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…
Droplets of trapped quantum dipolar bosons
A. Macia, J. Sánchez-Baena, J. Boronat +1
Strongly interacting systems of dipolar bosons in three dimensions confined by harmonic traps are analyzed using the exact Path Integral Ground State Monte Carlo method. By adding…
