    • Berezinskii-Kosterlitz-Thouless transition in two-dimensional dipolar stripes 

      Bombín Escudero, Raul; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi (American Physical Society (APS), 2019-12-05)
      Article
      Open Access
      A two-dimensional quantum system of dipoles, with a polarization angle not perpendicular to the plane, shows a transition from a gas to a stripe phase. We have studied the thermal properties of these two phases using the ...
    • Dilute dipolar quantum droplets beyond the extended Gross-Pitaevskii equation 

      Bötcher, Fabian; Wenzel, Matthias; Schmidt, Jan-Niklas; Guo, Mingyang; Langen, Tim; Ferrier-Barbut, Igor; Pfau, Tilman; Bombín Escudero, Raul; Sánchez Baena, Juan; Boronat Medico, Jordi; Mazzanti Castrillejo, Fernando Pablo (American Physical Society, 2019-11-08)
      Article
      Open Access
      Dipolar quantum droplets are exotic quantum objects that are self-bound due to the subtle balance of attraction, repulsion, and quantum correlations. Here we present a systematic study of the critical atom number of these ...
    • Dipolar Bose Supersolid Stripes 

      Bombín Escudero, Raul; Boronat Medico, Jordi; Mazzanti Castrillejo, Fernando Pablo (2017-12-20)
      Article
      Open Access
      We study the superfluid properties of a system of fully polarized dipolar bosons moving in the XY plane. We focus on the general case where the polarization field forms an arbitrary angle a with respect to the Z axis, ...
    • Finite-range effects in the two-dimensional repulsive Fermi polaron 

      Bombín Escudero, Raul; Cikojevic, Viktor; Sánchez Baena, Juan; Boronat Medico, Jordi (American Physical Society, 2021-04-01)
      Article
      Open Access
      We study the repulsive Fermi polaron in a two-component, two-dimensional system of fermionic atoms inspired by the results of a recent experiment with 173Yb atoms [N. Darkwah Oppong et al., Phys. Rev. Lett. 122, 193604 ...
    • Reply to "comment on 'Berezinskii-Kosterlitz-Thouless transition in two-dimensional dipolar stripes' " 

      Bombín Escudero, Raul; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi (American Physical Society, 2020-10-19)
      Article
      Open Access
      This is a Reply to the Comment from F. Cinti and M. Boninsegni on our recent work on the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a two-dimensional dipolar system [Bombín, Mazzanti, and Boronat, Phys. Rev. ...
    • 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 ...
    • Two-dimensional repulsive Fermi polarons with short- A nd long-range interactions 

      Bombín Escudero, Raul; Comparin, Tommaso; Bertaina, Gianluca; Mazzanti Castrillejo, Fernando Pablo; Giorgini, Stefano; Boronat Medico, Jordi (American Physical Society (APS), 2019-08-09)
      Article
      Open Access
      We study the repulsive polaron problem in a two-component two-dimensional system of fermionic atoms. We use two different interaction models: a short-range (hard-disk) potential and a dipolar potential. In our approach, ...
    • Ultracold Bose and Fermi dipolar gases : a quantum Monte Carlo study 

      Bombín Escudero, Raul (Universitat Politècnica de Catalunya, 2019-12-13)
      Doctoral thesis
      Open Access
      The object of study of this thesis are dipolar systems in the quantum degenerate regime. In general, dealing with many-body systems and evaluating their properties requires to deal with the the Schrödinger equation. In the ...
