Hierarchy of Multipolar Terms For Non Relativistic Moving Atoms in QED
Abdelbasset Felhi, Jean-Claude Guillot, Jaques Robert
In this article an hierarchy of terms in the expansion of the multipolar Hamiltonian for non relativistic moving atoms in QED is considered. The particular case of neutral composit…
