Influence of a Medium on
Long-Range Inter-Particle Interactions: Molecular QED Theory
A. Salam
Department of Chemistry, Wake Forest University
Non-relativistic or molecular quantum electrodynamics (QED) has been
rigorously developed and applied with outstanding success to problems
in atomic, molecular and optical physics [1,2] such as single- and
multi-photon absorption, emission and scattering of light, optical
activity and chiroptical spectroscopy, non-linear and quantum optical
phenomena, and inter-particle interactions.
In this talk, an overview of the theory of molecular QED will be
given first, followed by application to a number of fundamental forces
acting between molecules, such as resonance energy transfer and van
der Waals dispersion, both in vacuum and in a medium [3-5]. The effect
of thermal radiation on these interactions will also be presented [6].
