Vg. Vaks et Vv. Kamyshenko, ON THE THEORY OF OPEN SYSTEMS - STATISTICAL THERMODYNAMICS AND DECOMPOSITION TYPE PHASE-TRANSITIONS FOR THE MODEL OF AN ALLOY UNDER IRRADIATION, Physics letters. A, 177(3), 1993, pp. 269-274
We discuss a generalization of statistical thermodynamics to the open
system case using as an example the model of an alloy under irradiatio
n. The statistical properties of the stationary states are described w
ith the use of generalized thermodynamic potentials and ''quasi-intera
ctions'' determined from the master equation for probabilities. Method
s for solution of this equation are illustrated by mean-field type cal
culations of correlators, thermodynamic potentials and phase diagrams
for disordered alloys.
