In this research, by noting to the connection between the spontaneous emission rate and the imaginary part of the vector potential Green function, only by evaluating the vector potential Green function tensor of the system of the two slabs, an expression for the spontaneous emission rate is ...
We present a simple, efficient procedure to compute the spontaneous-emission rate from short-time finite-difference time-domain (FDTD) data of the electromagnetic field energy in microcavities of arbitrary geometry. As an illustration, we apply this procedure to two-dimensional photonic crystals. For...

If V is large enough, the mode spacing allows the emitter to couple to multiple modes, and the alteration ratio of the total spontaneous emission rate (F’) should include the sum of all these interactions, that is, F′=Γsp/Γsp,free=∑i=0N−1Fi. As V approaches infinity, the ...
In this paper, we focus on how the spontaneous-emission rate of a given excited atom is altered when this atom is placed inside a perfectly conducting wedge. We begin by briefly presenting the formalism upon which our calculations are founded, proceeding then to a long but straightforward ...
calculation method was the same as that reported by Van Wijk36. The difference in SPE intensity between two filters with successive wavelength cut-offs was used to calculate the photon emission of a particular wavelength range. The photon emission of the particular wavelength range was mathematically...
Using this result it is shown that the QED correction to the electron mass contains chiral terms which nevertheless are parity invariant. The spontaneous emission rate of a two-level atom is shown to increase in the medium. The spontaneously emitted radiation is partially polarized....
it was Einstein who first showed, on the basis of fundamental thermodynamic considerations, that in any inverted medium, spontaneous emission must occur at a rate that is proportional to the differential gain provided by thepopulation inversion. In other words,spontaneous emission noiseis an unavoidabl...
