周期光晶格中相互作用玻色子的量子控制
Quantum Control of Interacting Bosons in Periodic Optical Lattice
摘要：
研究了光晶格中相互作用的两玻色子系统量子控制激发动力学中的避免交叉。具体来说，我们进行数值模拟的量子控制在这个系统中，驱动脉冲连接的受激拉曼绝热通道（STIRAP）的方式特性的未驱动的稳态。我们证明了这样的过渡的动力学是由混沌诱导避免交叉的影响，导致在绝热极限的最终结果的一致性损失。
英文摘要：
We study the avoided crossings in the dynamics of quantum controlled excitations for an interacting two-boson system in an optical lattice. Specifically, we perform numerical simulations of quantum control in this system where driving pulses connect the undriven stationary states in a manner characteristic of Stimulated Raman Adiabatic Passage (STIRAP). We demonstrate that the dynamics of such a transition is affected by chaos induced avoided crossings, resulting in a loss in coherence of the final outcome in the adiabatic limit.
