  • Topological dragging of solitons 

    Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2005-12)
    Article
    Accés restringit per política de l'editorial
    We put forward properties of solitons supported by optical lattices featuring topological dislocations and show that solitons experience attractive and repulsive forces around the dislocations. Suitable arrangements of ...
  • Topological light bullets supported by spatiotemporal gain 

    Lobanov, Valery E.; Borovkova, Olga V.; Kartashov, Yaroslav; Vysloukh, Victor A.; Torner Sabata, Lluís (2012-02-02)
    Article
    Accés restringit per política de l'editorial
    We reveal that the competition among diffraction, cubic nonlinearity, two-photon absorption, and gain localized in both space and time results in arrest of collapse, suppression of azimuthal modulation instabilities for ...
  • Two-dimensional cnoidal waves in Kerr--type saturable nonlinear media 

    Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2003-07)
    Article
    Accés restringit per política de l'editorial
    We report theoretically the existence, classification, and basic properties of families of stationary two-dimensional cnoidal-type waves in bulk Kerr-type saturable nonlinear media. The families of two-dimensional cnoidal-type ...
