Characterizing the many-body localization transition by the dynamics of diagonal entropy
Zheng‐Hang Sun, Jian Cui, Heng Fan
Abstract
The authors present a method of charactering many-body localization transition via the quench dynamics of diagonal entropy, as an experimentally feasible quantity. The critical point of many-body localization transition can be efficiently detected. The adopted scaling ansatz respects the Harris-Luck bound, and the scaling exponent can provide information for the universality class of many-body localization transition.
