Optical lattices as a tool to study defect-induced superfluidity
Grigory E. Astrakharchik, Konstantin V. Krutitsky, Maciej Lewenstein +2
We study the superfluid response, the energetic and structural properties of a one-dimensional ultracold Bose gas in an optical lattice of arbitrary strength. We use the Bose-Fermi…

Gapped spectrum in pair-superfluid bosons
G. E. Astrakharchik, R. E. Zillich, F. Mazzanti +1
We study the ground state of a bilayer system of dipolar bosons with dipoles oriented by an external field perpendicularly to the two parallel planes. By decreasing the interlayer…
