Title: Properties of self-organized criticality in the driven Lorentz channel due to synchronisation
Abstract:The talk focuses on particle transport in a finite harmonically driven Lorentz gas in a channel geometry. Aspects of self-organisation are revealed by tracking the motion of the injected particles at the level of elementary cells comprising the channel. Namely, when the driven scatterers periodically open ballistic corridors the particles synchronise their motion with this dynamic opening giving rise to intermittent dynamics. As a result the distribution of the number of cells crossed without a change in the direction of motion exhibits an algebraic tail. This property is robust with respect to the geometrical characteristics of the system and variability of the initial conditions, an attribute reminiscent of self-organised criticality (SOC). This fact demonstrates that intermittency is a sufficient condition for the emergence of long-range (critical) correlations.
