摘　　要：基于非马尔科夫量子态扩散(NMQSD)方法研究含有X方向Kaplan-Shekhtman-Entin-Wohlman-Aharony(KSEA)相互作用的系统中混合非马尔科夫/马尔科夫环境、单一非马尔科夫/马尔科夫环境下几何量子失协的动力学演化。结果表明:含有X方向KSEA相互作用的系统中混合非马尔科夫环境下几何量子失协的提高比单一非马尔科夫环境更高;处在同一纠缠态和不同强度的X方向KSEA相互作用时,系统的几何量子失协在混合非马尔科夫环境中获得更好的恢复;马尔科夫环境下单一库的情况比混合的情况要好。Based on NMQSD(non-Markovian quantum state diffusion)method,this paper studies containing dynamical evolution of geometric quantum discord in a system with X direction Kaplan-Shekhtman-Entin-Wohlman-Aharony(KSEA)interaction in a hybrid non-Markovian/Markovian environment and a single non-Markovian/Markovian environment.The results show that the geometric quantum discord in the hybrid non-Markovian environment is higher than that in the single non-Markovian environment.When interaction with X direction KSEA in the same initial state and different directions of intensity,the geometric quantum discord of the system achieves better recovery in a hybrid non-Markov environment.And we find that the single bath in the Markovian environment is better than the hybrid bath.
