摘要：We exposit the eigenvalue distribution of the lattice Dirac operator in Quantum Chromodynamics with two colors (i.e. two-color QCD).We explicitly calculate all the eigenvalues in the presence of finite quark chemical potential m for a given gauge configuration on the finite-volume lattice. We make use of the Banks-Casher relations to relate the eigenvalue spectral density to the physical observables. Assuming the strong coupling limit, we exhibit the numerical results for a random gauge configuration in two-color QCD implemented by the staggered fermion formalism and confirm that our results agree well with the known estimate quantitatively.
