Fokker–Planck equation and allowance for quantum fluctuations in the theory of excitons and biexcitons of high density
S. A. Moskalenko, A. Kh. Rotaru, Yu. M. Shvera
Abstract:
The methods of the quantum theory of fluctuations and damping are used
to obtain a master equation for the density matrix of Bogolyubov–coherent
excitons, photons, and biexcitons in solids. Glauber's $P$ representation is used to derive a Fokker–Planck equation for the system of coherent quasiparticles. Conditions are found for two-photon lasing biexcitons in the case of exciton-biexciton conversion. It is
shown that transition from the disordered to the ordered phase is equivalent to a phase transition of the first kind.
