Vacuum Rabi oscillation

From Wikipedia, the free encyclopedia

A vacuum Rabi oscillation is a damped oscillation of an initially excited atom coupled to an electromagnetic resonator or cavity in which the atom alternately emits photon(s) into a single-mode electromagnetic cavity and reabsorbs them. The atom interacts with a single-mode field confined to a limited volume V in an optical cavity.[1][2][3] Spontaneous emission results as a consequence of coupling between the atom and the vacuum fluctuations of the cavity field. The vacuum Rabi frequency is given by

where is the location of the atom, for plane-wave fields, is the field polarization, is the electric field per photon, and is the dipole matrix element.
