Aims

- Complements of quantum mechanics, in view of the understanding of material cohesion and their response to perturbations
- Elements of statistical physics, leading to the energy distribution of electrons and lattice vibrations in materials
- Phenomenological approach of material properties, based on thermodynamical constraints, and linked to the materials symmetry.

Main themes

This lecture presents the basics of materials physics (complements of quantum mechanics ; statistical physics ; symmetries and thermodynamics)
