Statistics of zero crossings in rough interfaces with fractional elasticity
Arturo L. Zamorategui, Vivien Lecomte, Alejandro B. Kolton
We study numerically the distribution of zero crossings in one-dimensional elastic interfaces described by an overdamped Langevin dynamics with periodic boundary conditions. We mod…
Dynamical phase transitions in the current distribution of driven diffusive channels
Yongjoo Baek, Yariv Kafri, Vivien Lecomte
We study singularities in the large deviation function of the time-averaged current of diffusive systems connected to two reservoirs. A set of conditions for the occurrence of phas…
Rules of calculus in the path integral representation of white noise Langevin equations: the Onsager-Machlup approach
Leticia F. Cugliandolo, Vivien Lecomte
The definition and manipulation of Langevin equations with multiplicative white noise require special care (one has to specify the time discretisation and a stochastic chain rule h…
