Manipulation of Cold Atomic Collisions by Cavity QED Effects
arXiv:quant-ph/0008001 · doi:10.1103/PhysRevLett.86.1474
Abstract
We show how the dynamics of collisions between cold atoms can be manipulated by a modification of spontaneous emission times. This is achieved by placing the atomic sample in a resonant optical cavity. Spontaneous emission is enhanced by a combination of multiparticle entanglement together with a higher density of modes of the modified vacuum field, in a situation akin to superradiance. A specific situation is considered and we show that this effect can be experimentally observed as a large suppression in trap-loss rates.
