  • Topological States in Partially-PT -Symmetric Azimuthal Potentials 

    Kartashov, Yaroslav V.; Konotop, Vladimir V.; Torner Sabata, Lluís (APS, 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 ...
  • Stabilization of spatiotemporal solitons in Kerr media by dispersive coupling 

    Kartashov, Yaroslav V.; Malomed, Boris A.; Konotop, Vladimir V.; Lobanov, Valery E.; Torner Sabata, Lluís (2015-03-15)
    Article
    Accés obert
    We introduce a mechanism to stabilize spatiotemporal solitons in Kerr nonlinear media, based on the dispersion of linear coupling between the field components forming the soliton states. Specifically, we consider solitons ...
  • Dynamic versus Anderson wave-packet localization 

    Borovkova, Olga V.; Lobanov, Valery E.; Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (APS Physics, 2015-06-18)
    Article
    Accés obert
    We address the interplay between two fundamentally different wavepacket localization mechanisms, namely resonant dynamic localization due to collapse of quasi-energy bands in periodic media and disorder-induced Anderson ...

  • Self-deflecting plasmonic lattice solitons and surface modes in chirped plasmonic arrays 

    Li, Chunyan; Cui, Ran; Ye, Fangwei; Kartashov, Yaroslav V; Torner Sabata, Lluís; Chen, Xianfeng (OSA, 2015-03-04)
    Article
    Accés obert
    We show that chirped metal-dielectric waveguide arrays with focusing cubic nonlinearity can support plasmonic lattice solitons that undergo self-deflection in the transverse plane. Such lattice solitons are deeply ...
  • Nano Guiding of Light Using Dyakonov Waves 

    Takayama, Osamu; Artigas García, David; Torner Sabata, Lluís (OSA, 2014-12-01)
    Article
    Accés obert
  • Unbreakable PT symmetry of solitons supported by inhomogeneous defocusing nonlinearity 

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