Abstract

In the process of analyzing the axiomatic principles underlying statistical physics, when modeling the most probable stationary macrostates of non-ergodic closed systems, a forecast was obtained about a possible limitation purview of the main postulate, known as the principle of equiprobability for each realizable of microstate. It is assumed that if such a system is artificially brought into a thermodynamically equilibrium state, in particular, by filling it with thermal Planck radiation of the appropriate temperature, then the subsequent evolution of the state of this system can cause the appearance of stable polarization anisotropy of said radiation. The paper presents the successful results of a direct verification of aforesaid prognosis on a real physical installation. Important regularities characteristic of the applied mathematical model are noted.
