Equation of state and Kosterlitz-Thouless transition temperature in two-dimensional Fermi gases: An analytical approach
Michael Klawunn
We study Fermi gases in two dimensions at low temperatures with attractive interactions. Analytical results are derived for the equation of state and the Kosterlitz-Thouless transi…
Polar molecules in bilayers with high population imbalance
Michael Klawunn, Alessio Recati
We investigate a dilute Fermi gas of polar molecules confined into a bilayer setup with dipole moments polarized perpendicular to the layers. In particular, we consider the extreme…
Non-local state-swapping of polar molecules in bilayers
A. Pikovski, M. Klawunn, A. Recati +1
The observation of significant dipolar effects in gases of ultra-cold polar molecules typically demands a strong external electric field to polarize the molecules. We show that eve…
The Fermi-polaron in two dimensions: Importance of the two-body bound state
Michael Klawunn, Alessio Recati
We investigate a single impurity interacting with a free two-dimensional atomic Fermi gas. The interaction between the impurity and the gas is characterized by an arbitrary attract…
Local atom-number fluctuations in quantum gases at finite temperature
M. Klawunn, A. Recati, L. P. Pitaevskii +1
We investigate the number fluctuations in small cells of quantum gases pointing out important deviations from the thermodynamic limit fixed by the isothermal compressibility. Both…
Interlayer superfluidity in bilayer systems of fermionic polar molecules
A. Pikovski, M. Klawunn, G. V. Shlyapnikov +1
We consider fermionic polar molecules in a bilayer geometry where they are oriented perpendicularly to the layers, which permits both low inelastic losses and superfluid pairing. T…
Two-dimensional scattering and bound states of polar molecules in bilayers
Michael Klawunn, Alexander Pikovski, Luis Santos
Low-energy two-dimensional scattering is particularly sensitive to the existence and properties of weakly-bound states. We show that interaction potentials with vanishing ze…
Bose-Fermi mixtures of self-assembled filaments of fermionic polar molecules
M. Klawunn, J. Duhme, L. Santos
Fermionic polar molecules in deep 1D optical lattices may form self-assembled filaments when the electric dipoles are oriented along the lattice axis. These composites are bosons o…
