An ETH-ansatz-motivated environmental-branch approach to open quantum systems
Wen-ge Wang
In this paper, a method is developed for the study of a generic small central quantum system, which is locally coupled to an environment as a many-body quantum chaotic system that…

Statistical structural properties of many-body chaotic eigenfunctions and applications
Wen-ge Wang, Qingchen Li, Jiaozi Wang +1
In this paper, we employ a semiperturbative theory to study the statistical structural properties of energy eigenfunctions (EFs) in many-body quantum chaotic systems consisting of…

An operator-Weyl-symbol approach to eigenstate thermalization hypothesis
Xiao Wang, Wen-ge Wang
In this letter, by an approach that employs Weyl symbols for operators, a semiclassical theory is developed for the offdiagonal function in the eigenstate thermalization hypothesis…
