Infinite systems of interacting chains with memory of variable length - a stochastic model for biological neural nets
Antonio Galves, Eva Löcherbach
We consider a new class of non Markovian processes with a countable number of interacting components. At each time unit, each component can take two values, indicating if it has a…
Gelfand-Shilov smoothing properties of the radially symmetric spatially homogeneous Boltzmann equation without angular cutoff
Nicolas Lerner, Yoshinori Morimoto, Karel Pravda-Starov +1
We prove that the Cauchy problem associated to the radially symmetric spatially homogeneous non-cutoff Boltzmann equation with Maxwellian molecules enjoys the same Gelfand-Shilov r…
Conductivity of graphene with resonant and non-resonant adsorbates
Guy Trambly De Laissardière, Didier Mayou
We propose a unified description of transport in graphene with adsorbates that fully takes into account localization effects and loss of electronic coherence due to inelastic proce…
Tannaka-Krein duality for compact quantum homogeneous spaces. II. Classification of quantum homogeneous spaces for quantum SU(2)
Kenny De Commer, Makoto Yamashita
We apply the Tannaka-Krein duality theory for quantum homogeneous spaces, developed in the first part of this series of papers, to the case of the quantum SU(2) groups. We obtain a…
Electric-field control of the magnetic anisotropy in an ultrathin (Ga,Mn)As/(Ga,Mn)(As,P) bilayer
Tarik Niazi, Mathieu Cormier, Damien Lucot +4
We report on the electric control of the magnetic anisotropy in an ultrathin ferromagnetic (Ga,Mn)As/(Ga,Mn)(As,P) bilayer with competing in-plane and out-of-plane anisotropies. Th…
Almost Hadamard matrices: the case of arbitrary exponents
Teodor Banica, Ion Nechita
In our previous work, we introduced the following relaxation of the Hadamard property: a square matrix is called "almost Hadamard" if is orthog…
High SiO abundance in the HH212 protostellar jet
Sylvie Cabrit, Claudio Codella, Frédéric Gueth +1
Previous SiO maps of the innermost regions of HH212 set strong constraints on the structure and origin of this jet. They rule out a fast wide-angle wind, and tentatively favor a ma…
Bogoliubov spectrum of interacting Bose gases
Mathieu Lewin, Phan Thành Nam, Sylvia Serfaty +1
We study the large-N limit of a system of N bosons interacting with a potential of intensity 1/N. When the ground state energy is to the first order given by Hartree's theory, we s…
Surface critical behaviour of the vertex-interacting self-avoiding walk on the square lattice
Damien P. Foster, Claire Pinettes
The phase diagram and surface critical behaviour of the vertex-interacting self-avoiding walk are examined using transfer matrix methods extended using DMRG and coupled with finite…
Scale-free unique continuation estimates and applications to random Schrödinger operators
Constanza Rojas-Molina, Ivan Veselic
We prove a unique continuation principle or uncertainty relation valid for Schrödinger operator eigenfunctions, or more generally solutions of a Schrödinger inequality, on cubes of…
Melting of Rare-Gas Crystals: Monte Carlo Simulation versus Experiments
Virgile Bocchetti, Hung T. Diep
We study the melting transition in crystals of rare gas Ar, Xe, and Kr by the use of extensive Monte Carlo simulations with the Lennard-Jones potential. The parameters of this pote…
Semantically Secure Lattice Codes for the Gaussian Wiretap Channel
Cong Ling, Laura Luzzi, Jean-Claude Belfiore +1
We propose a new scheme of wiretap lattice coding that achieves semantic security and strong secrecy over the Gaussian wiretap channel. The key tool in our security proof is the fl…
Symmetry-protected topological phases of alkaline-earth cold fermionic atoms in one dimension
H. Nonne, M. Moliner, S. Capponi +2
We investigate the existence of symmetry-protected topological phases in one-dimensional alkaline-earth cold fermionic atoms with general half-integer nuclear spin I at half fillin…
Unravelling the intrinsic and robust nature of van Hove singularities in twisted bilayer graphene
I. Brihuega, P. Mallet, H. González-Herrero +6
Extensive scanning tunnelling microscopy and spectroscopy experiments complemented by first principles and parameterized tight binding calculations provide a clear answer to the ex…
Monitoring procedure for parameter change in causal time series
Jean-Marc Bardet, William Chakry Kengne
We propose a new sequential procedure to detect change in the parameters of a process belonging to a large class of causal models (such as AR(), ARCH(…
A lower bound on the blow-up rate for the Davey-Stewartson system on the torus
Nicolas Godet
We consider the hyperbolic-elliptic version of the Davey-Stewartson system with cubic nonlinearity posed on the two dimensional torus. A natural setting for studying blow up soluti…
Re-orientation Transition in Molecular Thin Films: Potts Model with Dipolar Interaction
Danh-Tai Hoang, Maciej Kasperski, Henryk Puszkarski +1
We study the low-temperature behavior and the phase transition of a thin film by Monte Carlo simulation. The thin film has a simple cubic lattice structure where each site is occup…
Dynamical Ionization Bounds for Atoms
Enno Lenzmann, Mathieu Lewin
We study the long-time behavior of the 3-dimensional repulsive nonlinear Hartree equation with an external attractive Coulomb potential , which is a nonlinear model for the…
Finite Alphabet Iterative Decoders, Part II: Improved Guaranteed Error Correction of LDPC Codes via Iterative Decoder Diversity
David Declercq, Bane Vasic, Shiva Kumar Planjery +1
Recently, we introduced a new class of finite alphabet iterative decoders (FAIDs) for low-density parity-check (LDPC) codes. These decoders are capable of surpassing belief propaga…
Consequences of the choice of a particular basis of for the cubic wave equation on the sphere and the Euclidian space
Anne-Sophie de Suzzoni
In this paper, the almost sure global well-posedness of the cubic non linear wave equation on the sphere is studied when the initial datum is a random variable with values in low r…
A Numerical Perspective on Hartree-Fock-Bogoliubov Theory
Mathieu Lewin, Séverine Paul
The method of choice for describing attractive quantum systems is Hartree-Fock-Bogoliubov (HFB) theory. This is a nonlinear model which allows for the description of pairing effect…

Susanna Terracini, Nikolay Tzvetkov, Nicola Visciglia
We study the nature of the Nonlinear Schrödinger equation ground states on the product spaces , where is a compact Riemannian manifold. We prove that for smal…
Construction of the Pauli-Villars-regulated Dirac vacuum in electromagnetic fields
Philippe Gravejat, Christian Hainzl, Mathieu Lewin +1
Using the Pauli-Villars regularization and arguments from convex analysis, we construct solutions to the classical time-independent Maxwell equations in Dirac's vacuum, in the pres…
