T1 - Electric field commutation relation in the presence of a dipole atom
AU - Cresser, J. D.
PY - 1984

N2 - A calculation is presented of the unequal-time electric field commutation relation for an electromagnetic field coupled to a general multilevel atom treated as a nonrelativistic system. Use is made of the multipolar Hamiltonian in its dipole approximate form to describe the atom-field interaction. Contributions to the commutator in addition to the usual Pauli-Jordan results for a free field are found, and a physical interpretation of their origin is offered.
