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…
Mass-radius relation of Newtonian self-gravitating Bose-Einstein condensates with short-range interactions: II. Numerical results
P. H. Chavanis, L. Delfini
We develop the suggestion that dark matter could be a Bose-Einstein condensate. We determine the mass-radius relation of a Newtonian self-gravitating Bose-Einstein condensate with…
Mass-radius relation of Newtonian self-gravitating Bose-Einstein condensates with short-range interactions: I. Analytical results
Pierre-Henri Chavanis
We provide an approximate analytical expression of the mass-radius relation of a Newtonian self-gravitating Bose-Einstein condensate (BEC) with short-range interactions described b…
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…
