The existence of a corrugated surface is of great importance and ubiquity in biological
systems, exhibiting diverse dynamic behaviors. However, it has remained unclear whether …

The physics of activated escape of objects out of a metastable state plays a key role in
diverse scientific areas involving chemical kinetics, diffusion and dislocation motion in …

Multiple current reversals, where the direction of the net current changes multiple times with
the external load, is an anomalous transport property of a driven inertial Brownian particle …

Several dynamical systems in nature can be maintained out-of-equilibrium, either through
mutual interaction of particles or by external fields. The particle's transport and the transient …

The dynamics of nonlinear systems has emerged as an active interdisciplinary research field
at the interface of biology, chemistry, mathematics, physics and engineering. This article …

A nonlinear control is proposed for the exponential stabilization and synchronization of
chaotic behaviour in a model of Bose‐Einstein condensate (BEC). The active control …

It is well known that Brownian ratchets can exhibit current reversals, wherein the sign of the
current switches as a function of the driving frequency. We introduce a spatial discretization …

We consider two coupled particles moving along a periodic substrate potential with
negligible inertia effects (overdamped limit). Even when the particles are identical and the …

We investigate the transport dynamics of a cold atom exposed to a sawthooth-like optical
lattice potential subject to periodic δ-kicks. By means of the computed transport current, at …

The transport of N globally coupled Brownian motors driven by a periodic force with phase
disorder is investigated. An approximate theoretical analysis of the model is presented. The …
