Abstract:
The nonclassical properties of light and atomic dynamics are studied. The system
considered are two level atom interact with a quantized field in a high quality cavity,
which is recognized as the Jaynes-Cumming Model. The time- and intensity-dependent
atom-field coupling are applied to the system, with different initial field states and initial
atomic states. We also extend the system for three level atom in a cavity, and include the
dissipative mechanism in the system. We consider the laser driven three level atom in a
cavity coupled to a reservoir. Interesting effects of the transient coupling are analyzed
through the collapse-revival pattern in population inversion, while the nonclassicality of
cavity field is studied through the features in the evolution of Wigner function.
