| 摘 要： | 囚禁在光学晶格中的旋量凝聚体由于其长的相干性和可调控性,使其成为时下热点的多比特量子计算的潜在候选载体,清楚地了解该体系的自旋和磁性的产生和调控就显得尤为重要.本文主要从理论上回顾了光晶格原子自旋链的磁性的由来和操控手段.从激光冷却原子出发,制备旋量玻色-爱因斯坦凝聚体,并装载进光晶格,最后实现原子自旋链,对整个过程的理论研究进行了综述;就如何产生和操控自旋激发进行了详细探讨,其中包括磁孤子的制备;讨论了如何将原子自旋链应用于量子模拟.对光学晶格中的磁激发研究将会对其在冷原子物理、凝聚态物理、量子信息等各方向的应用起指导性作用.

| Abstract: | Spinor condensates trapped in optical lattices have become potential candidates for multi-bit quantum computation due to their long coherence and controllability. But first, we need to understand the generation and regulation of spin and magnetism in the system. This paper reviews the origin and manipulation of the magnetism of atomic spin chains in optical lattices. The theoretical study of the whole process is described in this paper, including laser cooling, the spinor Bose-Einstein condensate preparations, the optical lattice, and the atomic spin chain. Then, the generation and manipulation of magnetic excitations are discussed, including the preparation of magnetic solitons. Finally, we discuss how to apply atomic spin chains to quantum simulation. The theoretical study of magnetic excitations in optical lattices will play a guiding role when the optical lattice is used in cold atomic physics, condensed matter physics and quantum information. |
