Higher-order topological metasurface based on split-ring resonators with dipole-quadrupole couplings
Alina D. Rozenblit, Nikita A. Olekhno
Photonic higher-order topological insulators (HOTI) are characterized by a hierarchy of topologically-protected states with different dimensionalities, making them especially inter…
Higher-order topological states mediated by long-range coupling in -symmetric lattices
Nikita A. Olekhno, Alina D. Rozenblit, Valerii I. Kachin +5
Topological physics opens a door towards flexible routing and resilient localization of waves of various nature. Recently proposed higher-order topological insulators provide advan…
Topological edge states of interacting photon pairs emulated in a topolectrical circuit
Nikita A. Olekhno, Egor I. Kretov, Andrei A. Stepanenko +7
Topological physics opens up a plethora of exciting phenomena allowing to engineer disorder-robust unidirectional flows of light. Recent advances in topological protection of elect…
Two-dimensional plasmons in the random impedance network model of disordered thin-film nanocomposites
Nikita Olekhno, Yaroslav Beltukov
Random impedance networks are widely used as a model to describe plasmon resonances in disordered metal-dielectric nanocomposites. In order to study thin films, two-dimensional net…
