Dipole-Dipole Coupling in the Presence of Dispersing and Absorbing
Bodies
D. -G. Welsch, Ho Trung Dung, L. Knöll
abstract: An effective Hamiltonian and equations of motion for treating both the
resonant dipole-dipole interaction between two-level atoms and the resonant
atom-field interaction are derived, which can suitably be used for studying the
influence of arbitrary dispersing and absorbing material surroundings on these
interactions. It is shown that the dipole-dipole interaction and the atom-field
interaction, respectively, are closely related to the real part and the
imaginary part of the (classical) Green tensor. The theory is applied to the
study of the transient behavior of two atoms that initially share a single
excitation, with special emphasis on the role of the two competing processes of
virtual and real photon exchange in the energy transfer between the atoms. To
illustrate the powerfulness of the theory, specific results for the case of the
atoms being near a dispersing and absorbing microsphere are presented. In
particular, the regimes of weak and strong atom-field coupling are addressed.
