Field Effect on the Excitonic Luminescence in CsI

Abstract

The electric field ionization of the self-trapped exciton is studied and the results are interpreted in terms of the Schottky effect theory. Though the possibility of internal radiationless transitions is not excluded, the idea of thermal ionization of the self-trapped exciton finds experimental support.

Spin light of relativistic electrons in neutrino fluxes

“…Comparing (3) with corresponding spectra of a neutrino [5,6] or an electron [15] in nonmoving matter we conclude that the number s = ±1 distinguishes two possible electron spin states.…”

“…Within these studies, in particular, a new mechanism of electromagnetic radiation that can be emitted by a neutrino with nonzero magnetic moment propagating in dense matter was proposed and termed the spin light of neutrino in matter (SLν) [1]. The quantum theory of the SLν was first revealed in our studies [5,6] ( see also [7]) within implication of the so called "method of wave equations exact solutions" that implies use of exact solutions of modified Dirac equations that contain the corresponding effective potentials accounting for the matter influence on neutrinos [5,6,[8][9][10][11][12][13].…”

“…It follows that there is a reasonable increase of the emitted photon energy in case of the relativistic motion of the emitters (the electrons). Using expressions for the amplitude (8) and the wave functions of the initial and final electrons (6), and also for the emitted photon energy (11) we get for the SLe ν total rate and power,…”

Neutrino quantum decoherence engendered by neutrino radiative decay

“…In [20] the radiative decay is considered between vacuum neutrino mass states that are not stationary in the electron media. In our studies we are working within the formalism that we have used for the quantum theory of the spin light of neutrino [22][23][24] where transitions occur between the neutrino stationary states in matter.…”

“…In equation (23) we used the fact that A µ f = 0 and that the initial state is Gaussian with regard to the field variables. Inserting (23) into (22) after some algebra gives…”
