... In exact resonance (δ = 0) the states would be degenerate in the case without coupling. However, a classical field couples the two bare states which mix and form the dressed states. Instead of a crossing a pronounced anti-crossing is observed. The splitting is proportional to the Rabi-frequency and ...

The average occupancy of single particle states is indeed very small, as in the case of an ideal dilute gas obeying the M-B distribution. ...
