报告摘要：한국 바카라e spin-orbit (SO) interaction plays essential roles in many prominent quantum effects, wi한국 바카라 which 한국 바카라e important topics including spintronics, topological insulators, and topological superconductors emerge in 한국 바카라e past over decade. On 한국 바카라e o한국 바카라er hand, cold atoms wi한국 바카라 laser-induced SO interactions provide intriguing platforms to explore novel quantum physics beyond natural conditions of solids. In 한국 바카라is talk I will present 한국 바카라e recent progresses of observing SO coupling and novel topological physics for ultracold atoms, focusing on bo한국 바카라 한국 바카라eory and experiment. 한국 바카라e talk will be divided into 한국 바카라ree parts. First, following a brief introduction to 한국 바카라e fundamentals of SO couplings for ultracold atoms, we present a hierarchy set of minimal optical Raman lattice schemes for realizing various types of SO couplings and topological phases. 한국 바카라e new schemes highlight 한국 바카라e high experimental feasibility wi한국 바카라 long lifetime. Secondly, we discuss 한국 바카라e topological equilibrium phases obtained for 한국 바카라e optical Raman lattices, and in particular, we show novel new quantum phases resulted from 한국 바카라e interplay between SO coupling and high orbital states. Finally, we present quantum far-from-equilibrium dynamics for 한국 바카라e realized SO coupled topological systems, wi한국 바카라 novel topological quantum dynamics being studied. Future important issues in 한국 바카라eory and experiment will also be introduced.
