Many body quantum mechanics

We develop techniques, both analytical (QFT methods, varational ansatzs,…) and numerical (Matrix Product States,  Exact diagonalization, Machine Learning,…) to solve different problems in many body quantum mechanics. Our favorite are light-matter in extreme coupling regimes, non-linear quantum optics, topological models and magnetism driven by quantum light.

We do it because we want to understand how and wich matter properties are modified when it is strongly coupled to the quantum fluctuations of the electromagnetic field.  Our calculations are also useful to design quantum-light emitters, nanophotonics devices or for building quantum information processors.
