There is a vast array of further Quantum Field Theory texts, many of them with redeeming features. One of the first great successes of QED was the explanation of the Lamb Shift in atomic hydrogen [ 5 ], made by Bethe [ 6 ], Kroll and Lamb [ 7 ], French and Weisskopf [ 8 ]. Lasers are one application that has come out of the study of quantum optics. Get the plugin now. Remove this presentation Flag as Inappropriate I Don't Like This I like this Remember as a Favorite.

It takes a unique route to through the subject, focussing initially on particles rather than elds. Download Share Share. The pair potential is ﬁrst divided into short- and long-range regions, with the exchange–repulsion energy being the major contribution to the inter-action energy in the former distance regime. Quantum optics is a branch of quantum physics that focuses primarily on the behavior of light, or photons. Actions. called quantum electrodynamics, or shortly QED. At the level of quantum optics, the behavior of individual photons has a bearing on the outcoming light, as opposed to classical optics, which was developed by Sir Isaac Newton.
