Fluctuating interfaces subject to stochastic resetting
Shamik Gupta, Satya N. Majumdar, Gregory Schehr
We study one-dimensional fluctuating interfaces of length where the interface stochastically resets to a fixed initial profile at a constant rate . For finite in the lim…
Index Distribution of Cauchy Random Matrices
Ricardo Marino, Satya N. Majumdar, Grégory Schehr +1
Using a Coulomb gas technique, we compute analytically the probability that a large Cauchy random matrix has positive eigenvalues, wh…
Effect of disorder geometry on the critical force in disordered elastic systems
Vincent Démery, Vivien Lecomte, Alberto Rosso
We address the effect of disorder geometry on the critical force in disordered elastic systems. We focus on the model system of a long-range elastic line driven in a random landsca…
Velocity filtration and temperature inversion in a system with long-range interactions
Lapo Casetti, Shamik Gupta
Temperature inversion due to velocity filtration, a mechanism originally proposed to explain the heating of the solar corona, is demonstrated to occur also in a simple paradigmatic…
Classical Heisenberg spins with long-range interactions: Relaxation to equilibrium for finite systems
Julien Barré, Shamik Gupta
Systems with long-range interactions often relax towards statistical equilibrium over timescales that diverge with , the number of particles. A recent work [S. Gupta and D. Muka…
Non-equilibrium statistical mechanics of the heat bath for two Brownian particles
Caterina De Bacco, Fulvio Baldovin, Enzo Orlandini +1
We propose a new look at the heat bath for two Brownian particles, in which the heat bath as a `system' is both perturbed and sensed by the Brownian particles. Non-local thermal fl…
