Bloch-Landau-Zener Oscillations in Moiré Lattices
Sergey K. Ivanov, Yaroslav V. Kartashov, Vladimir V. Konotop
We develop a theory of two-dimensional Bloch-Landau-Zener (BLZ) oscillations of wavepackets in incommensurate moiré lattices under the influence of a weak linear gradient. Unlike p…
Topological pumping of light governed by Fibonacci numbers
Ruihan Peng, Kai Yang, Qidong Fu +5
Topological pumping refers to transfer of a physical quantity governed by the systemtopology, resulting in quantized amounts of the transferred quantities. It is a ubiqui-tous wave…
Topological pumping of multi-frequency solitons
Yaroslav V. Kartashov, Fangwei Ye, Vladimir V. Konotop
We report on the topological pumping of quadratic optical solitons, observed through their quantized transport in a dynamic optical potential. A distinctive feature of this system…
Observation of localization of light in photonic quasicrystals of diverse symmetries
Peng Wang, Qidong Fu, Vladimir V. Konotop +2
Quasicrystals are ubiquitous in nature. Beyond crystalline solids, they can be created as optically induced or technologically fabricated structures in photonic and phononic system…
Observation of Thouless pumping of light in quasiperiodic photonic crystals
Kai Yang, Qidong Fu, Henrique C. Prates +4
Topological transport is determined by global properties of physical media where it occurs and is characterized by quantized amounts of adiabatically transported quantities. Discov…
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…
Suppression and restoration of disorder-induced light localization mediated by PT-symmetry breaking
Yaroslav V. Kartashov, Chao Hang, Vladimir V. Konotop +3
We uncover that the breaking point of the PT-symmetry in optical waveguide arrays has a dramatic impact on light localization induced by the off-diagonal disorder. Specifically, wh…
