在光学超晶格中操纵物质波
Manipulating matter waves in an optical superlattice
摘要：
我们研究了在一维光学超晶格中控制无相互作用的玻色-爱因斯坦凝聚体的可能性。我们的控制策略结合布洛赫振荡源于加速晶格和时间依赖性控制的超晶格参数。我们调查两个实验可行的方案，非常低和非常高的潜在深度。我们能够表现出广泛的控制使用超晶格控制参数的能带人口。通过这种分析，我们考虑了在超晶格结构中制备量子态的几个例子，这在规则晶格中可能难以实现。
英文摘要：
We investigate the potential for controlling a non-interacting Bose-Einstein condensate loaded into a one-dimensional optical superlattice. Our control strategy combines Bloch oscillations originating from accelerating the lattice and from time-dependent control of the superlattice parameters. We investigate two experimentally viable scenarios, very low and very high potential depths. We are able to exhibit a wide range of control over energy band populations using the superlattice control parameters. With this analysis we consider several examples of quantum state preparation in the superlattice structure that may be difficult to achieve in a regular lattice.
