Phenomenological theory of phase transitions of the nonlinear dissipative systems in quantum optics
Fa Ou, Tingwan Wu, Changfu Luan
Abstract
We present herein a phenomenological approach to the critical phenomena in the dissipative systems, including the optical bistable system, the laser, etc., which satisfies the principle of detailed balance. The substantial discussion is started from the standpoint that there are two kinds of critical points: stable and unstable, associated with the continuous and discontinuous transitions, respectively. In several senses this work would be a development of Landau's second order phase transition theory in equilibrium thermodynamics.
