Two—Point Function Reduction of Four—Point Amputated Functions and Transformations in FF and RA Basis in a Real—Time Finite Temperature NJL Model
《Communications in Theoretical Physics》2002年第6期685-692,共8页ZHOUBang-Rong 
国家自然科学基金
Based on a general analysis of Green functions in the real-time thermal field theory, we have proven that the four-point amputated functions in an NJL model in the fermion bubble diagram approximation behave like usua...

Explicit Proof of Equivalence of Two—Point Functions in the Two Formalisms of Thermal Field Theory
《Communications in Theoretical Physics》2002年第1期49-54,共6页ZHOUBang-Rong

We give an explicit proof of equivalence of the two-point function to one-loop order in the two formalisms of thermal theory based on the expressions in the real-time formalism and indicate that the key point of comp...
