  • Liquid state of one-dimensional Bose mixtures: a quantum Monte Carlo study 

    Parisi, L.; Astrakharchik, Grigori; Giorgini, Stefano (American Institute of Physics (AIP), 2019-03-14)
    Article
    Open Access
    By using exact quantum Monte Carlo methods we calculate the ground-state properties of the liquid phase in one-dimensional Bose mixtures with contact interactions. We find that the liquid state can be formed if the ratio ...
  • Single-particle versus pair superfluidity in a bilayer system of dipolar bosons 

    Macia Rey, Adrián; Astrakharchik, Grigori; Mazzanti Castrillejo, Fernando Pablo; Giorgini, Stefano; Boronat Medico, Jordi (2014-10-21)
    Article
    Open Access
    We consider the ground state of a bilayer system of dipolar bosons, where dipoles are oriented by an external field in the direction perpendicular to the parallel planes. Quantum Monte Carlo methods are used to calculate ...
  • Spin dynamics and Andreev-Bashkin effect in mixtures of one-dimensional Bose gases 

    Parisi, L.; Astrakharchik, Grigori; Giorgini, Stefano (American Institute of Physics (AIP), 2018-07-11)
    Article
    Open Access
    We investigate the propagation of spin waves in two-component mixtures of one-dimensional Bose gases interacting through repulsive contact potentials. By using quantum Monte Carlo methods we calculate static ground-state ...
  • Two-dimensional mixture of dipolar fermions: Equation of state and magnetic phases 

    Comparin, Tommaso; Bombín Escudero, Raul; Holzmann, Markus; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi; Giorgini, Stefano (American Physical Society (APS), 2019-04-08)
    Article
    Open Access
    We study a two-component mixture of fermionic dipoles in two dimensions at zero temperature, interacting via a purely repulsive 1/r3 potential. This model can be realized with ultracold atoms or molecules when their dipole ...
