Masur-Veech volumes and intersection theory: the principal strata of quadratic differentials
D. Chen, M. Möller, A. Sauvaget +3
We describe a conjectural formula via intersection numbers for the Masur-Veech volumes of strata of quadratic differentials with prescribed zero orders, and we prove the formula fo…
Dynamics of the Price Behavior in Stock Market: A Statistical Physics Approach
Hung T. Diep, Gabriel Desgranges
We study in this paper the time evolution of stock markets using a statistical physics approach. Each agent is represented by a spin having a number of discrete states or conti…
Exterior energy bounds for the critical wave equation close to the ground state
Thomas Duyckaerts, Carlos E. Kenig, Frank Merle
By definition, the exterior asymptotic energy of a solution to a wave equation on is the sum of the limits as of the energy in the the exterior…
Time optimal observability for Grushin Schrödinger equation
Nicolas Burq, Chenmin Sun
We consider two dimensional Grushin Schrödinger equation posed on a finite cylinder $Ω=(-1,1)_x\times \T_y$ with Dirichlet boundary condition. We obtain the sharp observability by…
Entanglement front generated by an impurity travelling in an isolated many-body quantum system
Andrea De Luca, Alvise Bastianello
We investigate the effect on the entanglement dynamics of an impurity moving at constant velocity in a closed quantum system. We focus on one-dimensional strongly-correlated lattic…
Enacting planets to learn physics
Emmanuel Rollinde, N Decamp
The Solar System motivates students to interest themselves in sciences, as a large number of concepts may be easily introduced through the observation and understanding of planet's…
Universal behaviors in the wrinkling transition of disordered membranes
O. Coquand, K. Essafi, J. -P. Kownacki +1
The wrinkling transition experimentally identified by Mutz et al. [Phys. Rev. Lett. 67, 923 (1991)] and then thoroughly studied by Chaieb et al. [Phys. Rev. Lett. 96, 078101 (2006)…
Nonlocal interferences induced by the phase of the wavefunction for a particle in a cavity with moving boundaries
Mordecai Waegell, Alex Matzkin
We investigate the dynamics of a particle in a confined periodic system---a time-dependent oscillator confined by infinitely high and moving walls---and focus on the evolution of t…
Cross frequency coupling in next generation inhibitory neural mass models
Andrea Ceni, Simona Olmi, Alessandro Torcini +1
Coupling among neural rhythms is one of the most important mechanisms at the basis of cognitive processes in the brain. In this study we consider a neural mass model, rigorously ob…
Effects of Radiation in Accretion Regions of Classical T Tauri Stars: Pre-heating of accretion column in non-LTE regime
Salvatore Colombo, Laurent Ibgui, Salvatore Orlando +8
Models and observations indicate that the impact of matter accreting onto the surface of young stars produces regions at the base of accretion columns, in which optically thin and…
Quantum localization and electronic transport in covalently functionalized carbon nanotubes
Ghassen Jemaï, Jouda Khabthani, Guy Trambly de Laissardière +1
Carbon nanotubes are of central importance for applications in nano-electronics thanks to their exceptional transport properties. They can be used as sensors, for example in biolog…
Universal behavior in non stationary Mean Field Games
Thibault Bonnemain, Thierry Gobron, Denis Ullmo
Mean Field Games provide a powerful framework to analyze the dynamics of a large number of controlled objects in interaction. Though these models are much simpler than the underlyi…
Non-LTE radiation hydrodynamics in PLUTO
Salvatore Colombo, Laurent Ibgui, Salvatore Orlando +5
Modeling the dynamics of most astrophysical structures requires an adequate description of the radiation-matter interaction. Several numerical (magneto)hydrodynamics codes were upg…
Thermodynamic properties of the Shastry-Sutherland model throughout the dimer-product phase
Alexander Wietek, Philippe Corboz, Stefan Wessel +3
The thermodynamic properties of the Shastry-Sutherland model have posed one of the longest-lasting conundrums in frustrated quantum magnetism. Over a wide range on both sides of th…
Coexistence of fast and slow gamma oscillations in one population of inhibitory spiking neurons
Hongjie Bi, Marco Segneri, Matteo di Volo +1
Oscillations are a hallmark of neural population activity in various brain regions with a spectrum covering a wide range of frequencies. Within this spectrum gamma oscillations hav…
Horizontal gene transfer: numerical comparison between stochastic and deterministic approaches
Vincent Calvez, Susely Figueroa Iglesias, Hélène Hivert +3
Horizontal gene Transfer (HT) denotes the transmission of genetic material between two living organisms, while the vertical transmission refers to a DNA transfer from parents to th…
Integral formulas and antisymmetrization relations for the six-vertex model
Luigi Cantini, Filippo Colomo, Andrei G. Pronko
We study the relationship between various integral formulas for nonlocal correlation functions of the six-vertex model with domain wall boundary conditions. Specifically, we show h…
Spectral statistics and many-body quantum chaos with conserved charge
Aaron J. Friedman, Amos Chan, Andrea De Luca +1
We investigate spectral statistics in spatially extended, chaotic many-body quantum systems with a conserved charge. We compute the spectral form factor analytically for a m…
On the divergence of Birkhoff Normal Forms
Raphaël Krikorian
It is well known that a real analytic symplectic diffeomorphism of the -dimensional disk () admitting the origin as a non-resonant elliptic fixed can be {\it formally}…
Multistability of Driven-Dissipative Quantum Spins
Haggai Landa, Marco Schiró, Grégoire Misguich
We study the dynamics of lattice models of quantum spins one-half, driven by a coherent drive and subject to dissipation. Generically the meanfield limit of these models manifests…
Domain wall problem in the quantum XXZ chain and semiclassical behavior close to the isotropic point
Grégoire Misguich, Nicolas Pavloff, Vincent Pasquier
We study the dynamics of a spin-1/2 XXZ chain which is initially prepared in a domain-wall state. We compare the results of time-dependent Density Matrix Renormalization Group simu…
1-dimensional Schrodinger operators with complex potentials
Jan Dereziński, Vladimir Georgescu
We discuss 1-dimensional Schrodinger operators with complex and locally integrable potentials that may have an arbitrary behavior at (finite or infinite) endpoints. The main tool o…
Ballistic transport and boundary resistances in inhomogeneous quantum spin chains
Alberto Biella, Mario Collura, Davide Rossini +2
Transport phenomena are central to physics, and transport in the many-body and fully-quantum regime is attracting an increasing amount of attention. It has been recently revealed t…
Separability and Symmetry Operators for Painlevé Metrics and their Conformal Deformations
