Laser spectroscopy and cooling of Yb+ ions on a deep-UV transition
Hendrik M. Meyer, Matthias Steiner, Lothar Ratschbacher +2
We perform laser spectroscopy of Yb+ ions on the 4f14 6s 2S_{1/2} - 4f13 5d 6s 3D[3/2]_{1/2} transition at 297 nm. The frequency measurements for 170Yb+, 172Yb+, 174Yb+, and 176Yb+…
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…
