Phase diagram of self-attracting systems
P. H. Chavanis, I. Ispolatov
Phase diagram of microcanonical ensembles of self-attracting particles is studied for two types of short-range potential regularizations: self-gravitating fermions and classical pa…
On first-order phase transition in microcanonical and canonical non-extensive systems
I. Ispolatov, E. G. D. Cohen
Two examples of Microcanonical Potts models, 2-dimensional nearest neighbor and mean field, are considered via exact enumeration of states and analytical asymptotic methods. In the…
Symmetry effects and equivalences in lattice models of hydrophobic interaction
G. M. Schütz, I. Ispolatov, G. T. Barkema +1
We establish the equivalence of a recently introduced discrete model of the hydrophobic interaction, as well as its extension to continuous state variables, with the Ising model in…
Correlation functions in decorated lattice models
I. Ispolatov, K. Koga, B. Widom
Occupation probabilities for primary-secondary-primary cell strings and correlation functions for primary sites of a decorated lattice model are expressed through the well-studied…
Phase Transition in a Traffic Model with Passing
I. Ispolatov, P. L. Krapivsky
We investigate a traffic model in which cars either move freely with quenched intrinsic velocities or belong to clusters formed behind slower cars. In each cluster, the next-to-lea…
Particle Systems with Stochastic Passing
I. Ispolatov, P. L. Krapivsky
We study a system of particles moving on a line in the same direction. Passing is allowed and when a fast particle overtakes a slow particle, it acquires a new velocity drawn from…
Persistence in systems with algebraic interaction
Iaroslav Ispolatov
Persistence in coarsening 1D spin systems with a power law interaction is considered. Numerical studies indicate that for sufficiently large values of the interaction ex…
