Photon phonon interaction
WebDec 4, 2024 · Fan and coworkers investigated the photon-phonon atomic coherence interactions for various phase transitions in Eu 3+:BiPO 4 crystals. Different atomic coherence spectral interactions can be probed by changing the time gates. The authors show that increased phonon dressing led to a destructive interaction of atomic … Webconcentrations of electrons and holes their interaction with optical phonons is screened. Theoretical calcula-tions of the role of screening of the electron–phonon interaction in cooling of the electron–hole plasma have been mainly restricted to numerical methods (see, for example, [2]). In this study, analytical expressions for
