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 lin…
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 representatio…
Quantum Field Theories with Tensor Renormalization Group
Shinichiro Akiyama, Yoshinobu Kuramashi, Yusuke Yoshimura
We report recent progress on the application of the tensor renormalization group (TRG) to quantum field theories pursued by the Tsukuba group. We explain how to treat the scalar, f…
Phase transition of four-dimensional lattice theory with tensor renormalization group
Shinichiro Akiyama, Yoshinobu Kuramashi, Yusuke Yoshimura
We investigate the phase transition of the four-dimensional single-component theory on the lattice using the tensor renormalization group method. We have examined the hopping…
Restoration of chiral symmetry in cold and dense Nambu--Jona-Lasinio model with tensor renormalization group
Shinichiro Akiyama, Yoshinobu Kuramashi, Takumi Yamashita +1
We analyze the chiral phase transition of the Nambu--Jona-Lasinio model in the cold and dense region on the lattice developing the Grassmann version of the anisotropic tensor renor…
Tensor renormalization group approach to four-dimensional complex theory at finite density
Shinichiro Akiyama, Daisuke Kadoh, Yoshinobu Kuramashi +2
Tensor network is an attractive approach to field theory with negative sign problem. The complex theory at finite density is a test bed for numerical algorithms to verify the…
