Lattice Study of the High Density State of SU(2)-QCD
S. Muroya, A. Nakamura, C. Nonaka
We investigate high density state of SU(2) QCD by using Lattice QCD simulation with Wilson fermions. The ratio of fermion determinants is evaluated at each step of the Metropol is…
Study of the SU(2) High Density System with Wilson Fermion
S. Muroya, A. Nakamura, C. Nonaka
We investigate high density state of SU(2) QCD in the case of the Wilson fermions with Iwasaki improved action. Based on the Woodbery formula, the ratio of fermion determinants is…
Anisotropic Lattice and Its Application to Quark Gluon Plasma
Sunao Sakai, Atsushi Nakamura, Takuya Saito
We have studied the link-integration method for the improved actions. With this method the parameter in the medium to strong coupling regions is obtained. Effects of the self-e…
Complex diffusion Monte-Carlo method: test by the simulation of the 2D fermions
B. Abdullaev, M. Musakhanov, A. Nakamura
On the base of the diffusion Monte-Carlo method we develop the method allowing to simulate the quantum systems with complex wave function. The method is exact and there are no appr…
