A review of experimental methods for the generation and diagnostics of nonideal plasma and warm dense matter, which have become possible in recent years, is presented. The modern theoretical methods used to solve the problem of fluid-fluid phase transitions, including the plasma phase transition, are considered. Both the methods of quantum modeling and the results obtained within the framework of the chemical model of plasma are analyzed. Particular attention is paid to the phase transition in the warm dense hydrogen/deuterium at high pressures. The results for helium, aluminum, cesium, cerium, ionic and exciton plasmas, and some other substances are also considered.
