Lea Boßmann

I am working in the field of mathematical physics. My research focuses on the analysis of quantum many-body systems, in particular on the behaviour of dilute Bose gases.

My CV is available here.

I am currently on parental leave until October 2024.

 

Teaching Winter Semester 2024/25

I will be teaching the course Mathematical Quantum Mechanics. Here is a short description of the course in German and English.
