Quantum stochastic operator equations are derived for inter-branch
exciton and polariton processes caused by acoustic phonon scattering.
The use of a fully quantum model combined with these recently developed
techniques predicts the presence of ``stimulated scattering'' terms,
and provides a sound basis for understanding the basis of the
approximations used in generating the equations. The theory is applied
to a model motivated by recent experiments where a stronger
photoluminescence signal from the high energy microcavity polariton
polariton is observed for low excitation powers, and also to an
experimental scheme designed to show evidence of the stimulated
scattering effect.
