    • Floquet edge multicolor solitons 

      Ivanov, Seergey K.; Kartashov, Yaroslav V.; Szameit, Alexander; Torner Sabata, Lluís; Konotop, Vladimir V. (John Wiley & sons, 2022-03)
      Article
      Open Access
      Topological insulators are unique physical structures that are insulators in their bulk, but support currents at their edges which can be unidirectional and topologically protected from scattering on disorder and ...

    • 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 ...

    • Multifrequency solitons in commensurate-incommensurate photonic moiré lattices 

      Kartashov, Yaroslav V.; Ye, Fangwei; Konotop, Vladimir V.; Torner Sabata, Lluís (American Institute of Physics (AIP), 2021-10-15)
      Article
      Open Access
      We predict that photonic moiré patterns created by two mutually twisted periodic sublattices in quadratic nonlinear media allow the formation of parametric solitons under conditions that are strongly impacted by the geometry ...

    • 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 ...

    • Observation of linear and nonlinear light localization at the edges of moiré arrays 

      Arkhipova, Antonina; Kartashov, Yaroslav V.; Ivanov, Sergey K.; Zhuravitskii, Sergey; Skryabin, Nikolay; Dyakonov, Ivan; Kalinkin, Aleksandr; Kulik, Sergei; Kompanets, Victor O.; Chekalin, Sergey; Ye, Fangwei; Konotop, Vladimir V.; Torner Sabata, Lluís; Zadkov, Victor N. (American Institute of Physics (AIP), 2023-02-21)
      Article
      Open Access
      We observe linear and nonlinear light localization at the edges and in the corners of truncated moiré arrays created by the superposition of periodic mutually twisted at Pythagorean angles square sublattices. Experimentally ...

    • 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 ...

      Ivanov, Seergey K.; Kartashov, Yaroslav V.; Heinrich, Matthias; Szameit, Alexander; Torner Sabata, Lluís; Konotop, Vladimir V. (American Physical Society, 2021-05-11)
      Article
      Open Access
      We theoretically introduce a type of topological dipole soliton propagating in a Floquet topological insulator based on a kagome array of helical waveguides. Such solitons bifurcate from two edge states belonging to different ...

      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 ...

    • Two-dimensional Thouless pumping of light in photonic moiré lattices 

      Wang, Peng; Fu, Qidong; Peng, Ruihan; Kartashov, Yaroslav V.; Torner Sabata, Lluís; Konotop, Vladimir V.; Ye, Fangwei (2022-11-08)
      Article
      Open Access
      Continuous and quantized transports are profoundly different. The latter is determined by the global rather than local properties of a system, it exhibits unique topological features, and its ubiquitous nature causes its ...
