论文摘要
讨论了本征状热假说（ETH）。我们表明，ETH的一种常见公式并不一定意味着可观察到的许多身体量子系统的热量。为了获得热化，必须假设Eth-Ansatz中的规范或微域分布。更一般而言，可以在广义的ETH-ANSATZ中假设任何其他平均值，从而导致相应的平衡条件。
Eigenstate thermalization hypothesis (ETH) is discussed. We show that one common formulation of ETH does not necessarily imply thermalization of an observable of isolated many body quantum system. To get thermalization one has to postulate the canonical or microcanonical distribution in the ETH-ansatz. More generally, any other average can be postulated in the generalized ETH-ansatz which leads to a corresponding equilibration condition.
