    • Correlations in spin-orbit coupled ultracold quantum gases 

      Sánchez Baena, Juan (Universitat Politècnica de Catalunya, 2020-12-14)
      Doctoral thesis
      Open Access
      The main goal of this thesis is the computation of ground state properties of quantum many-body systems under Spin Orbit coupling (SOC) interactions out of the ultradilute regime. We present two approaches to fulfill this ...
    • Diffusion Monte Carlo methods for spin-orbit-coupled ultracold Bose gases 

      Sánchez Baena, Juan; Boronat Medico, Jordi; Mazzanti Castrillejo, Fernando Pablo (American Physical Society (APS), 2018-11-27)
      Article
      Open Access
      We present two diffusion Monte Carlo (DMC) algorithms for systems of ultracold quantum gases featuring synthetic spin-orbit interactions. The first one is a spin-integrated DMC method which provides fixed-phase energy ...
    • 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 ...
    • Droplets of trapped quantum dipolar bosons 

      Macia Rey, Adrián; Sánchez Baena, Juan; Boronat Medico, Jordi; Mazzanti Castrillejo, Fernando Pablo (2016-11-10)
      Article
      Open Access
      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 a repulsive two-body potential, we find a ...
    • Few trapped quantum dipoles: quantum versus classical structures 

      Sánchez Baena, Juan; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi (2018-01-31)
      Article
      Open Access
      We analyze the ground state of a two-dimensional quantum system of a few strongly confined dipolar bosons. Dipoles arrange in different stable structures that depend on the tilting polarization angle and the anisotropy of ...
    • 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 ...
    • Microscopic description of confined bosonic dipolar quantum gases in two dimensions 

      Sánchez Baena, Juan (Universitat Politècnica de Catalunya, 2015-06-21)
      Bachelor thesis
      Open Access
      We present a microscopic description of the two dimensional quantum few body problem involving confined polarized bosons. Due to anisotropy of the dipolar interaction, the system presents an interesting behaviour in terms ...
    • Supersolid striped droplets in a Raman spin-orbit-coupled system 

      Sánchez Baena, Juan; Boronat Medico, Jordi; Mazzanti Castrillejo, Fernando Pablo (American Physical Society, 2020-11-09)
      Article
      Open Access
      We analyze the role played by quantum fluctuations on a Raman spin-orbit-coupled system in the stripe phase under attractive interspin interactions. We show that beyond-mean-field effects stabilize the collapse predicted ...
    • Supersolid stripes enhanced by correlations in a Raman spin-orbit-coupled system 

      Sánchez Baena, Juan; Boronat Medico, Jordi; Mazzanti Castrillejo, Fernando Pablo (American Physical Society (APS), 2020-04-01)
      Article
      Open Access
      A Bose gas under the effect of Raman spin-orbit coupling (SOC) is analyzed using the discrete spin T-moves diffusion Monte Carlo method. Upon computing the energy as well as the static structure factor and the superfluid ...
