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…
Anomalous loss behavior in a single-component Fermi gas close to a -Wave Feshbach resonance
K. Welz, M. Gerken, B. Zhu +4
We theoretically investigate three-body losses in a single-component Fermi gas near a -wave Feshbach resonance in the interacting, non-unitary regime. We extend the cascade mode…
Ultrafast Many-Body Dynamics in an Ultracold Rydberg-Excited Atomic Mott Insulator
V. Bharti, S. Sugawa, M. Mizoguchi +7
We report the observation and control of ultrafast non-equilibrium many-body electron dynamics in Rydberg-excited spatially-ordered ultracold atoms created from a three-dimensional…
Floquet Hamiltonian Engineering of an Isolated Many-Body Spin System
Sebastian Geier, Nithiwadee Thaicharoen, Clément Hainaut +6
Controlling interactions is the key element for quantum engineering of many-body systems. Using time-periodic driving, a naturally given many-body Hamiltonian of a closed quantum s…
Heteronuclear Efimov scenario with positive intraspecies scattering length
Juris Ulmanis, Stephan Häfner, Rico Pires +4
We investigate theoretically and experimentally the heteronuclear Efimov scenario for a three-body system that consists of two bosons and one distinguishable particle with positive…
Universality of weakly bound dimers and Efimov trimers close to Li-Cs Feshbach resonances
J. Ulmanis, S. Häfner, R. Pires +3
We study the interspecies scattering properties of ultracold Li-Cs mixtures in their two energetically lowest spin channels in the magnetic field range between 800 G and 1000 G. Cl…
Observation of Efimov Resonances in a Mixture with Extreme Mass Imbalance
R. Pires, J. Ulmanis, S. Häfner +4
We observe two consecutive heteronuclear Efimov resonances in an ultracold Li-Cs mixture by measuring three-body loss coefficients as a function of magnetic field near a Feshbach r…
Observation of interspecies Li-Cs Feshbach resonances
M. Repp, R. Pires, J. Ulmanis +4
We report on the observation of nineteen interspecies Feshbach resonances in an optically trapped ultracold Bose-Fermi mixture of ^{133}Cs and ^{6}Li in the two energetically lowes…
