Dn. Zubarev et Mv. Tokarchuk, NONEQUILIBRIUM THERMOFIELD DYNAMICS AND THE NONEQUILIBRIUM STATISTICAL OPERATOR METHOD .1. BASIC RELATIONS, Theoretical and mathematical physics, 88(2), 1991, pp. 876-893
Nonequilibrium thermofield dynamics is developed on the basis of the n
onequilibrium statistical operator. General transport equations are ob
tained in the thermofield representation, and the kinetic and hydrodyn
amic limiting cases are considered.
