Abstract:
A study is made of a lumped system of emitters (nuclei, atoms, molecules)
with dipole-forbidden transitions between the first two energy levels in
interaction with a thermal electromagnetic field. Elimination of the
boson operators leads to an equation for the statistical operator of the
system of emitters describing two-photon interaction with the electromagnetic
field. A Fokker–Planck equation is also obtained and solved in the stationary case, and the result is used to investigate the equilibrium fluctuations in the populations of the atomic levels. The kinetics of the system and the statistical properties of the electromagnetic field are considered.
