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…
Quantum ratchet control - harvesting on Landau-Zener transitions
L. Morales-Molina, S. Flach, J. B. Gong
We control the current of a single particle quantum ratchet by designing ramping schemes for experimentally accessible control parameters. We harvest on Landau-Zener transitions be…
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…
Inhomogeneous soliton ratchets under two ac forces
Luis Morales-Molina, Franz G. Mertens, Angel Sanchez
We extend our previous work on soliton ratchet devices [L. Morales-Molina et al., Eur. Phys. J. B 37, 79 (2004)] to consider the joint effect of two ac forces including non-harmoni…
