多体RAGE定理

A many-body RAGE theorem

Jonas Lampart, Mathieu Lewin

摘要:

我们证明了N体量子系统中的一个推广的定理。结果表明,只有含有$0\leq n\leq N$粒子的系统的束缚态在长时间平均中持续存在。的限制制定了一个适当的弱拓扑结构的多体系统,这是由第二作者在以前的工作中介绍,是基于减少密度矩阵。这种拓扑结构与规范对易或反对易关系代数上的状态的弱-* 拓扑结构有关,我们给出了在这种情况下我们的主要结果的一个公式。

英文摘要:

We prove a generalized version of the RAGE theorem for N-body quantum systems. The result states that only bound states of systems with $0\leq n\leq N$ particles persist in the long time average. The limit is formulated by means of an appropriate weak topology for many-body systems, which was introduced by the second author in a previous work, and is based on reduced density matrices. This topology is connected to the weak-* topology of states on the algebras of canonical commutation or anti-commutation relations, and we give a formulation of our main result in this setting.
