    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 ...
  • 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 (OSA, 2015-03-11)
    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 ...
