Cosmological two-fluid thermodynamics

Abstract

We reveal unifying thermodynamic aspects of so different phenomena as the cosmological electron-positron annihilation, the evaporation of primordial black holes with a narrow mass range, and the ``deflationary'' transition from an initial de Sitter phase to a subsequent standard Friedmann-Lema\^ıtre-Robertson-Walker begin (FLRW) behavior.
