Abstract
Based on the principles of thermodynamics of stability of the state of a homogeneous equilibrium system, the study demonstrates the fundamental link between the anharmonicity of the condensed state of matter and its physical properties. In this paper, the concepts based on the thermodynamics of the stability of the homogeneous state of the system have been developed in terms of anharmonism. Various forms of the stability determinant have been obtained depending on the stability coefficients and parameters characterizing the anharmonic properties of the system. The relation of all calorimetric coefficients with the complex anharmonicity of the condensed state has been determined. The dependences of the system phase stability determinant on the calorimetric coefficients have been obtained.
