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…
On the dynamics of the interaction between triggered active inclusions
Jean-Baptiste Fournier, Kévin Sin Ronia
In a one-dimensional elastic medium with finite correlation length and purely relaxational dynamics, we calculate the time dependence of the elastic force F(t) exchanged between tw…
Revisiting the flocking transition using active spins
A. Solon, J. Tailleur
We consider an active Ising model in which spins both diffuse and align on lattice in one and two dimensions. The diffusion is biased so that plus or minus spins hop preferably to…
Large deviations of Lyapunov exponents
Tanguy Laffargue, Khanh-Dang Nguyen Thu Lam, Jorge Kurchan +1
Generic dynamical systems have `typical' Lyapunov exponents, measuring the sensitivity to small perturbations of almost all trajectories. A generic system has also trajectories wit…
From adiabatic piston to non-equilibrium hydrodynamics
Ken Sekimoto, Antoine Fruleux, Ryoichi Kawai +1
Based on the new concept of the {\it momentum transfer deficiency due to dissipation} (MDD), the physical basis of the mechanism of ``adiabatic piston'' is explained. The implicati…
