This process is described by an interaction hamiltonian equal to "h-bar times a coupling constant times quantity sigma-plus times a plus quantity sigma-minus times a-dagger" in the Jaynes–Cummings model. The rate of this process is enhanced by a factor proportional to the Q-factor over the mode volume in the Purcell effect. The rate of this process is proportional to the third power of the fine structure constant. The product of the number density of atoms and the rate of this process is the (*) Einstein A coefficient. Systems that have at least three levels allow for population inversion to occur, in which the rate of this process exceeds that of its opposite, thus allowing the creation of a laser. For 10 points, name this process, which can occur in spontaneous and stimulated manners where a quantum of light is produced.
