Estimating subsurface water mass changes with ground-based gravimetry
Isabelle Schmidt, Jackson Ang'ong'a, Peter Bauer-Gottwein +10
Gravitational force is proportional to the mass of an attracting body; therefore, changes in subsurface mass can be detected using gravimetry. In the near subsurface, mass variatio…
Universal spin dynamics in two-dimensional Fermi gases
Marco Koschorreck, Daniel Pertot, Enrico Vogt +1
Harnessing spins as carriers for information has emerged as an elegant extension to the transport of electrical charges. The coherence of such spin transport in spintronic circuits…
Collective modes of a two-dimensional spin-1/2 Fermi gas in a harmonic trap
Stefan K. Baur, Enrico Vogt, Michael Köhl +1
We derive analytical expressions for the frequency and damping of the lowest collective modes of a two-dimensional Fermi gas using kinetic theory. For strong coupling, we furthermo…
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…
Two-element Zeeman Slower for Rubidium and Lithium
G. Edward Marti, Ryan Olf, Enrico Vogt +2
We demonstrate a two-element oven and Zeeman slower that produce simultaneous and overlapped slow beams of rubidium and lithium. The slower uses a three-stage design with a long, l…
