Mapping current and activity fluctuations in exclusion processes: consequences and open questions
Matthieu Vanicat, Eric Bertin, Vivien Lecomte +1
Considering the large deviations of activity and current in the Asymmetric Simple Exclusion Process (ASEP), we show that there exists a non-trivial correspondence between the joint…
From bulk descriptions to emergent interfaces: connecting the Ginzburg-Landau and elastic line models
Nirvana Caballero, Elisabeth Agoritsas, Vivien Lecomte +1
Controlling interfaces is highly relevant from a technological point of view. However, their rich and complex behavior makes them very difficult to describe theoretically, and henc…
Hysteretic depinning of a particle in a periodic potential: Phase diagram and criticality
Víctor H. Purrello, José L. Iguain, Vivien Lecomte +1
We consider a massive particle driven with a constant force in a periodic potential and subjected to a dissipative friction. As a function of the drive and damping, the phase diagr…
Current statistics and depinning transition for a one-dimensional Langevin process in the weak-noise limit
Nicolás Tizón-Escamilla, Vivien Lecomte, Eric Bertin
We consider a particle with a Langevin dynamics driven by a uniform non-conservative force, in a one-dimensional potential with periodic boundary conditions. We are interested in t…
Nonlocal stationary probability distributions and escape rates for an active Ornstein-Uhlenbeck particle
Eric Woillez, Yariv Kafri, Vivien Lecomte
We evaluate the steady-state distribution and escape rate for an Active Ornstein-Uhlenbeck Particle (AOUP) using methods from the theory of large deviations. The calculation is car…
