Evaluation of high-order moments and cumulants in quantum spin systems
ORAL
Abstract
We present a numerical scheme for efficiently extracting the higher-order moments and cumulants of various operators on spin systems represented as tensor product states, for both finite and infinite systems. These quantities can be useful in the evaluation of phase transitions. Of particular interest is the application of this method to calculate the so-called Binder's Cumulant, which can be used to detect critical points even with small finite numerical calculations.
