Gradient structure and transport coefficients for strong particles

TL;DR

This paper introduces a solvable class of stochastic lattice gases called Strong Particles, where particles push away others when jumping, and explicitly computes their transport coefficients, enhancing understanding of their dynamics.

Contribution

It defines and analyzes Strong Particles, a new class of solvable lattice gases, and calculates their transport coefficients explicitly.

Abstract

We introduce and study a simple and natural class of solvable stochastic lattice gases. This is the class of \emph{Strong Particles}. The name is due to the fact that when they try to jump to an occupied site they succeed pushing away a pile of particles. For this class of models we explicitly compute the transport coefficients. We also discuss some generalizations and the relations with other classes of solvable models.
