It covers the basis required for quantum oscillator studies, single quantum harmonic oscillators, anharmonicity, oscillator populations in thermal equilibrium, quantum normal modes of vibration, damped harmonic oscillators, and vibrational spectroscopy.
The authors discuss how clusters are used as dissipative structures, and how they are subsequently interrelated with fluctuation-free volume models, percolation systems and the Anharmonicity Concept.
This coupling gives rise not only to strong anharmonicity for these phonon modes, but to a large non-linear electron-phonon coupling that explains the high [T.
We note that the thermal expansivity [Alpha] in Eq 4 is assumed to be caused by the anharmonicity of molecular vibrations.
