摘要：

We study the effects of a uniform drift superposed on the motion of a tracer particle in a dynamical background. We consider a 1D lattice gas containing electrically neutral hard-core bulk particles and a charged tracer one subjected to an external electric field, which favors the tracer's hopping in a preferred direction. We show that the mean displacement of the tracer particle grows with time as approximately t1/2 due to interactions with the bulk particles.
