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…
Equation of State of Ultracold Fermions in the 2D BEC-BCS Crossover Region
I. Boettcher, L. Bayha, D. Kedar +7
We report the experimental measurement of the equation of state of a two-dimensional Fermi gas with attractive s-wave interactions throughout the crossover from a weakly coupled Fe…
Observation of the Berezinskii-Kosterlitz-Thouless Phase Transition in an Ultracold Fermi Gas
P. A. Murthy, I. Boettcher, L. Bayha +7
We experimentally investigate the first-order correlation function of a trapped Fermi gas in the two-dimensional BEC-BCS crossover. We observe a transition to a low-temperature sup…
Observation of pair condensation in the quasi-2D BEC-BCS crossover
M. G. Ries, A. N. Wenz, G. Zürn +7
The condensation of fermion pairs lies at the heart of superfluidity. However, for strongly correlated systems with reduced dimensionality the mechanisms of pairing and condensatio…
