Phonon representations ( lattice / spectrum )
The gap between the nonlocalized latticephonon description and the localized Einstein oscillator treatment is filled by transforming the phonon Hamiltonian back to the particle variables. The particle-coordinate, normalized, wave function for the phonon vacuum state is exhibited. The lattice phonon is a spatially nonlocalized concept. There are circumstances, however, that require its combinati...
متن کاملCO2 phonon mode renormalization using phonon-assisted energy up-conversion
Molecular dissociation under incident light whose energy is lower than the bond dissociation energy has been achieved through multi step excitation using a coupled state of a photon, electron, and multimode-coherent phonon as known as the dressed photon phonon (DPP). Here, we have investigated the effects of the DPP on CO2, a very stable molecule with high absorption and dissociation energies, ...
متن کاملPhonon spectrum in a plasma crystal.
The Fourier spectra of longitudinal and transverse waves corresponding to random particle motion were measured in a two-dimensional plasma crystal. The crystal was composed of negatively charged microspheres immersed in a plasma at a low gas pressure. The phonons were found to obey a dispersion relation that assumes a Yukawa interparticle potential. The crystal was in a nonthermal equilibrium, ...
متن کاملEffect of phonon-phonon interactions on localization.
We study the heat current J in a classical one-dimensional disordered chain with on-site pinning and with ends connected to stochastic thermal reservoirs at different temperatures. In the absence of anharmonicity all modes are localized and there is a gap in the spectrum. Consequently J decays exponentially with system size N. Using simulations we find that even a small amount of anharmonicity ...
متن کاملCoupling between phonon-phonon and phonon-impurity scattering: A critical revisit of the spectral Matthiessen’s rule
The spectral Matthiessen’s rule is commonly used to calculate the total phonon scattering rate when multiple scattering mechanisms exist. Here we predict the spectral phonon relaxation time τ of defective bulk silicon using normal mode analysis based on molecular dynamics and show that the spectral Matthiessen’s rule is not accurate due to the neglect of the coupling between anharmonic phonon-p...
