    • Soliton gyroscopes in media with spatially growing repulsive nonlinearity 

      Driben, Rodislav; Kartashov, Yaroslav; Malomed, Boris A.; Meier, Torsten; Torner Sabata, Lluís (2014-01-15)
      Article
      Accés obert
      We find that the recently introduced model of self-trapping supported by a spatially growing strength of a repulsive nonlinearity gives rise to robust vortex-soliton tori, i.e., three-dimensional vortex solitons, with ...

    • Three-dimensional hybrid vortex solitons 

      Driben, Rodislav; Kartashov, Yaroslav; Malomed, Boris A.; Meier, Torsten; Torner Sabata, Lluís (2014-06-16)

      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 ...
