We investigate a simple model corresponding to particles driven in opposite directions and interacting via a repulsive potential. The particles move off-lattice on a periodic strip and are subject to random forces as well. We show that this model-which can be considered as a continuum version of some driven diffusive systems-exhibits a paradoxical, new kind of transition called here "freezing by heating." One interesting feature of this transition is that a crystallized state with a higher…

Boltzmann and hydrodynamic description for self-propelled particles.

A homogeneous spontaneous motion emerges below a transition line in the noise-density plane, and is shown to be unstable against spatial perturbations, suggesting that more complicated structures should eventually appear.

Energy and phase transition in a horizontally vibrating granular system

The study focuses on the average energy of a monolayer of granular particles confined in a rectangular container. The container is shaken sinusoidally in a horizontal plane. The motion of every

Nonequilibrium statistical mechanics of a two-temperature Ising ring with conserved dynamics.

This study reveals complicated relaxation processes as well as a crossover between two very different steady-state regimes in the statistical mechanics of a one-dimensional Ising model in thermal equilibrium.

Critical and dynamical behavior of a driven diffusive lattice gas

In this work, a detailed analysis of the critical behavior of the Katz, Lebowitz, and Spohn (KLS) [Phys. Rev. B 28, 1665 (1983)] model is performed. This model considers a lattice gas of density ρ0

Mesoscopic theory for fluctuating active nematics

The term active nematics designates systems in which apolar elongated particles spend energy to move randomly along their axis and interact by inelastic collisions in the presence of noise. Starting

Instabilities, nucleation, and critical behavior in nonequilibrium driven fluids: theory and simulation

The main subject of this thesis rests on the study ---at different levels of description--- of instabilities in systems which are driven, i.e., maintained far from equilibrium by an external forcing.

Characterization of a freezing/melting transition in a vibrated and sheared granular medium

We describe experiments on monodisperse spherical particles in an annular cell geometry, vibrated from below and sheared from above. This system shows a freezing/melting transition such that under

Mobile-to-clogging transition in a Fermi-like model of counterflowing particles.

In this paper we propose a generalized model for the motion of a two-species self-driven objects ranging from a scenario of a completely random environment of particles of negligible excluded volume

Nonequilibrium pattern formation in strongly interacting driven colloids.

It is shown that stripe-like segregation occurs also in asymmetric mixtures and an additional compression/expansion effect in the stripes composed of the small/large particles and the relaxation into the striped steady state is studied.

We present a brief overview of the current understanding of temporal and spatio-temporal chaos, both termed weak turbulence according to the context [1]. The process which allows one to reduce the
