Dynamical theory for modeling dipole-dipole interactions in a microcavity: The Green dyadic approach

A dynamical theory for modeling the dipole-dipole interaction in a microcavity is formulated using the Green dyadic approach. To our knowledge, this theory is one of the most general in many aspects of modeling the phenomenon. It accommodates an arbitrary number of layers adjacent to the cavity, constant but arbitrary dielectric properties within each layer, inclusion of retardation effects, ar...

Dipole-induced electromagnetic transparency.

We determine the optical response of a thin and dense layer of interacting quantum emitters. We show that, in such a dense system, the Lorentz redshift and the associated interaction broadening can be used to control the transmission and reflection spectra. In the presence of overlapping resonances, a dipole-induced electromagnetic transparency (DIET) regime, similar to electromagnetically indu...

Dipole-dipole interaction in a photonic crystal nanocavity

We put forward a general classical approach to obtain the quantum dipole-dipole interaction (DDI) between two two-level “atoms” in arbitrary nanostructures, in which the transfer 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...

Observation of dipole-dipole interaction in a degenerate quantum gas.

We have investigated the expansion of a Bose-Einstein condensate of strongly magnetic chromium atoms. The long-range and anisotropic magnetic dipole-dipole interaction leads to an anisotropic deformation of the expanding chromium condensate which depends on the orientation of the atomic dipole moments. Our measurements are consistent with the theory of dipolar quantum gases and show that a chro...
