Nonradiative DKR processes: revisiting the theory. III. Multimode approaches
Mladen Georgiev, Fabio DeMatteis
We outline a method for dealing with the relaxation of optically excited NaI F centers in terms of a single effective frequency along a multimode coordinate. The 2s-2p mixing throu…

Nonradiative DKR processes: revisiting the theory. I. Unimode model
Fabio DeMatteis, Mladen Georgiev
We are revisiting the efficiency problem of DKR nonradiative transitions at local electronic centers in polarizable solids. Following a brief survey, we formulate the general rate…
