Dynamics of matter-wave solitons in a ratchet potential
Dario Poletti, Tristram J. Alexander, Elena A. Ostrovskaya +2
We study the dynamics of bright solitons formed in a Bose-Einstein condensate with attractive atomic interactions perturbed by a weak bichromatic optical lattice potential. The lat…
Dissipationless Directed Transport in Rocked Single-Band Quantum Dynamics
Jiangbin Gong, Dario Poletti, Peter Hanggi
Using matter waves that are trapped in a deep optical lattice, dissipationless directed transport is demonstrated to occur if the single-band quantum dynamics is periodically tilte…
Many-body quantum ratchet in a Bose-Einstein condensate
Dario Poletti, Giuliano Benenti, Giulio Casati +1
We study the dynamics of a dilute Bose-Einstein condensate confined in a toroidal trap and exposed to a pair of periodically flashed optical lattices. We first prove that in the no…
