We present a minimal model
of autonomous thermal motor, made of two interacting
Brownian particles, sitting on two periodic potentials, and kept at different temperatures. We show that such a system does not require ratchet potentials (with
, e.g., an asymmetric saw-tooth shape) in order to exhibit direct
transport, but presents a spontaneous symmetry breaking.
Both the dynamic and...

The collective dynamics of coupled units arranged on a random network exhibits complex dynamics ranging from synchronization to spatio-temporal chaos. It is often important to identify if perturbations spread across the network or are confined locally, in
the presence of quenched disorder. The spectrum of Lyapunov exponents, quantifying the sensitivity to perturbations, can be analyzed...

We demonstrate particle clustering on macroscopic scales in a coupled nonequilibrium system where two species of particles are advected by a fluctuating landscape and modify the landscape in the process. The phase diagram generated by varying the particle-landscape coupling, valid for all particle density and in both one and two dimensions, shows novel nonequilibrium phases. While particle...
