Query: Dark states in multi-mode multi-atom Jaynes-Cummings systems   We consider a system consisting of N two-level atoms inside an M-mode
degenerate, driven cavity. We discuss the formation of dark states in this
system and derive the conditions required for the observation of the dark-state
anti-resonance in the cavity emission.
