Mediated interactions between Fermi polarons and the role of impurity quantum statistics
Cosetta Baroni, Bo Huang, Isabella Fritsche +7
The notion of quasi-particles is essential for understanding the behaviour of complex many-body systems. A prototypical example of a quasi-particle, a polaron, is an impurity stron…
Stability and breakdown of Fermi polarons in a strongly interacting Fermi-Bose mixture
Isabella Fritsche, Cosetta Baroni, Erich Dobler +5
We investigate the properties of a strongly interacting imbalanced mixture of bosonic K impurities immersed in a Fermi sea of ultracold Li atoms. This enables us to expl…
Breathing Mode of a BEC Repulsively Interacting with a Fermionic Reservoir
Bo Huang, Isabella Fritsche, Rianne S. Lous +4
We investigate the fundamental breathing mode of a small-sized elongated Bose-Einstein condensate coupled to a large Fermi sea of atoms. Our observations show a dramatic shift of t…
Probing the Interface of a Phase-Separated State in a Repulsive Bose-Fermi Mixture
Rianne S. Lous, Isabella Fritsche, Michael Jag +4
We probe the interface between a phase-separated Bose-Fermi mixture consisting of a small BEC of K residing in a large Fermi sea of Li. We quantify the residual spatial…
Thermometry of a deeply degenerate Fermi gas with a Bose-Einstein condensate
Rianne S. Lous, Isabella Fritsche, Michael Jag +2
We measure the temperature of a deeply degenerate Fermi gas, by using a weakly interacting sample of heavier bosonic atoms as a probe. This thermometry method relies on the thermal…
Ultrafast many-body interferometry of impurities coupled to a Fermi sea
M. Cetina, M. Jag, R. S. Lous +8
The fastest possible collective response of a quantum many-body system is related to its excitations at the highest possible energy. In condensed-matter systems, the corresponding…
