Abstract

The groundbreaking investigation by Deutsch [Phys. Rev. A 43, 2046 (1991)PLRAAN1050-294710.1103/PhysRevA.43.2046] of how a closed many-body quantum system approaches thermal equilibrium is revisited. It is shown how to carry out some important steps that were missing in that paper. Moreover, the class of admitted systems is extended considerably.

摘要

重新审视了多伊奇[《物理评论A》43, 2046 (1991)PLRAAN1050 - 294710.1103/PhysRevA.43.2046]关于封闭多体量子系统如何趋近热平衡的开创性研究。展示了如何完成该论文中缺失的一些重要步骤。此外，所允许的系统类别有了相当大的扩展。
