摘要：

We discuss the possibility of inhibiting three-body recombination in atomic Bose-Einstein condensates via the application of resonant 2pi laser pulses. These pulses result in the periodic change in the phase of the molecular state by pi, which leads to destructive interference between the decay amplitudes following successive pulses. We show that the decay rate can be reduced by several orders of magnitude under realistic conditions.
