Theoretical physics

Many physical systems exhibit phase transitions, i.e. abrupt changes in their properties when a parameter crosses a threshold value: a fluid changes from a liquid to a gaseous state at the evaporation temperature, a magnet loses its magnetic properties at the Curie temperature, and so on.

In this course, you will learn tools and ideas developed by statistical physics to deal with "complex systems". These tools can be used in different contexts, including economics and social sciences where the modelling of collective phenomena, crises, panics, and discontinuities, is more necessary than ever.
