Field and dipole squeezing in a driven degenerate Λ quantum-beat system

The properties of field squeezing and atomic dipole squeezing in a coherent-microwave field driven degenerate Lambda quantum-beat system were theoretically investigated. Numerical calculations indicate that the driving microwave may enhance or suppress both dipole squeezing and cavity-field squeezing, depending on the atomic energy level splitting and the microwave Rabi frequency.
