A two-dimensional Fermi liquid with attractive interactions
B. Fröhlich, M. Feld, E. Vogt +4
We realize and study an attractively interacting two-dimensional Fermi liquid. Using momentum resolved photoemission spectroscopy, we measure the self-energy, determine the contact…
Radio frequency spectra of Feshbach molecules in quasi-two dimensional geometries
Stefan K. Baur, Bernd Fröhlich, Michael Feld +4
The line shape of radio frequency spectra of tightly bound Feshbach molecules in strong transverse confinement can be described by a simple analytic formula that includes final sta…
Attractive and repulsive Fermi polarons in two dimensions
Marco Koschorreck, Daniel Pertot, Enrico Vogt +3
The dynamics of a single impurity in an environment is a fundamental problem in many-body physics. In the solid state, a well-known case is an impurity coupled to a bosonic bath, f…
Observation of a pairing pseudogap in a two-dimensional Fermi gas
Michael Feld, Bernd Fröhlich, Enrico Vogt +2
Pairing of fermions is ubiquitous in nature and it is responsible for a large variety of fascinating phenomena like superconductivity, superfluidity of He, the anomalous rotati…
Scale invariance and viscosity of a two-dimensional Fermi gas
Enrico Vogt, Michael Feld, Bernd Fröhlich +3
We investigate the collective excitations of a harmonically trapped two-dimensional Fermi gas from the collisionless (zero sound) to the hydrodynamic (first sound) regime. The brea…
Radiofrequency spectroscopy of a strongly interacting two-dimensional Fermi gas
Bernd Fröhlich, Michael Feld, Enrico Vogt +3
We realize and study a strongly interacting two-component atomic Fermi gas confined to two dimensions in an optical lattice. Using radio-frequency spectroscopy we measure the inter…
