Thresholdless corner vortex solitons in fractal Sierpiński topological insulators
Yiqi Zhang, Alexander V. Kireev, Victor O. Kompanets +12
Quantized vortices are ubiquitous in physics, spanning superconductivity, astrophysics, superfluid condensed matter systems, and nonlinear optics. Yet embedding vorticity into topo…
Observation of nonlinear topological corner states originating from different spectral charges
Victor O. Kompanets, Suge Feng, Yiqi Zhang +11
Higher-order topological insulators (HOTIs) are unique topological materials supporting edge states with the dimensionality at least by two lower than the dimensionality of the und…
Observation of nonlinear fractal higher-order topological insulator
Victor O. Kompanets, Hua Zhong, Yiqi Zhang +9
Higher-order topological insulators (HOTIs) are unique materials hosting topologically protected states, whose dimensionality is at least by a factor of 2 lower than that of the bu…
Macroscopic Zeno effect in Su-Schrieffer-Heeger photonic topological insulator
S. K. Ivanov, S. A. Zhuravitskii, N. N. Skryabin +6
The quantum Zeno effect refers to slowing down of the decay of a quantum system that is affected by frequent measurements. Nowadays, the significance of this paradigm is extended f…
Observation of solitons in oscillating waveguide arrays
Antonina A. Arkhipova, Yiqi Zhang, Yaroslav V. Kartashov +8
Floquet systems with periodically varying in time parameters enable realization of unconventional topological phases that do not exist in static systems with constant parameters an…
Observation of rotation-induced light localization in waveguide arrays
Chunyan Li, Antonina A. Arkhipova, Yaroslav V. Kartashov +8
We study both, experimentally and theoretically, propagation of light in the fs-laser written rotating square waveguide arrays and present the first experimental evidence of light…
