Propagation of atomic matter waves inside an atom wave guide
摘要：
基于有效作用量原理，给出了弯曲原子波导中原子物质波传播的唯象描述。研究了原子物质波在引导势场（经典势场和量子势场）作用下的时空演化。本文简要讨论了波导中三能级原子物质波在外加控制光作用下的相干控制。空间周期性引导场（{ \it例如}）中的{ \it原子物质-波带隙结构}的概念，提出了碳豆荚内势（碳豆荚内势既能俘获原子又能俘获光）和{ \it光晶格带隙介质}。
英文摘要：
The phenomenological description of propagation of atomic matter waves inside a curved atom wave guide is presented based on the effective action principle. The evolutions in both temporal and spatial domains for the atomic matter wave in the presence of guiding potential fields (classical and quantized) are considered. The coherent control of three-level atomic matter waves in a wave guide by an external controlling light is briefly discussed. The concepts of {\it atomic matter-wave bandgap structure} in a spatially periodic guiding field ({\it e.g.}, the interior potential of carbon peapod which can trap both atoms and light) and {\it optical lattice bandgap medium} are suggested.
