Analysis of switching phenomena in a dense medium of two-level atoms.
The switching characteristics of a dense medium of two-level atoms is studied analytically. Switching depends on the ratio of the Rabi frequency to the strength of the near-dipole-dipole interaction. When this ratio is nearly one, an exact solution is obtained. Other values of the parameter are studied by the use of asymptotic analysis, and the conditions for switching are determined from an analytic expression.
