EXACTLY SOLUBLE MODEL OF ATOM-PHONON COUPLING SHOWING PERIODIC DECAY AND REVIVAL
We present a simple quantum model for a two-level atom interacting with initially coherent radiation. The mean atomic excitation energy, evaluated in exact closed form, exhibits rapid oscillations which periodically collapse and regenerate. The exact behaviour of the atom in a thermal field is also...

| Izvleček: | We present a simple quantum model for a two-level atom interacting with initially coherent radiation. The mean atomic excitation energy, evaluated in exact closed form, exhibits rapid oscillations which periodically collapse and regenerate. The exact behaviour of the atom in a thermal field is also derived. © 1981. |
