Method to Obtain Quantum Dipole-Dipole Interaction by Calculating the Classical Radiation Power

doi:10.3969/j.issn.1007-2985.2012.06.011

Abstract

Abstract: This paper puts forward a general exact approach to obtain the quantum dipole-dipole interaction (DDI) between two two-level “atoms” in arbitrary nanostructures,in which the transfering rate of the DDI is analytically expressed as the difference between the two classical dipoles’ total radiation power and the sum of the two individual dipole’s radiation powers.The radiation power can be calculated by the finite-difference time-domain method.The validity of the method is tested for dipoles placed in vacuum and in an ideal planar microcavity and the calculated results agree well with the analytic solutions.

Key words: quantum dipole-dipole interaction, finite difference time domain method, radiation power
