Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | A theory of thermodynamic fluctuations of electromagnetic field in slightly
absorbing media is developed using the quantum electrodynamics –
method of Γ -operators – without phenomenology. The hypothesis offered
by Yury L. Klimontovich is under consideration. The necessity of correct
consideration of photon-photon correlation functions is shown. The results
are compared with the ones obtained with the help of standard theory
based upon fluctuation-dissipation theorem (FDT). The latter results are
shown to have no field of application at least for the case of thermally excited
media of the atoms described with two-level model. |
