Phys. Rev. A 75, 043803 (2007) [4 pages]Quantum tunneling through potentials induced by vacuum-multiparticle interactionsReceived 18 October 2006; published 3 April 2007 The vacuum cavity mode induces a potential barrier and a well when an ultraslow excited atom enters the interaction region so that it can be reflected or transmitted with a certain probability. We demonstrate here that a slow-velocity excited particle tunnels freely through a vacuum electromagnetic field mode filled with N−1 ground state atoms. The reason for this is the trapping of the moving atom into its upper state due to multiparticle influences and the corresponding decoupling from the interaction with the environment such that the emitter does not “see” the induced potentials. © 2007 The American Physical Society URL:
