Parrondo's paradox refers to the paradoxical phenomenon of combining two losing
strategies in a certain manner to obtain a winning outcome. It has been applied to uncover …

We present the main results of the theory of Brownian motors obtained using the authors'
approach, in which a Brownian particle moving in a slightly fluctuating potential profile is …

We report on the observation of the ratchet effect—generation of direct electric current in
response to external terahertz radiation—in bilayer graphene, where inversion symmetry is …

Quantum directed transport can be realized in noninteracting, deterministic, chaotic systems
by appropriately breaking the spatiotemporal symmetries in the potential. In this work, the …

We report the observation of the terahertz-induced ratchet effect in graphene-based two-
dimensional (2D) metamaterials. The metamaterial consists of a graphite gate patterned with …

Using extensive numerical studies we demonstrate that absolute negative mobility of a
Brownian particle (ie the net motion into the direction opposite to a constant biasing force …

We consider the overdamped motion of a Brownian particle in an unbiased force field
described by a periodic function of coordinate and time. A compact analytical representation …

We reveal the mechanism of subdiffusion which emerges in a straightforward, one
dimensional classical nonequilibrium dynamics of a Brownian ratchet driven by both a time …

The directional motion of micro-and nanoparticles can be induced not only directly due to
the effect of forces with a nonzero average value, which set the direction of the motion, but …

Cytoplasmic dynein and kinesin are both microtubule-based molecular motors but are
structurally and evolutionarily unrelated. Under standard conditions, both move with …
