| Sumario: | A set of nonlinear evolution equations describing the dynamics of atoms, molecules, and
photons in the course of stimulated atomic-molecular conversion in a Bose-Einstein condensate
is derived and studied in the mean-field approximation. It is shown that conversion can be
periodic or aperiodic in time, the rate of the process being determined, to a considerable extent,
by the initial density of particles and by the initial phase difference. Depending on initial conditions, various conversion modes can be realized. The possibility of stabilization of a special
state (of rest) of the system for nonzero initial number densities of particles is predicted. It is
pointed out that coherence of a Bose condensate of atoms, molecules, and photons predetermines the possibility of phase control of the conversion process. |
