| Popis: | The effect of the electromagnetic interaction between two neutral atoms is important for large separations where the London potential proportional toR-6 is altered and becomes the Casimir-Polder potential varying asR-7. It is shown that the interaction energy, for all separations, may be computed in a relatively simple manner by quantum electrodynamics with the aid of a reduced Hamiltonian involving transverse quanta alone. This Hamiltonian function is justified by an appeal to the dipole approximation in the Lagrangian. |
