Metal-insulator transition in (2+1)-dimensional Hubbard model with tensor renormalization group
Shinichiro Akiyama, Yoshinobu Kuramashi, Takumi Yamashita
We investigate the doping-driven metal-insulator transition of the (2+1)-dimensional Hubbard model in the path-integral formalism with the tensor renormalization group method. We c…
Bulk-Sensitive Spin-Resolved Resonant Electron Energy-Loss Spectroscopy (SR-rEELS): Observation of Element- and Spin-Selective Bulk Plasmons
Shin-ichi Kimura, Taishi Kawabata, Hiroki Matsumoto +8
We have developed a spin-resolved resonant electron energy-loss spectroscopy (SR-rEELS) in the primary energy of 0.3--1.5 keV, which corresponds to the core excitations of -$3d…
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…
Phase transition of four-dimensional Ising model with tensor network scheme
Shinichiro Akiyama, Yoshinobu Kuramashi, Takumi Yamashita +1
We investigate the phase transition of the four-dimensional Ising model with two types of tensor network scheme, one is the higher-order tensor renormalization group and the other…
Phase transition of four-dimensional Ising model with higher-order tensor renormalization group
Shinichiro Akiyama, Yoshinobu Kuramashi, Takumi Yamashita +1
We apply the higher-order tensor renormalization group (HOTRG) to the four-dimensional ferromagnetic Ising model, which has been attracting interests in the context of the triviali…
