研究了两个弱相互作用自旋耦合到分离玻色子浴中的动力学。在玻色子环境中，本文给出了任意谱密度函数的Born近似解析解，并指出在非马尔可夫情形下，共存的“寿命”更长或达到更大的值。
The dynamics of two weakly interacting spins coupled to separate bosonic baths is studied. An analytical solution in the Born approximation for arbitrary spectral density functions of the bosonic environments is found. It is shown that in the non-Markovian cases concurrence ‘lives’ longer or reaches greater values.
