Programmable cavity QED with a fiber-integrated atomic array
Stephan Roschinski, Johannes Schabbauer, Franz von Silva-Tarouca +3
Strong atom-photon interactions in optical cavities are a key resource for quantum information processing, quantum networking, and the exploration of quantum optical effects. Optic…
High-Speed NV Ensemble Magnetic Field Imaging via Laser Raster Scanning
Luca Troise, Nikolaj W. Hansen, Marvin Holten +4
We present a technique that uses an ensemble of nitrogen-vacancy (NV) centers in diamond to image magnetic fields with high spatio-temporal resolution and sensitivity. A focused la…
Emergent interaction-driven elliptic flow of few fermionic atoms
Sandra Brandstetter, Philipp Lunt, Carl Heintze +8
Hydrodynamics provides a successful framework to effectively describe the dynamics of complex many-body systems ranging from subnuclear to cosmological scales by introducing macros…
Observation of Cooper Pairs in a Mesoscopic 2D Fermi Gas
Marvin Holten, Luca Bayha, Keerthan Subramanian +5
Pairing is the fundamental requirement for fermionic superfluidity and superconductivity. To understand the mechanism behind pair formation is an ongoing challenge in the study of…
Observation of Pauli Crystals
Marvin Holten, Luca Bayha, Keerthan Subramanian +3
The Pauli exclusion principle is a fundamental law underpinning the structure of matter. Due to their anti-symmetric wave function, no two fermions can occupy the same quantum stat…
Observing the emergence of a quantum phase transition -- shell by shell
Luca Bayha, Marvin Holten, Ralf Klemt +6
Many-body physics describes phenomena which cannot be understood looking at a systems' constituents alone. Striking manifestations are broken symmetry, phase transitions, and colle…
Quantum scale anomaly and spatial coherence in a 2D Fermi superfluid
Puneet A. Murthy, Nicolò Defenu, Luca Bayha +4
Quantum anomalies are violations of classical scaling symmetries caused by quantum fluctuations. Although they appear prominently in quantum field theory to regularize divergent ph…
Anomalous breaking of scale invariance in a two-dimensional Fermi gas
Marvin Holten, Luca Bayha, Antonia C. Klein +3
The frequency of the breathing mode of a classical two dimensional Fermi gas in a harmonic confinement is fixed by the scale invariance of the Hamiltonian. Scale invariance is brok…
High temperature pairing in a strongly interacting two-dimensional Fermi gas
Puneet A. Murthy, Mathias Neidig, Ralf Klemt +7
We observe many-body pairing in a two-dimensional gas of ultracold fermionic atoms at temperatures far above the critical temperature for superfluidity. For this, we use spatially…
