## What is... Bose-Einstein condensation?

Talk by Marco Caporaletti

**Date:** 01.06.21 **Time:** 16.15 - 18.30 **Room:**

In the 1920s Bose and Einstein predicted that certain quantum many-particle systems at sufficiently low temperature exhibit what is now called Bose-Einstein condensation (BEC). In this phenomenon, a macroscopic fraction of the particles behaves collectively as one, with important consequences on the Physics of the system. Since its first experimental observation in 1995, much effort has been devoted in the Mathematical Physics community to the challenging problem of obtaining a rigorous proof of BEC for reasonable classes of systems. In this talk I will introduce the mathematical description of such systems and give an overview of (un)known results.
