INTRODUCTION TO THE PHYSICS OF MATTER (UNIT 2)

Molecular physics:
-Born-Oppenheimer approximation
-Diatomic molecules: rotovibrational energies; ground and exicted states in hydrogen molecular ion and in H2;
orbital molecular model
- Polyatomic molecules:ibridization
-Molecular spectra:rotational,vibration-rotation and electronic spectra;Raman effect

Solid state physics:
-Crystalline structures: Symmetries and Bravais lattices; reciprocal lattice; x-ray and neutron diffraction techniques; Bragg and Laue models
Crystal defects: Schottky and Frenkel defects; colour centre defects; dislocations
- Lattice vibrations: dispertion relation for monoatomic and diatomic linear chain, phonons
-Thermal properties: Einstein and Debye models
-Free electron
-Block Theorem: energy bands; metals and insulators
-Main properties of semiconductors
-An outline of the superconductivity
-Magnetic properties: diamagnetism, Langevin paramagnetism; quantistic theory of paramagnetism, Pauli paramagnetism; ferromagnetic and antiferromagnetic order
