Algebraic infection of charge correlations of a classical electrolyte at the critical point of the liquid-gas transition
Angel Alastuey, Subir Das
We consider a classical Two-Component Plasma analog of the Restricted Primitive Model of electrolyte, where the hard-core interaction is replaced by a soft differentiable potential…
Force microscopy cantilevers locally heated in a fluid: temperature fields and effects on the dynamics
Basile Pottier, Ludovic Bellon
Atomic force microscopy cantilevers are often, intentionally or not, heated at their extremity. We describe a model to compute the resulting temperature field in the cantilever and…
Thermal critical dynamics from equilibrium quantum fluctuations
Irénée Frérot, Adam Rançon, Tommaso Roscilde
We show that quantum fluctuations display a singularity at thermal critical points, involving the dynamical exponent. Quantum fluctuations, captured by the quantum variance (I.…
Path integral derivation and numerical computation of large deviation prefactors for non-equilibrium dynamics through matrix Riccati equations
Freddy Bouchet, Julien Reygner
For many non-equilibrium dynamics driven by small noise, in physics, chemistry, biology, or economy, rare events do matter. Large deviation theory then explains that the leading or…
Optimal mean first-passage time of a Brownian searcher with resetting in one and two dimensions: Experiments, theory and numerical tests
Felix Faisant, Benjamin Besga, Artyom Petrosyan +2
We study experimentally, numerically and theoretically the optimal mean time needed by a Brownian particle, freely diffusing either in one or two dimensions, to reach, within a tol…
Dynamics of information erasure and extension of Landauer's bound to fast processes
Salambô Dago, Ludovic Bellon
Using a double-well potential as a physical memory, we study with experiments and numerical simulations the energy exchanges during erasure processes, and model quantitatively the…
