    • Distinguishability, degeneracy, and correlations in three harmonically trapped bosons in one dimension 

      Garcia March, Miguel Angel; Julia Diaz, Bruno; Astrakharchik, Grigori; Boronat Medico, Jordi; Polls, A. (2014-12-01)
      Article
      Open Access
      We study a system of two bosons of one species and a third atom of a second species in a one-dimensional parabolic trap at zero temperature. We assume contact repulsive inter- and intraspecies interactions. By means of an ...
    • Quantum correlations and spatial localization in one-dimensional ultracold bosonic mixtures 

      Garcia March, Miguel Angel; Julia Diaz, Bruno; Astrakharchik, Grigori; Busch, Th; Boronat Medico, Jordi; Polls, A. (2014-10-07)
      Article
      Open Access
      We present the complete phase diagram for one-dimensional binary mixtures of bosonic ultracold atomic gases in a harmonic trap. We obtain exact results with direct numerical diagonalization for a small number of atoms, ...
    • Sharp crossover from composite fermionization to phase separation in microscopic mixtures of ultracold bosons 

      Garcia March, Miguel Angel; Julia Diaz, Bruno; Astrakharchik, Grigori; Busch, T; Boronat Medico, Jordi; Rios Polls, Artur (2013-12-03)
      Article
      Open Access
      We show that a two-component mixture of a few repulsively interacting ultracold atoms in a one-dimensional trap possesses very diverse quantum regimes and that the crossover between them can be induced by tuning the ...
    • Universal dimerized quantum droplets in a one-dimensional lattice 

      Morera Navarro, Iván; Astrakharchik, Grigori; Polls Martí, Artur; Julia Diaz, Bruno (American Institute of Physics (AIP), 2021-01-11)
      Article
      Open Access
      The ground-state properties of two-component bosonic mixtures in a one-dimensional optical lattice are studied both from few- and many-body perspectives. We rely directly on a microscopic Hamiltonian with attractive ...
