具有初始关联的量子粒子的平均场渐近行为

Mean Field Asymptotic Behavior of Quantum Particles with Initial Correlations

V. I. Gerasimenko

摘要:

本文研究了在初始关联存在下量子大粒子系统动力学演化的严格描述问题。其中一个发展的方法是在平均场标度极限的边缘观测量的框架内描述量子多粒子系统的演化。另一种方法基于在由单粒子边缘密度算符和关联算符指定的初始状态的情况下,在由广义量子动力学方程支配的单粒子边缘密度算符的框架内描述状态演化的可能性。

英文摘要:

In the paper we consider the problem of the rigorous description of the kinetic evolution in the presence of initial correlations of quantum large particle systems. One of the developed approaches consists in the description of the evolution of quantum many-particle systems within the framework of marginal observables in mean field scaling limit. Another method based on the possibility to describe the evolution of states within the framework of a one-particle marginal density operator governed by the generalized quantum kinetic equation in case of initial states specified by a one-particle marginal density operator and correlation operators.
