英文摘要: Spin-Orbit couplings exist widely in spin particle systems, which result in novelty dynamical properties of quantum systems, and are also the physics origins of the spin Hall effect, topological effect of many-body quantum systems, etc. We will focus on the control of spin-orbit coupling systems and the applications in quantum information theories in this project.(1)Analysis the dynamical properties of spin-orbit coupling systems, and find the effective control or optimal control methods on these systems;(2) Investigate the information flows and controls between simple quantum systems and special quantum many-body quantum systems;(3)Study how to detect and control properties of quantum many-body systems by simple quantum systems;(4)Study the applications of spin-orbit quantum systems in real quantum system based on the former theoretical studies, such as the quantum dots coupled by special quantum many-body systems. This project will benefit for the essential studies of spin-orbit coupling quantum systems, and find the effective way of control on the state, and extended the research work on the realizable applications of quantum information theory.
