Recent Developments in Quantum Optics

he quantum theory of light predicts many interesting effects that may seem counterintuitive or even impossible from a classical point of view. Several effects of this kind have been investigated at the Applied Physics Laboratory, including a new kind of interferometry, the cancellation of dispersion between two distant media, and a new type of phase associated with the electromagnetic field. So...

Application of Quantum Inequalities to Quantum Optics

We establish a connection between quantum inequalities, known from quantum field theory on curved spacetimes, and the degree of squeezing in quantum-optical experiments. We prove an inequality which binds the reduction of the electric-field fluctuations to their duration. The bigger the level of fluctuation-suppression the shorter its duration. As an example of an application of this inequality...

Theory of dressed states in quantum optics

The dual Dyson series [M.Frasca, Phys. Rev. A 58, 3439 (1998)], is used to develop a general perturbative method for the study of atom-field interaction in quantum optics. In fact, both Dyson series and its dual, through renormalization group methods to remove secular terms from the perturbation series, give the opportunity of a full study of the solution of the Schrödinger equation in differen...
