Sandro Wimberger, Riccardo Mannella, Oliver Morsch, and Ennio Arimondo
TL;DR
This paper demonstrates that quantum resonances in a delta-kicked Bose condensate can be observed experimentally, and predicts their destruction under stronger confinement due to interactions.
Contribution
It provides numerical evidence for observable quantum resonances in Bose condensates and predicts interaction effects on resonance stability.
Findings
Quantum resonances are observable in Bose condensates with optical lattice kicks.
Stronger confinement leads to destruction of resonant motion due to interactions.
Numerical results align with potential experimental observations.
Abstract
Our realistic numerical results show that the fundamental and higher-order quantum resonances of the delta-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.
