Phase Distribution Properties of a Moving Five-Level (Inverted Y)-Type Atom in the Presence of a Non-linear Medium.

In this paper, we study the nonlinear kerr effect in an inverted Y-type five-level atom moving through an open cavity. Under realistic parameters, we show that the kerr-medium affects the atomic population inversion and the phase probability distribution. A remarkable feature of the present model is that the kerr nonlinearity with a multi-level atom allows for a large detection of the system dynamics. These results offer new possibilities for controlling the system dynamics using the time-dependent interaction.
