The study of the fermion matrix spectral density in lattice quantum chromodynamics

[摘要] One has developed a new method which enables us to implement dynamical lattice fermions in Monte-Carlo Simulation; and it is simply based on the analytical formulation of the spectral density of the eigenvalues of the fermion matrix in the Kogut-Susskind scheme (4). The ratio of the determinants is predicted, then compared to the ratio calculated via the lanczos method (8). This is done in SU(3), in the chirally broken phase (9), in a 4[superscript4] latticeat P = 5.4, and in a 6[superscript4] lattice at P = 5.5.
