Abstract

A one-dimensional quantum four-state Potts model is investigated in the context of a tensor network algorithm based on the infinite matrix product state representation. The local order parameter and entanglement entropy are computed. The scalling for the maximal entropy of the four-state Potts model is unveiled. The critical points are given, which is well agree with other know results. Keywords-quantum phase transition; local order parameter; entanglement entropy; four-state Potts Model; central charge.
