Cooper pair polaritons in cold fermionic atoms within a cavity
Amaury Dodel, Alexander Pikovski, Igor Ermakov +4
We formulate a Bardeen-Cooper-Schriffer (BCS) theory of quasiparticles in a degenerate Fermi gas strongly coupled to photons in a optical cavity. The elementary photonic excitation…
On cold gases with anisotropic interactions
Alexander Pikovski
A cold gas of particles with anisotropic interactions of general form, due to a polarizing field, is studied. Special cases are atoms or molecules with dipole-dipole or quadrupole-…
Averaged collision and reaction rates in a two-species gas of ultracold fermions
Alexander Pikovski
Reactive or elastic two-body collisions in an ultracold gas are affected by quantum statistics. In this paper, we study ensemble-averaged collision rates for a two-species fermioni…
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…
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…
