An array of overdamped bistable oscillators with delay was studied numerically. Each site of the array is coupled directionally with the addition of white Gaussian noise. On the other hand, we compared the results with an array of coupled chain of experimental devices, also fed with Gaussian...

We have found, by varying two parameters, several stationary trajectories in a system consisting in many elastically coupled particles that are placed in a periodic ratchet potential on a ring. The system is assumed to be over-damped and driven by an external potential that is periodic both in...

We analyze a system consisting in many elastically coupled particles that are placed in a periodic ratchet potential on a ring. The system is assumed to be overdamped and driven by an external potential that is periodic both in space and time. The symmetries of the model allow to study the...
