Propagator Of A Particle In A Photonic And A Magnetic Field And Evolution Of A Coherent State

E. G. Thrapsaniotis

Published 2004-01-09, updated 2004-11-06Version 2

In the present paper we study the interaction of a photonic field with a particle in a magnetic field. We use formalism similar to the Born-Oppenheimer approximation of molecular physics and we eliminate the photonic field variables by using a method related to the Berry phase to obtain an effective Hamiltonian and then extract the propagator of the particle. As an initial photonic state we assume a coherent one.

Comments: 12 pages, no figures. The present paper in the present form is not going to appear anywhere else. (Both versions are identical but in v2 the PaperId has been added.)
