    • 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
      Accés obert
      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 ...

    • Three-dimensional hybrid vortex solitons 

      Driben, Rodislav; Kartashov, Yaroslav; Malomed, Boris A.; Meier, Torsten; Torner Sabata, Lluís (2014-06-16)
      Article
      Accés obert
      We show, by means of numerical and analytical methods, that media with a repulsive nonlinearity which grows from the center to the periphery support a remarkable variety of previously unknown complex stationary and dynamical ...

    • Twisted toroidal vortex solitons in inhomogeneous media with repulsive nonlinearity 

      Kartashov, Yaroslav V.; Malomed, Boris A.; Shnir, Yasha; Torner Sabata, Lluís (2014-12-24)
      Article
      Accés obert
      Toroidal modes in the form of so-called Hopfions, with two independent winding numbers, a hidden one (twist s), which characterizes a circular vortex thread embedded into a three-dimensional soliton, and the vorticity ...

    • Unbreakable PT symmetry of solitons supported by inhomogeneous defocusing nonlinearity 

      Kartashov, Yaroslav; Malomed, Boris A.; Torner Sabata, Lluís (OSA, 2014-09-24)
      Article
      Accés obert

    • Unbreakable PT symmetry of solitons supported by inhomogeneous defocusing nonlinearity 

      Kartashov, Yaroslav V.; Malomed, Boris A.; Torner Sabata, Lluís (2014-09-01)
      Article
      Accés restringit per política de l'editorial
      We consider bright solitons supported by a symmetric inhomogeneous defocusing nonlinearity growing rapidly enough toward the periphery of the medium, combined with an antisymmetric gain-loss profile. Despite the absence ...
