The paper examines the conditions for and mechanism of the onset of a nonequilibrium superradiant phase transition in a bulk semiconductor at room temperature in the strong coupling regime. Experimental data are analyzed, and the characteristic properties of this phase transition are compared with previously studied quantum phase transitions in ultracold gases in traps, ensembles of quantum dots, superconducting qubits, and some others. All the basic properties of the previously discovered collective state formed in the process of induced condensation of electron-hole pairs at room temperature are shown to correspond to those of the superradiant phase transition observed in other media.
