Fermionic pairs, from the surface to the bulk
Sandra Brandstetter, Carl Heintze, Fabian Brauneis +4
Fermion pairing underlies collective quantum phenomena across widely different forms of matter. In extended systems such as ultracold Fermi gases, pairing is commonly understood th…
Few is different: deciphering many-body dynamics in mesoscopic quantum gases
Juergen Berges, Sandra Brandstetter, Jasmine Brewer +27
Emergent macroscopic descriptions of matter, such as hydrodynamics, are central to our description of complex physical systems across a wide spectrum of energy scales. The conventi…
Magnifying the Wave Function of Interacting Fermionic Atoms
Sandra Brandstetter, Carl Heintze, Paul Hill +3
Understanding many body systems is a key challenge in physics. Single atom resolved imaging techniques have unlocked access to microscopic correlations in ultracold quantum gases.…
Engineering single-atom angular momentum eigenstates in an optical tweezer
Philipp Lunt, Paul Hill, Johannes Reiter +3
We engineer angular momentum eigenstates of a single atom by using a novel all-optical approach based on the interference of Laguerre-Gaussian beams. We confirm the imprint of angu…
Realization of a Laughlin state of two rapidly rotating fermions
Philipp Lunt, Paul Hill, Johannes Reiter +3
We realize a Laughlin state of two rapidly rotating fermionic atoms in an optical tweezer. By utilizing a single atom and spin resolved imaging technique, we sample the Laughlin wa…
Optical Phase Aberration Correction with an Ultracold Quantum Gas
Paul Hill, Philipp Lunt, Johannes Reiter +3
We present an optical aberration correction technique for ultracold quantum gas experiments which directly utilizes the quantum gas as a wavefront sensor. The direct use of the qua…
