Finite-dimensional bistable topological insulators: From small to large
Weifeng Zhang, Xianfeng Chen, Yaroslav V. Kartashov +2
Photonic topological insulators supporting unidirectional topologically protected edge states represent attractive platform for realization of disorder- and backscattering-immune t…
Bloch oscillations of topological edge modes
Chunyan Li, Weifeng Zhang, Yaroslav V. Kartashov +2
Under the action of a weak constant force a wavepacket in periodic potential undergoes periodic oscillations in space, returning to the initial position after one oscillation cycle…
Bloch oscillations in arrays of helical waveguides
WeiFeng Zhang, Xiao Zhang, Yaroslav V. Kartashov +2
We study optical Bloch oscillations in the one- and two-dimensional arrays of helical waveguides with transverse refractive index gradient. Longitudinal rotation of waveguides may…
