Starting from the fundaments of Quantum Mechanics for

electrons in materials, it is possible to build simpler methods that

keep the essence of the Physics as a starting point for Statistical

Physics models to reveal the emergent properties of materials

and the transitions between their phases.

In this course you will study:

- The properties of electrons in materials

- Formation of bands in crystals

- Effects of electron-electron interaction

- The role of symmetry

- The role of the thermodynamic limit

- Scaling laws and critical exponents

- Model systems and their ordered phases

- Renormalization group ideas
