    • Effects of Fermion Exchange on the Polarization of Exciton Condensates 

      Combescot, Monique; Combescot, Roland; Alloing, Mathieu; Dubin, François (APS Physics, 2015-03-04)
      Article
      Accés obert
      Exchange interaction is responsible for the stability of elementary boson condensates with respect to momentum fragmentation. This remains true for composite bosons when single fermion exchanges are included but spin ...

    • Microscopic description of confined bosonic dipolar quantum gases in two dimensions 

      Sánchez Baena, Juan (Universitat Politècnica de Catalunya, 2015-06-21)
      Treball Final de Grau
      Accés obert
      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 ...

    • Mixtures of quantum dipolar gases: mixing and demixing 

      Pradas Rodriguez, Sergi (Universitat Politècnica de Catalunya, 2021-07-13)
      Treball Final de Grau
      Accés obert
      Presentem un anàlisis microscòpic de una barreja binaria de bosons dipolars a temperatura cero confinada en el pla xy amb moments dipolars (magnètics) permanents en la direcció z. Les interaccions dipol-dipol són repulsives ...

    • Vortex macroscopic superpositions in ultracold bosons in a double-well potential 

      Garcia-March, M. A.; Carr, Lincoln D. (2015-03-23)
      Article
      Accés obert
      We study macroscopic superpositions in the orbital rather than the spatial degrees of freedom, in a three-dimensional double-well system. We show that the ensuing dynamics of N interacting excited ultracold bosons, which ...
