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.
摘要
我们的实际数值结果表明，在由空间周期性光学晶格驱动的浅谐波阱中的玻色凝聚体的最新实验中，可以观察到δ驱动转子的基态和高阶量子共振。对于更强的约束，预计会出现相互作用导致的驱动谐波振荡器共振运动的破坏。
