Anderson orthogonality scaling in the Rabi-driven heavy Fermi polaron
Michael Rautenberg, Tobias Krom, Eugen Dizer +6
The Anderson orthogonality catastrophe (AOC) is a paradigmatic many-body phenomenon in which a local perturbation induces a macroscopic response of a Fermi sea. We probe signatures…

The heavy Fermi polaron I: the Lithium-Cesium experiment
Michael Rautenberg, Tobias Krom, Eleonora Lippi +2
We present details of an experimental platform for studying Fermi polarons in a quantum-gas mixture. The system consists of about a thousand bosonic Cs impurities immersed…

An experimental platform for studying the heteronuclear Efimov effect with an ultracold mixture of Li and Cs atoms
Eleonora Lippi, Manuel Gerken, Stephan Häfner +10
We present the experimental apparatus enabling the observation of the heteronuclear Efimov effect in an optically trapped ultracold mixture of Li-Cs with high-resolutio…
