Local Detailed Balance : A Microscopic Derivation

Michel Bauer, Françoise Cornu

Thermal contact is the archetype of non-equilibrium processes driven by constant non-equilibrium constraints when the latter are enforced by reservoirs exchanging conserved microsc…

Random matrices and entanglement entropy of trapped Fermi gases

Pasquale Calabrese, Pierre Le Doussal, Satya N. Majumdar

We exploit and clarify the use of random matrix theory for the calculation of the entanglement entropy of free Fermi gases. We apply this method to obtain analytic predictions for…

Convex hull of a Brownian motion in confinement

M. Chupeau, O. Bénichou, S. N. Majumdar

We study the effect of confinement on the mean perimeter of the convex hull of a planar Brownian motion, defined as the minimum convex polygon enclosing the trajectory. We use a mi…

Statistics of the longest interval in renewal processes

Claude Godreche, Satya N. Majumdar, Gregory Schehr

We consider renewal processes where events, which can for instance be the zero crossings of a stochastic process, occur at random epochs of time. The intervals of time between even…

Finite temperature free fermions and the Kardar-Parisi-Zhang equation at finite time

David S. Dean, Pierre Le Doussal, Satya N. Majumdar +1

We consider the system of one-dimensional free fermions confined by a harmonic well at finite inverse temperature . The average density of fermi…

Entropies of deformed binomial distributions

H. Bergeron, E. M. F. Curado, J. P. Gazeau +1

Asymptotic behavior (with respect to the number of trials) of symmetric generalizations of binomial distributions and their related entropies are studied through three examples. Th…

Fully developed isotropic turbulence: nonperturbative renormalization group formalism and fixed point solution

Léonie Canet, Bertrand Delamotte, Nicolás Wschebor

We investigate the regime of fully developed homogeneous and isotropic turbulence of the Navier-Stokes (NS) equation in the presence of a stochastic forcing, using the nonperturbat…

The contact theorem for charged fluids: from planar to curved geometries

Juan Pablo Mallarino, Gabriel Tellez, Emmanuel Trizac

When a Coulombic fluid is confined between two parallel charged plates, an exact relation links the difference of ionic densities at contact with the plates, to the surface charges…

Effect of Curvature and Confinement on the Casimir-Polder Interaction

Pablo Rodriguez-Lopez, Thorsten Emig, Ehsan Noruzifar +1

Modifications of Casimir-Polder interactions due to confinement inside a cylindrical cavity and due to curvature in- and outside the cavity are studied. We consider a perfectly con…

Ensemble inequivalence in a mean-field XY model with ferromagnetic and nematic couplings

Arkady Pikovsky, Shamik Gupta, Tarcisio N. Teles +4

We explore ensemble inequivalence in long-range interacting systems by studying an XY model of classical spins with ferromagnetic and nematic coupling. We demonstrate the inequival…

Scaling properties of field-induced superdiffusion in Continous Time Random Walks

R. Burioni, G. Gradenigo, A. Sarracino +2

We consider a broad class of Continuous Time Random Walks with large fluctuations effects in space and time distributions: a random walk with trapping, describing subdiffusion in d…

Statistics of the first passage time of Brownian motion conditioned by maximum value or area

Michael J. Kearney, Satya N. Majumdar

We derive the moments of the first passage time for Brownian motion conditioned by either the maximum value or the area swept out by the motion. These quantities are the natural co…

First order transition for the optimal search time of Lévy flights with resetting

Lukasz Kusmierz, Satya N. Majumdar, Sanjib Sabhapandit +1

We study analytically an intermittent search process in one dimension. There is an immobile target at the origin and a searcher undergoes a discrete time jump process starting at $…

Anomalous transport of impurities in inelastic Maxwell gases

Vicente Garzó, Nagi Khalil, Emmanuel Trizac

A mixture of dissipative hard grains generically exhibits a breakdown of kinetic energy equipartition. The undriven and thus freely cooling binary problem, in the tracer limit wher…

Non-local response in a lattice gas under a shear drive

Tridib Sadhu, Satya N. Majumdar, David Mukamel

In equilibrium, the effect of a spatially localised perturbation is typically confined around the perturbed region. Quite contrary to this, in a non-equilibrium stationary state of…

Columnar order and Ashkin-Teller criticality in mixtures of hard-squares and dimers

Kabir Ramola, Kedar Damle, Deepak Dhar

We show that critical exponents of the transition to columnar order in a {\em mixture} of dimers and hard-squares on the square lattice {\em depends on th…

Memory effect in uniformly heated granular gases

E. Trizac, A. Prados

We evidence a Kovacs-like memory effect in a uniformly driven granular gas. A system of inelastic hard particles, in the low density limit, can reach a non-equilibrium steady state…

A parity breaking Ising chain Hamiltonian as a Brownian motor

F. Cornu, H. J. Hilhorst

We consider the translationally invariant but parity (left-right symmetry) breaking Ising chain Hamiltonian \begin{equation} {\cal H} = -U_2\sum_{k} s_{k}s_{k+1} - U_3\sum_{k} s_{k…

Clustering of branching Brownian motions in confined geometries

Andrea Zoia, Eric Dumonteil, Alain Mazzolo +2

We study the evolution of a collection of individuals subject to Brownian diffusion, reproduction and disappearance. In particular, we focus on the case where the individuals are i…
