Abstract

We observe the nonequilibrium system. By introducing the unitary transformation operator U15 (t, t') we defined the interaction representation, which made us able to derive the fundamental relation of quatum statistical physics. Using this equation we found the accurate expression for the statistical operator qH, in the Heisenberg representation, which enabled us to find out the general definition for nonequilibrium real-time Green's function.
