Ultra-robust topologically protected edge states in quasi-1D systems
Valerii Kachin, Juan Camilo López Carreño, Magdalena Stobińska
In recent years, the study of topologically non-trivial structures in one-dimensional models has been dominated by the Su--Schrieffer--Heeger model due to its simplicity in design…
Effects of electron-electron interactions in the Yu-Shiba-Rusinov lattice model
Valerii Kachin, Teemu Ojanen, Jose L. Lado +1
In two-dimensional superconductors, Yu-Shiba-Rusinov bound states, induced by the magnetic impurities, extend over long distances giving rise to a long-range hopping model supporti…
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…
Three-dimensional higher-order topological insulator protected by cubic symmetry
Valerii I. Kachin, Maxim A. Gorlach
Recently discovered photonic higher-order topological insulators enable unprecedented flexibility in the robust localization of light in structures of different dimensionality. Whi…
