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 ...

Current reversals in a rocking ratchet: the frequency domain
(American Physical Society, 2011)
Motivated by recent work [D. Cubero et al., Phys. Rev. E 82, 041116 (2010)], we examine the mechanisms which determine current reversals in rocking ratchets as observed when varying the frequency of the drive. We found ...
