Cavity Quantum Electrodynamics

Scientific American, 1993
Ever 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.1 Spontaneous emission is so fundamental that it is usually regarded as an inherent property of matter.

Quantum electrodynamics in a cavity

Physical Review A, 1982
The theory of interaction of atoms and molecules with radiation confined in a cavity is presented. The effect of the confinement on the field commutation relations is examined and the modified commutation relations are derived for an arbitrary cavity. It is shown that a canonical transformation on the minimal-coupling Hamiltonian for such systems leads

Cavity quantum electrodynamics

2022
Abstract 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

Reports on Progress in Physics, 2006
This paper reviews the work on cavity quantum electrodynamics of free atoms. In recent years, cavity experiments have also been conducted on a variety of solid-state systems resulting in many interesting applications, of which microlasers, photon bandgap structures and quantum dot structures in cavities are outstanding examples.

Cavity quantum electrodynamics

Optical Society of America Annual Meeting, 1991
Cavities are employed to effect various changes in the electromagnetic reservoir to which specimen atoms are coupled. Reservoirs of diverse character ranging from single-modelike to strongly frequency dependent can be realized. Generally speaking, atoms coupled to perturbed electromagnetic reservoirs display novel dynamics that can be of practical as ...

Cavity quantum electrodynamics

1999
In 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 ...
