Loop-TNR analysis of CP(1) model with theta term


  • Mr. Hikaru KAWAUCHI

Primary authors



We analyze the CP(1) model using the Loop optimization for Tensor network renormalization (Loop-TNR). This method makes it possible to completely remove short-range entanglement at each coarse-graining step which can not be removed by the Tensor renormalization group. We compare the results of these methods in the presence of the theta term.
