It is well established that application of an oscillatory excitation with zero time-average but temporal asymmetry can yield net drift. To date this temporal symmetry breaking and net drift has been explored primarily in the context of point particles, nonlinear optics, and quantum systems. Here, we present two new experimental systems where the impact of temporally asymmetric force excitations can be readily observed with mechanical motion of macroscopic objects: (1) solid centimeter-scale…

Quantum resonances and rectification in ac-driven ratchets

Classical ratchets have been recently successfully realized using cold atoms in driven optical lattices. Here we study the current rectification of the motion of a quantum particle in a periodic

Antiperiodic oscillations

In contrast to the isolated solutions presently known, this work reports infinite hierarchies of antiperiodic waveforms that can be tuned continuously and that form wide spiral-shaped stability phases in the control parameter plane.

Rectification of current in ac-driven nonlinear systems and symmetry properties of the Boltzmann equation

We study rectification of a current of particles moving in a spatially periodic potential under the influence of time-periodic forces with zero mean value. If certain time-space symmetries are

Aperiodic capillary electrophoresis method using an alternating current electric field for separation of macromolecules

A novel way to make a similar transition in the area of separation techniques, capillary electrophoresis (CE) in particular, by suggesting several new mechanisms that could induce this effect in a sufficiently strong AC electric field.
