Nonequilibrium 2PI evolution of the O(N) model with longitudinal expansion
Yoshitaka Hatta, Akihiro Nishiyama
Motivated by the problem of thermalization in heavy-ion collisions, we present numerical simulations of the nonequilibrium evolution of the O(N) model in 1+2 dimensions with longit…
Towards thermalization in heavy-ion collisions: CGC meets the 2PI formalism
Yoshitaka Hatta, Akihiro Nishiyama
We propose to apply the two-particle irreducible (2PI) formalism to the problem of thermalization in heavy-ion collisions in the Color Glass Condensate (CGC) picture. We consider t…
Entropy Production in Gluodynamics in temporal axial gauge in 2+1 dimensions
Akihiro Nishiyama, Akira Ohnishi
Entropy production in non-Abelian gauge theory is discussed in the limit of vanishing classical fields. Based on the Kadanoff-Baym equation with the leading order self-energy in th…
Entropy production in 2D theory in the Kadanoff-Baym approach
Akihiro Nishiyama
We study non-equilibrium quantum dynamics of the single-component scalar field theory in 1+1 space-time dimensions on the basis of the Kadanoff-Baym equation including the next-to-…
