Enhanced van der Waals interaction at interfaces
Using a recently obtained (general) formula for the interaction energy between an excited and a ground-state atom [Y. Sherkunov, Phys. Rev. A 75, 012705 (2007)], we consider the interaction energy between two such atoms near the interface between two media. We demonstrate that under the circumstances of the resonant coupling of the excited atom to the surface polariton mode of a vacuum-medium system the nonretarded atom*-atom interaction energy can be enhanced by (several) orders of magnitude in comparison with the van der Waals interaction energy of the two isolated atoms.
