Introduction to the condensed matter physics The aim of studying the discipline: Standard topics such as crystalline structures, reciprocal space, free electrons, electronic band theory, phonons, semiconductor physics, semiconducting devices, and optical properties of solids are covered. The last few classes are monographic in nature and will offer an outline about superconductivity and superconducting devices.

The content of the course (9 lectures for 2 hours):
- Specific heat of solids: Boltzmann, Einstein and Debye theories. Shortcomings of Debye model.
- Electron in metals: Sommerfeld model. Specific heat in metals. Shortcomings of Sommerfeld model.
- Acoustic & optical phonons. X-ray diffraction. Bloch theorem.
- Insulator, semiconductor or metal. Electron transport properties in solids.
- Phenomenology of solids at low temperature. Superconductors.
- Electron-lattice interaction in solids and electron pairing in superconductors. Cooper pairs.
- Low-temperature superconductors in the excited states. Critical temperature and critical magnetic field.
