Abstract

In the Coulomb gauge formulation of quantum electrodynamics, elementary particles interact via two mechanisms: (1) An instantaneous Coulomb interaction and (2) a retarded interaction mediated by transverse photons. In the present chapter we shall study the electromagnetic interaction between just two particles (e.g., electrons) or composed particles (atoms, molecules, quantum dots, mesoscopic particles, etc.). In all cases, it is assumed that the probability density distributions of the two particles do not overlap in space. When composed particles come so close to each other that the tails of the density distributions begin to overlap electrons can move from one particle to the other by quantum mechanical tunneling, and if the distance is made sufficiently small one cannot in a meaningful manner treat the global system as a two-particle object
