光晶格的快速无扰展开
Fast Frictionless Expansion of an Optical Lattice
摘要:
研究了动态变间距光晶格(手风琴晶格)的快速无摩擦膨胀。我们设计了一个膨胀轨道,产生一个最终状态相同的初始状态,一个无关的相位因子。讨论了附加力和非线性相互作用对快速无摩擦膨胀的影响。
英文摘要:
We investigate fast frictionless expansion of an optical lattice with dynamically variable spacing (accordion lattice). We design an expansion trajectory that yields a final state identical to the initial state up to an irrelevant phase factor. We discuss the effect of additional force and nonlinear interaction on the fast frictionless expansion.
