Vibrational mechanics in an optical lattice: controlling transport via potential renormalization
(American Physical Society, 2012)
We demonstrate theoretically and experimentally the phenomenon of vibrational resonance in a periodic potential, using cold atoms in an optical lattice as a model system. A high-frequency (HF) drive, with a frequency ...

Control of transport in two-dimensional systems via dynamical decoupling of degrees of freedom with quasiperiodic driving fields
(American Physical Society, 2012)
We consider the problem of the control of transport in higher-dimensional periodic structures by applied ac fields. In a generic crystal, transverse degrees of freedom are coupled, and this makes the control of motion ...
