Phase structure analysis of 2d lattice CP(1) model with term using tensor renormalization group method
Hayato Aizawa, Shinji Takeda, Yusuke Yoshimura
We investigate the phase structure of a two-dimensional lattice CP(1) model with a term. In particular, we aim to identify a critical region expected to exist along a …

Phase structure analysis of CP(1) model with term by tensor renormalization group
Hayato Aizawa, Shinji Takeda, Yusuke Yoshimura
We analyze the phase structure of 2d lattice CP(1) model with term by using the bond-weighted tensor renormalization group method. We propose a new tensor network representati…
