QUANTUM DYNAMICS OF A SINGLE COOPER-PAIR BOX WITH A SINGLE-MODE CAVITY FIELD

We consider a single Cooper-pair box biased by a classical voltage and also irradiated by a single-mode quantized field. We investigate the quantum dynamics of the Cooper-pair box and show that the collapse and revival phenomena can exist in this system, which is sensitive to the detuning between the Josephson energy E_J and cavity field frequency ω.
