Interaction of a two-level cyclic XY n-spin model with a two-mode cavity field in off-resonant states

The interaction of the XY n-spin cyclic model with a two-mode cavity field in the rotating-wave approximation is investigated in the framework of a generalized Jaynes-Cummings two-level system consisting of the vacuum state and a thermally averaged manifold of excited sates. Computation of the energ...
