    • Topological states in partially-PT-symmetric azimuthal potentials 

      Kartashov, Yaroslav V.; Konotop, Vladimir V; Torner Sabata, Lluís (2015-11-04)
      Article
      Accés obert
      We introduce partially-parity-time (pPT)-symmetric azimuthal potentials composed from individual PT-symmetric cells located on a ring, where two azimuthal directions are nonequivalent in a sense that in such potential ...

    • Vortex lattice solitons supported by localized gain 

      Kartashov, Yaroslav V.; Konotop, Vladimir V; Vysloukh, Victor A.; Torner Sabata, Lluís (2010-10-01)
      Article
      Accés restringit per política de l'editorial
      We show that localized gain supports the existence of dissipative vortex solitons in periodic Kerr media with strong two-photon absorption. Vortex solitons exist in both focusing and defocusing media, with their propagation ...
