Sharp transition between ballistic and diffusive transport in PT-symmetric media

Abstract

Within the context of particle dynamics in low-dimensional systems, it is widely believed that the system’s structure predetermines the transport regime, e.g. ballistic, diffusive, or localized. More specifically, it is assumed that the existence of randomness within the system is necessary in order to observe diffusive or even localized transport[1]. On the other hand, in the absence of randomness, the transport is always assumed to be ballistic[2]. Hence, our findings of observing a rather sharp transition between ballistic and diffusive transport in time-independent, ordered media is most surprising and counter-intuitive.
