| contents | We develop a quantum reductive perturbation method (RPM), a generalization of classical RPM widely used in nonlinear wave theory, to derive a simplified model (i.e. quantum nonlinear Schrodinger equation) from fully quantum Heisenberg-Langevin-Maxwell equations describingphoton propagations in a coherent cold atomic gas. The result is used to discuss two-photon bound states and optical solitons in the gas. Though a specific system is considered, the quantum RPM established here is very general and can be applied to other complex quantum nonlinear problems. |
