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 …
Grassmann tensor renormalization group for the massive Schwinger model with a term using staggered fermions
Hayato Kanno, Shinichiro Akiyama, Kotaro Murakami +1
We use the Grassmann tensor renormalization group method to investigate the Schwinger model with the staggered fermions in the presence of a periodic term in a b…
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…
Grassmann Tensor Renormalization Group for two-flavor massive Schwinger model with a theta term
Hayato Kanno, Shinichiro Akiyama, Kotaro Murakami +1
We investigate the Schwinger model with the massive staggered fermions in the presence of a periodic term, using the Grassmann tensor renormalization group. Than…
