Random transitions described by the stochastic Smoluchowski-Poisson system and by the stochastic Keller-Segel model
P. H. Chavanis, L. Delfini
We study random transitions between two metastable states that appear below a critical temperature in a one dimensional self-gravitating Brownian gas with a modified Poisson equati…
Phase transitions in self-gravitating systems and bacterial populations with a screened attractive potential
P. H. Chavanis, L. Delfini
We consider a system of particles interacting via a screened Newtonian potential and study phase transitions between homogeneous and inhomogeneous states in the microcanonical and…
Nonequilibrium dynamics of a stochastic model of anomalous heat transport: numerical analysis
L. Delfini, S. Lepri, R. Livi +2
We study heat transport in a chain of harmonic oscillators with random elastic collisions between nearest-neighbours. The equations of motion of the covariance matrix are numerical…
Nonequilibrium dynamics of a stochastic model of anomalous heat transport
S. Lepri, C. Mejia-Monasterio, A. Politi
We study the dynamics of covariances in a chain of harmonic oscillators with conservative noise in contact with two stochastic Langevin heat baths. The noise amounts to random coll…
Dynamical stability of systems with long-range interactions: application of the Nyquist method to the HMF model
P. H. Chavanis, L. Delfini
We apply the Nyquist method to the Hamiltonian Mean Field (HMF) model in order to settle the linear dynamical stability of a spatially homogeneous distribution function with respec…
Nonequilibrium Invariant Measure under Heat Flow
L. Delfini, S. Lepri, R. Livi +1
We provide an explicit representation of the nonequilibrium invariant measure for a chain of harmonic oscillators with conservative noise in the presence of stationary heat flow. B…
