    "abstract": "An effective Hamiltonian and equations of motion for treating both the\nresonant dipole-dipole interaction between two-level atoms and the resonant\natom-field interaction are derived, which can suitably be used for studying the\ninfluence of arbitrary dispersing and absorbing material surroundings on these\ninteractions. It is shown that the dipole-dipole interaction and the atom-field\ninteraction, respectively, are closely related to the real part and the\nimaginary part of the (classical) Green tensor. The theory is applied to the\nstudy of the transient behavior of two atoms that initially share a single\nexcitation, with special emphasis on the role of the two competing processes of\nvirtual and real photon exchange in the energy transfer between the atoms. To\nillustrate the powerfulness of the theory, specific results for the case of the\natoms being near a dispersing and absorbing microsphere are presented. In\nparticular, the regimes of weak and strong atom-field coupling are addressed.",
