Bose Fermi mixtures at large (but finite) mass ratios (C03)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 273811115

In fundamental models of many-body physics the coupling between fermions and bosons leads to a rich phase structure and dynamical behavior. Our project aims to explore the dynamics of quantum impurities in a fermionic medium (Fermi polarons) by means of ultracold mixtures of fermionic and bosonic atoms at extreme mass imbalance. In a concerted theoretical-experimental approach we will study how the mixture behaves at varying interactions and increasing boson densities and how signatures of Anderson orthogonality catastrophe can be revealed.
