The moving Fermi polaron
Johanna Hennebichler, Ruben Erlenstedt, Erich Dobler +5
The Fermi polaron, formed by an impurity interacting with a surrounding Fermi sea, exemplifies the canonical quasiparticle concept as a cornerstone in our description of quantum ma…
Observation of Temperature Effects on False Vacuum Decay in Atomic Quantum Gases
Riccardo Cominotti, Cosetta Baroni, Chiara Rogora +5
Temperature plays a crucial role in metastable phenomena, not only by contributing to determine the state (phase) of a system, but also ruling the decay probability to more stable…
Quantum mixtures of ultracold gases of neutral atoms
Cosetta Baroni, Giacomo Lamporesi, Matteo Zaccanti
After decades of improvements in cooling techniques of several atomic species and in finding methods for the achievement of stable quantum mixtures, the field is now ready for an e…
Progress toward a zero-magnetic-field environment for ultracold-atom experiments
Chiara Rogora, Riccardo Cominotti, Cosetta Baroni +4
The minimization of the magnetic field plays a crucial role in ultracold gas research. For instance, the contact interaction dominates all the other energy scales in the zero magne…
Fermionic quantum mixtures with tunable interactions
Rudolf Grimm, Cosetta Baroni
The topic of the present lecture notes are two-species quantum mixtures composed of a deeply degenerate Fermi gas and a second component, the latter being fermionic or bosonic. A k…
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…
Effect of Inter-Well Interactions on Non-Linear Beam Splitters for Matter-Wave Interferometers
Cosetta Baroni, Giacomo Gori, Maria Luisa Chiofalo +1
We study the non-linear beam splitter in matter-wave interferometers using ultracold quantum gases in a double-well configuration in presence of non-local interactions inducing int…
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…
