the deceptively simple question of whether the interaction-driven electronic metal-insulator transition may be continuous remains enigmatic. Recent experiments on two-dimensional materials suggest that when the insulator is a quantum spin liquid, lack of magnetic long-range order on the insulating side may cause the transition to be continuous, or only very weakly first order. Motivated by this, we study a half-filled extended Hubbard model on a triangular lattice strip geometry. We argue, through use of large-scale numerical simulations and analytical bosonization, that this model harbors a continuous (Kosterlitz-Thouless-like) quantum phase transition between a metal and a gapless spin liquid characterized by a spinon Fermi surface, i.e., a "spinon metal." These results may provide a rare insight into the development of Mott criticality in strongly interacting two-dimensional materials and represent one of the first numerical demonstrations of a Mott insulating quantum spin liquid phase in a genuinely electronic microscopic model.

description: Motivated by experimental evidence for a mixed-valence state to occur in the neutralization of strontium ions on gold surfaces we analyze this type of charge-transferring atom-surface collision from a many-body theoretical point of view using quantum-kinetic equations together with a pseudo-particle representation for the electronic configurations of the atomic projectile. Particular attention is paid to the temperature dependence of the neutralization probability which--experimentally--seems to signal mixed-valence-type correlations affecting the charge-transfer between the gold surface and the strontium projectile. We also investigate the neutralization of magnesium ions on a gold surface which shows no evidence for a mixed-valence state. Whereas for magnesium excellent agreement between theory and experiment could be obtained, for strontium we could not reproduce the experimental data. Our results indicate mixed-valence correlations to be in principle present, but for the model mimicking most closely the experimental situation they are not strong enough to affect the neutralization process quantitatively.

description: The state sum models in two dimensions introduced by Fukuma, Hosono and Kawai are generalised by allowing algebraic data from a non-symmetric Frobenius algebra. Without any further data, this leads to a state sum model on the sphere. When the data is augmented with a crossing map, the partition function is defined for any oriented surface with a spin structure. An algebraic condition that is necessary for the state sum model to be sensitive to spin structure is determined. Some examples of state sum models that distinguish topologically-inequivalent spin structures are calculated.

description: In particulate soft matter systems the average number of contacts $Z$ of a particle is an important predictor of the mechanical properties of the system. Using X-ray tomography, we analyze packings of frictional, oblate ellipsoids of various aspect ratios $α$, prepared at different global volume fractions $ϕ_g$. We find that $Z$ is a monotonously increasing function of $ϕ_g$ for all $α$. We demonstrate that this functional dependence can be explained by a local analysis where each particle is described by its local volume fraction $ϕ_l$ computed from a Voronoi tessellation. $Z$ can be expressed as an integral over all values of $ϕ_l$: $Z(ϕ_g, α, X) = \int Z_l (ϕ_l, α, X) \; P(ϕ_l | ϕ_g) \; dϕ_l$. The local contact number function $ Z_l (ϕ_l, α, X)$ describes the relevant physics in term of locally defined variables only, including possible higher order terms $X$. The conditional probability $P(ϕ_l | ϕ_g)$ to find a specific value of $ϕ_l$ given a global packing fraction $ϕ_g$ is found to be independent of $α$ and $X$. Our results demonstrate that for frictional particles a local approach is not only a theoretical requirement but also feasible.

Orbits of rotor-router operation and stationary distribution of random walks on directed graphs

description: The rotor-router model is a popular deterministic analogue of random walk. In this paper we prove that all orbits of the rotor-router operation have the same size on a strongly connected directed graph (digraph) and give a formula for the size. By using this formula we address the following open question about orbits of the rotor-router operation: Is there an infinite family of non-Eulerian strongly connected digraphs such that the rotor-router operation on each digraph has a single orbit? It turns out that on a strongly connected digraph the stationary distribution of the simple random walk coincides with the frequency of vertices in a rotor walk. In this common aspect a rotor walk simulates a random walk. This gives one similarity between two models on (finite) digraphs.

Protocol for Counterfactually Transporting an Unknown Qubit
Creators: name: Salih, Hatim
Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum teleportation circumvents the uncertainty principle using dual channels: a quantum one consisting of previously-shared entanglement, and a classical one, together allowing the disembodied transport of an unknown quantum state over distance. It has recently been shown that a classical bit can be counterfactually communicated between two parties in empty space, "Alice" and "Bob". Here, by using our "dual" version of the chained quantum Zeno effect to achieve a counterfactual CNOT gate, we propose the first protocol for transporting an unknown qubit counterfactually, that is without any physical particles travelling between Alice and Bob - no classical channel and no previously-shared entanglement.

description: Dans ce travail, l’utilisation de Média, Images et Technologies de l’Information et de la Communication dans l’Enseignement (MITIC) dans l'enseignement des sciences de la nature (physique, chimie et biologie) au secondaire 1, particulièrement pour des classes de voie générale. Partant du constat que l’abstraction des phénomènes rencontrés en sciences, due à l'échelle où ils s’y produisent, ainsi que leur modélisation constitue un obstacle majeur et fréquent rencontré par les apprenants. Pour contourner cet obstacle, l’utilisation de trois outils basés sur de la réalité augmentée, des animations ou des vidéos pédagogiques a été mise oeuvre dans le cadre de séquences d’enseignement en cherchant à analyser les apports et les inconvénients aussi bien d’un point de vue pratique qu’à travers les ressentis de l’enseignant ou des élèves. Ces séquences d’apprentissage ont permis de montrer que l’utilisation de ces outils MITIC est assez facilement appréhendée par les apprenants mais est également bénéfique grâce à son apport cognitif et à la motivation qu’elle suscite. Tout ceci permet de favoriser l’acquisition de concepts importants dans le cadre de l’enseignement des sciences de la nature au secondaire 1.
