Cavity quantum electrodynamics
2022Abstract Inhibition and enhancement of spontaneous emission rate, first proposed by Purcell, is discussed in terms of altered density-of-modes in various types of solid-state cavities and the Purcell factor is derived for two-level atomic system.

Cavity quantum electrodynamics
1999In Chap. 14, we have interpreted spontaneous emission in terms of the irreversible emission of a photon into the free space modes of the electromagnetic field, accompanied by a transition of the atom from an upper to a lower electronic state. As already hinted at in that chapter, this description of spontaneous emission is not general, and spontaneous ...

Cavity Quantum Electrodynamical Metamaterials
Conference on Lasers and Electro-Optics, 2020We introduce the concept of designing new optical materials from “meta-atoms” comprised of matter ultra-strongly-coupled to an optical cavity. Such “strongly-coupled” materials can have surprising properties, such as metallic behavior at low frequencies.

Cavity Quantum Electrodynamics
Physics Today, 1989Ever since Einstein demonstrated that spontaneous emission must occur if matter and radiation are to achieve thermal equilibrium, physicists have generally believed that excited atoms inevitably radiate. Spontaneous emission is so fundamental that it is usually regarded as an inherent property of matter.

Cavity Quantum Electrodynamics: Coherence in Context
Science, 2002Modern cavity quantum electrodynamics (cavity QED) illuminates the most fundamental aspects of coherence and decoherence in quantum mechanics. Experiments on atoms in cavities can be described by elementary models but reveal intriguing subtleties of the interplay of coherent dynamics with external couplings.

CAVITY QUANTUM ELECTRODYNAMICS AT OPTICAL FREQUENCIES
Optics and Photonics News, 1992Quantum electrodynamics (QED) tells us that the electromagnetic field is, on a mode-by-mode basis, quantized according to the harmonic oscillator model. Each mode is ascribed a lowest energy (or dark) state possessing one half quanta of non-removable energy plus an infinite ladder of equally spaced excited states accessed through the addition or ...

Optical cavity quantum electrodynamics
CLEO/Europe - EQEC 2009 - European Conference on Lasers and Electro-Optics and the European Quantum Electronics Conference, 2009Cavity quantum electrodynamics (cavity QED) deals with the investigation and the targeted control of novel radiation phenomena that occur when light and matter interact in the confined space between nearby and highly reflecting mirrors. A famous paradigm for such phenomena is the enhancement of the rate of spontaneous emission of an excited atom or ...
