Resonant Nonlinear Quantum Transport for a Periodically Kicked Bose Condensate

Our realistic numerical results show that the fundamental and higher-order quantum resonances of the ?-kicked rotor are observable in state-of-the-art experiments with a Bose condensate in a shallow harmonic trap, kicked by a spatially periodic optical lattice. For stronger confinement, interaction-induced destruction of the resonant motion of the kicked harmonic oscillator is predicted.
