General Framework

The group has a long term interest in the theoretical description of the fundamental interactions (gravity, strong nuclear force, electroweak force) and their unification.

At the heart of this quest lies the idea that the universe is mathematically intelligible and that its fundamental physical description possesses compelling beauty, simplicity and elegance.

The concept of symmetry and how it is realized pervades much of the work carried out.

« Philosophy is written in this great book of the Universe which is continually open before our eyes but we cannot read it without having first learnt the language and the characters in which it is written. It is written in the language of mathematics and the characters are triangles, circles and other geometrical shapes without the means of which it is humanly impossible to decipher a single word; without which we are wandering in vain through a dark labyrinth. » Galileo Galilei, Il Saggiatore (1623)
