Abstract
To simulate thermalizing systems at long times, the most straightforward approach is to calculate the thermal properties at the corresponding energy. In a quantum many-body system of size N, for local observables and many initial states, this approach has an error of O(1/N), which is reminiscent of the finite-size error of the equivalence of ensembles. In this paper, we propose a simple and efficient numerical method so that the simulation error is of higher order in 1/N. This finite-size error scaling is proved by assuming the eigenstate thermalization hypothesis.
