Vibrational mechanics in an optical lattice: controlling transport via potential renormalization
A. Wickenbrock, P. C. Holz, N. A. Abdul Wahab +3
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-fr…
Current reversals in a rocking ratchet: the frequency domain
A. Wickenbrock, D. Cubero, N. A. Abdul Wahab +2
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 by varying…
Stationarity, soft ergodicity, and entropy in relativistic systems
David Cubero, Joern Dunkel
Recent molecular dynamics simulations show that a dilute relativistic gas equilibrates to a Juettner velocity distribution if ensemble velocities are measured simultaneously in the…
Stochastic resonance with weak monochromatic driving: gains above unity induced by high-frequency signals
Jesús Casado-Pascual, David Cubero, José Pablo Baltanás
We study the effects of a high-frequency (HF) signal on the response of a noisy bistable system to a low-frequency subthreshold sinusoidal signal. We show that, by conveniently cho…
