A deeper exploration of phonon physics covering lattice dynamics theory, phonon interactions, thermal transport, and spectroscopic techniques. This series bridges fundamental concepts with research-level understanding.
Building on the introductory concepts, this intermediate series delves into the theoretical framework of lattice dynamics, the role of anharmonicity in phonon interactions, and the connection between phonons and thermal transport properties. We also explore electron-phonon coupling and experimental techniques for probing phonon properties.
Formal development of lattice dynamics including the Born-von Kármán boundary conditions, dynamical matrix, and symmetry considerations in phonon calculations.
Understanding anharmonicity and phonon-phonon scattering processes including normal and umklapp processes, and their impact on material properties.
Phonon contribution to thermal conductivity derived from the Boltzmann transport equation, including scattering mechanisms and size effects.
The interaction between electrons and phonons, including the Fröhlich Hamiltonian, polaron formation, and the role in superconductivity.
Detailed treatment of experimental techniques for measuring phonon properties including neutron scattering, optical spectroscopy, and modern techniques.
