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…
