  • Gapped spectrum in pair-superfluid bosons 

    Astrakharchik, Grigori; Zillich, Robert E.; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi (2016-12-22)
    Article
    Open Access
    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 distance, for a fixed value of the strength ...
  • Self-bound Bose mixtures 

    Staudinger, Clemens; Mazzanti Castrillejo, Fernando Pablo; Zillich, Robert E. (American Physical Society (APS), 2018-08-31)
    Article
    Open Access
    Recent experiments confirmed that fluctuations beyond the mean-field approximation can lead to self-bound liquid droplets of ultradilute binary Bose mixtures. We proceed beyond the beyond-mean-field approximation and study ...
