Controlling the Population Imbalance of a Bose-Einstein Condensate by a Symmetry-Breaking Driving Field
Luis Morales-Molina, Jiangbin Gong
Nonlinear Floquet states associated with a symmetry-breaking driving field are exploited to control the dynamics of a Bose-Einstein condensate in a double-well potential. The popul…
Resonant ratcheting of a Bose-Einstein condensate
Luis Morales-Molina, Sergej Flach
We study the rectification process of interacting quantum particles in a periodic potential exposed to the action of an external ac driving. The breaking of spatio-temporal symmetr…
Periodically driven Quantum Ratchets: Symmetries and Resonances
S. Denisov, L. Morales-Molina, S. Flach +1
We study the quantum version of a tilting and flashing Hamiltonian ratchets, consisting of a periodic potential and a time-periodic driving field. The system dynamics is governed b…
Quantum resonances and rectification of driven cold atoms in optical lattices
S. Denisov, L. Morales-Molina, S. Flach
Classical Hamiltonian ratchets have been recently successfully realized using cold atoms in driven optical lattices. Here we study the current rectification of the motion of a quan…
