Self-Energy Renormalization for Inhomogeneous Nonequilibrium Systems and Field Expansion via Complete Set of Time-Dependent Wave Functions
Y. Kuwahara, Y. Nakamura, Y. Yamanaka
The renormalization conditions of inhomogeneous systems of a quantum field under an external potential are studied, for both equilibrium and nonequilibrium scenarios and based on T…

From Classical Mechanics with Doubled Degrees of Freedom to Quantum Field Theory for Nonconservative System
Y. Kuwahara, Y. Nakamura, Y. Yamanaka
The -matrix structure of Green's functions is a common feature for the real-time formalisms of quantum field theory under thermal situations, such as the closed time pa…
