Rabi oscillations in the dynamics of a fully quantized SQUID ring-electromagnetic field system

In this paper, a study based on a fully quantum-mechanical model for the coupling between a superconducting quantum interference device (an rf SQUID) and a single-mode quantized electromagnetic field is presented. The aim of this work is the prediction ofthe existence of some interesting phenomena, characterized by more than one Rabi frequency, occurring in the dynamics of the total coupled system when our analysis is developed inside a reduced low-lying energy 4D Hilbert subspace.
