Abstract

We show that the nonequilibrium atomic phase-space density (degeneracy) of a Bose gas confined in the off-resonant optical trap can be manipulated by means of the breathing modes of the atomic oscillations in the trap. This new phenomenon opens a possibility to control the onset of the Bose-Einstein condensation in the atomic cloud loaded in an optical trap. The effect arises from the instability of squeezing oscillations of atomic phase-space distribution, initiated by the nonadiabatic change of the optical potential. The manipulation of the degree of degeneracy of the atomic distribution is achieved by means of dynamical control of the squeezing parameters. The physical consequences of the proposed mechanism are discussed.
