具有初始关联的短时动力学
Short time dynamics with initial correlations
摘要：
关联系统的短时动力学受初始关联的强烈影响，从而在非马尔可夫动力学方程中产生额外的碰撞积分。如果初始状态是热平衡，这是一个重要的一致性准则，发现这两个积分的精确取消。给出了相关能随时间演化的解析结果，并与分子动力学模拟（MD）进行了比较。
英文摘要：
The short-time dynamics of correlated systems is strongly influenced by initial correlations giving rise to an additional collision integral in the non-Markovian kinetic equation. Exact cancellation of the two integrals is found if the initial state is thermal equilibrium which is an important consistency criterion. Analytical results are given for the time evolution of the correlation energy which are confirmed by comparisons with molecular dynamics simulations (MD).
