    • Asymmetric solitons and domain walls supported by inhomogeneous defocusing nonlinearity 

      Kartashov, Yaroslav V.; Lobanov, Valery E.; Malomed, Boris A.; Torner Sabata, Lluís (2013-12-01)
      Article
      Accés restringit per política de l'editorial
      We show that an inhomogeneous defocusing nonlinearity that grows toward the periphery in the positive and negative transverse directions at different rates can support strongly asymmetric fundamental and multipole bright ...

    • 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 ...
