The order parameter in binary mixtures
Phase transitions in a binary mixture are investigated by means of the collective variables method with a reference system. It is shown that the system is described with two sets of collective variables: η~k and ξ~k. The CV connected with the order parameter is η~k₌₀ in the case of the...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Phase transitions in a binary mixture are investigated by means of the
collective variables method with a reference system. It is shown that
the system is described with two sets of collective variables: η~k and ξ~k.
The CV connected with the order parameter is η~k₌₀ in the case of the
gas-liquid critical point as well as in the case of the mixing-demixing
phase transition. The particular form of η0 for each of these phenomena
can be determined by means of the relations between the microscopic
parameters,temperature, density and concentration of the system under
consideration. |
