Finite-size scaling analysis of eigenstate thermalization
arXiv:2103.01539 · doi:10.1016/j.aop.2022.168761
Abstract
We study the fluctuations of eigenstate expectation values in a microcanonical ensemble. Assuming the eigenstate thermalization hypothesis, an analytical formula for the finite-size scaling of the fluctuations is derived. The same problem was studied by Beugeling et al. [Phys. Rev. E 89, 042112 (2014)]. We compare our results with theirs.
