In this thesis we study a nonequilibrium model that displays interesting and unusual phenomena. The analysed system consists of multiple probes locally interacting with driven colloids and trapped in a toroidal geometry. The effective forces between the probes break the action-reaction principle and these interactions induce, under particular conditions, stability of a crystal pattern, in which the probes are equidistant. In this thesis we explore the thermodynamic limit of such a system. Sending both the number of probes and the length of the ring to infinity it is possible to analyse how a perturbation on a hypothetic infinite crystal configuration perturbs such a system.

Abstract

In this thesis we study a nonequilibrium model that displays interesting and unusual phenomena. The analysed system consists of multiple probes locally interacting with driven colloids and trapped in a toroidal geometry. The effective forces between the probes break the action-reaction principle and these interactions induce, under particular conditions, stability of a crystal pattern, in which the probes are equidistant. In this thesis we explore the thermodynamic limit of such a system. Sending both the number of probes and the length of the ring to infinity it is possible to analyse how a perturbation on a hypothetic infinite crystal configuration perturbs such a system.
