    • Dynamics of a massive superfluid vortex in rk confining potentials 

      Richaud, Andrea; Massignan, Pietro Alberto; Penna, Vittorio; Fetter, Alexander L. (American Physical Society, 2022-12-13)
      Article
      Accés obert
      We study the motion of a superfluid vortex in condensates having different background density profiles, ranging from parabolic to uniform. The resulting effective point-vortex model for a generic power-law potential ¿rk ...

    • Massive superfluid vortices and vortex necklaces on a planar annulus 

      Caldara, Matteo; Richaud, Andrea; Capone, Massimo; Massignan, Pietro Alberto (2023-08-09)
      Article
      Accés obert
      We study a superfluid in a planar annulus hosting vortices with massive cores. An analytical point-vortex model shows that the massive vortices may perform radial oscillations on top of the usual uniform precession of their ...

    • Path Integral Monte Carlo and Bose-Einstein condensation in quantum fluids and solids 

      Rota, Riccardo (Universitat Politècnica de Catalunya, 2011-12-20)
      Tesi
      Accés obert
      Several microscopic theories point out that Bose-Einstein condensation (BEC), i.e., a macroscopic occupation of the lowest energy single particle state in many-boson systems, may appear also in quantum fluids and solids ...

    • Propagation of collective modes in non-overlapping dipolar Bose-Einstein condensates 

      Gallemí Camacho, Alberto (Universitat Politècnica de Catalunya, 2013-07-19)
      Projecte Final de Màster Oficial
      Accés obert
      [ANGLÈS] We have studied the propagation of different collective modes of excitation (dipolar, monopolar and quadrupolar) in double and triple-well configurations in dipolar Bose-Einstein Condensates, due to the long-range ...
