    • Andreev-Bashkin effect in superfluid cold gases mixtures 

      Nespolo, Jacopo; Astrakharchik, Grigori; Recati, Alessio (2017-12-05)
      Article
      Open Access
      © 2017 The Author(s). Published by IOP Publishing Ltd on behalf of Deutsche Physikalische Gesellschaft. We study a mixture of two superfluids with density-density and current-current (Andreev-Bashkin) interspecies interactions. ...
    • Coherent oscillations in small Fermi-polaron systems 

      Tylutki, Marek; Astrakharchik, Grigori; Recati, Alessio (AMER PHYSICAL SOC, 2017-12-01)
      Article
      Open Access
      We study the ground state and excitations of a one-dimensional trapped polarized Fermi gas interacting with a single impurity. First, we study the tunneling dynamics of the impurity through a potential barrier, such as one ...
    • Mass-driven vortex collisions in flat superfluids 

      Richaud, Andrea; Lamporesi, Giacomo; Capone, Massimo; Recati, Alessio (American Physical Society, 2023-05-26)
      Article
      Open Access
      Quantum vortices are often endowed with an effective inertial mass, due, for example, to massive particles in their cores. Such “massive vortices” display new phenomena beyond the standard picture of superfluid vortex ...
    • Repulsive Fermi polarons in a resonant mixture of ultracold 6Li atoms 

      Scazza, F; Valtolina, G; Massignan, Pietro Alberto; Recati, Alessio; Amico, A; Burchianti, A; Fort, C; Inguscio, M; Zaccanti, M; Roati, G (2017)
      Article
      Open Access
      We employ radio-frequency spectroscopy to investigate a polarized spin mixture of ultracold 6 Li atoms close to a broad Feshbach scattering resonance. Focusing on the regime of strong repulsive interactions, we observe ...
