Contenuti
Classification of the states of matter. The solid crystal state: Crystal structures: Bravais lattices;unit The crystal symmetry; a structural view of crystal symmetry: bottom-up crystallography in molecular crystals; mathematical representation of crystal symmetry; reciprocal lattice; Bloch functions.
The electronic structure of molecular solids in a simplified form. The band structure; model systems; DOS.
Excited states of aggregates of molecules; Davydov splitting and Mini-Excitons; linear molecular crystals; Frenkel Excitons; physical dimers; Excimers; Band structure; Charge transfer excitons (CT); Exciton processes; Energy transfer.
Vibrations in solids: lattice dynamics; classic description of vibrations of a one dimensional monatomic chain; vibrations of a one dimensional biatomic chain; acoustic and optic branches; extension to a tridimensional crystal. Vibrations in molecular crystals and quantisation of the vibrational energy: Phonons. Quasi particles.
