Non-adiabatic pumping in an oscillating-piston model
Maya Chuchem, Thomas Dittrich, Doron Cohen
We consider the prototypical "piston pump" operating on a ring, where a circulating current is induced by means of an AC driving. This can be regarded as a generalized Fermi-Ulam m…
Quantum dynamics in the bosonic Josephson junction
Maya Chuchem, Katrina Smith-Mannschott, Moritz Hiller +3
We employ a semiclassical picture to study dynamics in a bosonic Josephson junction with various initial conditions. Phase-diffusion of coherent preparations in the Josephson regim…
Quantum transport and counting statistics in closed systems
Maya Chuchem, Doron Cohen
A current can be induced in a closed device by changing control parameters. The amount of particles that are transported via a path of motion, is characterized by its expectati…
Occupation Statistics of a BEC for a Driven Landau-Zener Crossing
Katrina Smith-Mannschott, Maya Chuchem, Moritz Hiller +2
We consider an atomic Bose-Einstein condensate (BEC) loaded in a biased double-well trap with tunneling rate and inter-atomic interaction . The BEC is prepared such that all…
Phase-diffusion dynamics in weakly coupled Bose-Einstein condensates
Erez Boukobza, Maya Chuchem, Doron Cohen +1
We study the phase-sensitivity of collisional phase-diffusion between weakly coupled Bose-Einstein condensates, using a semiclassical picture of the two-mode Bose-Hubbard model. Wh…
Restricted quantum-classical correspondence and counting statistics for a coherent transition
Maya Chuchem, Doron Cohen
The conventional probabilistic point of view implies that if a particle has a probability to make a transition from one site to another site, then the average transport should…
