Hydrodynamic equations for self-propelled particles: microscopic derivation and stability analysis
Eric Bertin, Michel Droz, Guillaume Grégoire
Considering a gas of self-propelled particles with binary interactions, we derive the hydrodynamic equations governing the density and velocity fields from the microscopic dynamics…
Maximum relative height of one-dimensional interfaces : from Rayleigh to Airy distribution
Joachim Rambeau, Gregory Schehr
We introduce an alternative definition of the relative height h^κ(x) of a one-dimensional fluctuating interface indexed by a continuously varying real paramater 0 \leq κ\leq 1. It…
Charge and Current Sum Rules in Quantum Media Coupled to Radiation
Ladislav Samaj
This paper concerns the equilibrium bulk charge and current density correlation functions in quantum media, conductors and dielectrics, fully coupled to the radiation (the retarded…
Equilibrium long-ranged charge correlations at the interface between media coupled to the electromagnetic radiation
Bernard Jancovici, Ladislav Samaj
We continue studying long-ranged quantum correlations of surface charge densities on the interface between two media of distinct dielectric functions which are in thermal equilibri…
Ground state energy of the two-dimensional weakly interacting Bose gas: First correction beyond Bogoliubov theory
Christophe Mora, Yvan Castin
We consider the grand potential of a two-dimensional weakly interacting homogeneous Bose gas at zero temperature. Building on a number-conserving Bogoliubov method for a lattic…
