The Stochastic Quantization Method in Phase Space and a New Gauge Fixing Procedure
R. Mochizuki
We study the stochastic quantization of the system with first class constraints in phase space. Though the Langevin equations of the canonical variables are defined without ordinar…

Gauge Independent Phase Structure of Gauged Nambu-Jona-Lasinio and Yukawa Models
K. -I. Kondo
We investigate the critical behavior of the gauged NJL model (QED plus 4-fermion interaction) and the gauged Yukawa model by use of the inversion method. By calculating the gauge-i…

Finite-Temperature and -Density QED: Schwinger-Dyson Equation in the Real-Time Formalism
K. -I. Kondo, K. Yoshida
Based on the real-time formalism, especially, on Thermo Field Dynamics, we derive the Schwinger-Dyson gap equation for the fermion propagator in QED and Four-Fermion model at finit…
