Loop-TNR analysis of CP(1) model with theta term
Hikaru Kawauchi, Shinji Takeda
The phase structure of the two dimensional lattice CP(1) model in the presence of the term is analyzed by tensor network methods. The tensor renormalization group, which is a s…
Phase structure analysis of CP(N-1) model using Tensor renormalization group
Hikaru Kawauchi, Shinji Takeda
The phase structure of the lattice CP() model in two dimensions is analyzed by the tensor renormalization group (TRG) method. We focus on the case and compare the numeri…
Tensor renormalization group analysis of CP(N-1) model
Hikaru Kawauchi, Shinji Takeda
We apply the higher-order tensor renormalization group to the lattice CP() model in two dimensions. A tensor network representation of the CP() model in the presence of t…
Tensor renormalization group analysis of model in two dimensions
Hikaru Kawauchi, Shinji Takeda
We apply the higher order tensor renormalization group to lattice CP() model in two dimensions. A tensor network representation of CP() model is derived. We confirm that…
