Pseudogap in the optical phonon spectra
– The energy spectrum of the quantum Klein-Gordon (KG) lattice is computed numerically for some model parameters that are relevant for optical phonon spectra. A pairing of the phonon states is found when the nonlinearity is significant which agrees with other studies on different quantum lattice models [1,2]. It results from the anharmonic energy contribution the magnitude of which is quantifie...
متن کاملOptical Properties and Optical Spectroscopy of Rare Earth Ions in Solids 2.1 Electron–Phonon Coupling in Solids
The Franck-Condon principle plays an important role in understanding the nature of optical transitions in laser-active ions in solids. According to this principle, absorption of a photon is an instantaneous process during which the nuclei are enormously heavy as compared to the electrons. In other words, the electronic transition occurs on a time scale that is short compared to nuclear motion, ...

متن کاملElectron–phonon interaction and optical spectra of metals
Observed optical reflectivity in the infrared spectral region is compared with theoretical predictions in a strongly coupled electron–phonon system. Starting from a Fröhlich Hamiltonian, the spectral functions and their temperature dependence are derived. A full analysis including vertex corrections leads to an expression for the optical conductivity σ(ω) which can be formulated in terms of the...
متن کاملStudies of Phonon Anharmonicity in Solids
Today our understanding of the vibrational thermodynamics ofmaterials at low temperatures is emerging nicely, based on the harmonic model in which phonons are independent. At high temperatures, however, this understanding must accommodate how phonons interact with other phonons or with other excitations. We shall see that the phonon-phonon interactions give rise to interesting coupling problems...
