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…
