Transport phenomena in spatially periodic systems far from thermal equilibrium are
considered. The main emphasis is put on directed transport in so-called Brownian motors …

Ratchets are nonequilibrium devices that produce directional motion of particles from
nondirectional forces without using a bias, and are responsible for many types of biological …

Quantum ratchets are Brownian motors in which the quantum dynamics of particles induces
qualitatively new behavior. We review a series of experiments in which asymmetric …

We address the problem of controlling chaotic motion and deterministic directed transport in
inertia ratchets. We employ a recursive backstep** nonlinear control technique to control …

We present the effect of current reversals in inertial chaotic ratchets, without changing a
control parameter. This novel situation can occur when we have multiple coexisting …

Diodes are a basic component of electrical circuits to control the flow of charge, and
geometric diodes (GDs) are a special class that can operate using ballistic or quasi-ballistic …

We address the problem of the chaotic transport of point particles and rigid dimers in an
asymmetric periodic ratchet potential. When the inertial term is taken into account, the …

Here a straightforward procedure to characterize electronic resonances in arbitrary coupled
open or closed nano and micro structures–formed by cavities (or billiards) connected by …

Geometric diodes (GDs) represent an unconventional class of diode that use an asymmetric
geometry to produce an asymmetric current response. Unlike most traditional diodes, they …

The impulsive synchronization problem of two identical chaotic ratchets is investigated in
this paper. We demonstrate that the impulsive method to control directed transport is …
