Scanning gate experiments: from strongly to weakly invasive probes
R. Steinacher, C. Pöltl, T. Krähenmann +8
An open resonator fabricated in a two-dimensional electron gas is used to explore the transition from strongly invasive scanning gate microscopy to the perturbative regime of weak…
BCS-BEC crossover and the disappearance of FFLO-correlations in a spin-imbalanced, one-dimensional Fermi gas
F. Heidrich-Meisner, A. E. Feiguin, U. Schollwoeck +1
We present a numerical study of the one-dimensional BCS-BEC crossover of a spin-imbalanced Fermi gas. The crossover is described by the Bose-Fermi resonance model in a real space r…
Spin-charge separation in ultra-cold quantum gases
A. Recati, P. O. Fedichev, W. Zwerger +1
We investigate the physical properties of quasi-1D quantum gases of fermion atoms confined in harmonic traps. Using the fact that for a homogeneous gas, the low energy properties a…
Anomalous condensate fluctuations in strongly interacting superfluids
F. Meier, W. Zwerger
We show that the condensate occupation of a superfluid Bose liquid quite generally exhibits anomalously large fluctuations at finite temperatures. In three dimensions, the variance…
Josephson tunneling between weakly interacting Bose-Einstein condensates
F. Meier, W. Zwerger
Based on a tunneling Hamiltonian description, we calculate the Josephson, normal and interference currents between two Bose-Einstein condensates described by the Bogoliubov theory.…
Ginzburg-Landau theory of superconductors with short coherence length
S. Stintzing, W. Zwerger
We consider Fermions in two dimensions with an attractive interaction in the singlet d-wave channel of arbitrary strength. By means of a Hubbard-Stratonovich transformation a stati…
