Replica evolution of classical field in 4+1 dimensional spacetime toward real time dynamics of quantum field
Akira Ohnishi, Hidefumi Matsuda, Teiji Kunihiro +1
Real-time evolution of replicas of classical field is proposed as an approximate simulator of real-time quantum field dynamics at finite temperatures. We consider classical fie…

Shear viscosity of classical Yang-Mills field
Hidefumi Matsuda, Teiji Kunihiro, Berndt Müller +2
We investigate the shear viscosity of the classical Yang-Mills (CYM) field on a lattice by using the Green-Kubo formula, where the shear viscosity is calculated from the time-c…

Shear viscosity of classical fields in scalar theory
Hidefumi Matsuda, Teiji Kunihiro, Akira Ohnishi +1
We investigate the shear viscosity of massless classical scalar fields in the theory on a lattice by using the Green-Kubo formula. Based on the scaling property of the classi…
