    • Measuring Chern numbers in Hofstadter strips 

      Mugel, Samuel; Dauphin, Alexandre; Massignan, Pietro Alberto; Tarruell, Leticia; Lewenstein, Maciej; Lobo, Carlos; Celi, Alessio (2017-08-15)
      Article
      Open Access
      Topologically non-trivial Hamiltonians with periodic boundary conditions are characterized by strictly quantized invariants. Open questions and fundamental challenges concern their existence, and the possibility of measuring ...
    • Quantum liquid droplets in a mixture of Bose-Einstein condensates 

      Cabrera, C. R.; Tanzi, L.; Sanz, J.; Naylor, B.; Thomas, P.; Cheiney, P.; Tarruell, Leticia (2017)
      Article
      Open Access
      Quantum droplets are small clusters of atoms self-bound by the balance of attractive and repulsive forces. Here we report on the observation of a novel type of droplets, solely stabilized by contact interactions in a ...
    • Quantum liquid droplets in a mixture of Bose-Einstein condensates [Dataset] 

      Cabrera, C. R.; Tanzi, L.; Sanz, J.; Naylor, B.; Thomas, P.; Cheiney, P.; Tarruell, Leticia (Universitat Politècnica de Catalunya, 2017-08-25)

    • Three-dimensional droplets of swirling superfluids 

      Kartashov, Yaroslav V.; Malomed, Boris A.; Tarruell, Leticia; Torner Sabata, Lluís (American Physical Society (APS), 2018-07-12)
      Article
      Open Access
      A new method for the creation of 3D solitary topological modes, corresponding to vortical droplets of a two-component dilute superfluid, is presented. We use the recently introduced system of nonlinearly coupled Gross-Pitaevskii ...
