Individual eigenvalue distributions of crossover chiral random matrices and low-energy constants of SU(2) × U(1) lattice gauge theory / Yamamoto, Takuya ; Nishigaki, Shinsuke M
We compute individual distributions of low-lying eigenvalues of a chiral random matrix ensemble interpolating symplectic and unitary symmetry classes by the Nyström-type method of evaluating the Fredholm Pfaffian and resolvents of the quaternion kernel. [...]

Entropy production and isotropization in Yang–Mills theory using a quantum distribution function / Tsukiji, Hidekazu ; Kunihiro, Teiji ; Ohnishi, Akira ; Takahashi, Toru T
We investigate the thermalization process from a glasma-like initial condition in a static box in terms of the Husimi–Wehrl (HW) entropy defined with the Husimi function, a quantum distribution function in a phase space. [...]
