DOI: 10.1103/physreve.102.042114
Abstract: We numerically investigate negative mobility of an inertial Brownian particle moving in a periodic double-well substrate potential in the presence of a time-periodic force and a constant bias. For the deterministic case, we find from… read more here.

DOI: 10.1103/physrevlett.130.218201
Abstract: Absolute negative mobility (ANM) refers to the situation where the average velocity of a driven tracer is opposite to the direction of the driving force. This effect was evidenced in different models of nonequilibrium transport… read more here.
