    • Localization and delocalization of light in photonic moiré lattices 

      Wang, Peng; Zheng, Yuanlin; Chen, Xianfeng; Huang, Changming; Kartashov, Yaroslav V.; Torner Sabata, Lluís; Konotop, Vladimir V.; Ye, Fangwei (Macmillan Publishers, 2020-01-02)
      Article
      Open Access
      Moiré lattices consist of two superimposed identical periodic structures with a relative rotation angle. Moiré lattices have several applications in everyday life, including artistic design, the textile industry, architecture, ...
    • Localization-delocalization wavepacket transition in Pythagorean aperiodic potentials 

      Huang, Changming; Ye, Fangwei; Chen, Xianfeng; Kartashov, Yaroslav V.; Konotop, Vladimir V.; Torner, Lluis (Nature, 2016-09-02)
      Article
      Open Access
      We introduce a composite optical lattice created by two mutually rotated square patterns and allowing observation of continuous transformation between incommensurate and completely periodic structures upon variation of ...
    • Nonlinearity-induced photonic topological insulator 

      Maczewsky, Lukas J.; Heinrich, Matthias; Kremer, Mark; Ivanov, Seergey K.; Ehrhardt, Max; Martínez, Franklin; Kartashov, Yaroslav V.; Konotop, Vladimir V.; Torner Sabata, Lluís; Bauer, Dieter; Szameit, Alexander (2020-11-06)
      Article
      Open Access
      A hallmark feature of topological insulators is robust edge transport that is impervious to scattering at defects and lattice disorder. We demonstrate a topological system, using a photonic platform, in which the existence ...
    • 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
      Open Access
      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 ...

    • Topological States in Partially-PT -Symmetric Azimuthal Potentials 

      Kartashov, Yaroslav V.; Konotop, Vladimir V.; Torner Sabata, Lluís (APS, 2015-11-04)
      Article
      Open Access
      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 ...
