27. Summary
We presented FULL quantum model (multimodel) to study how spontaneously initiated emission can get into stimulated mode
Scattered atoms form a squeezed state that can be viewed as a multi-component condensate.
Not only are we able to calculate the dynamics of mode occupation, but also the full statistics of scattered atoms.
Test ground for other (stochastic) methods
