Thouless Pumping of One-Dimensional Dark Solitons and Domain Walls
Fangwei Ye, Aidar H. Ryazhapov, Yaroslav V. Kartashov +1
We predict that quantized transport of dark solitons and domain walls can be observed in mutually sliding optical lattices in both focusing and defocusing nonlinear materials. Two…
Quantized transport of solitons in Bose-Einstein condensates driven by spin-orbit coupling
Yaroslav V. Kartashov, Vladimir V. Konotop, Dmitry A. Zezyulin
We demonstrate that linear and nonlinear Thouless pumping can be realized in two-component elongated Bose-Einstein condensates using helicoidal spin-orbit coupling that slides with…
Half-vortex soliton lattices in spin-orbit-coupled Bose-Einstein condensates with a quasi-flat band
Chenhui Wang, Yongping Zhang, Vladimir V. Konotop
Periodic potentials with flat bands in their spectra support strongly localized nonlinear excitations. Although a perfectly flat band cannot exist in a continuous system, a spin-or…
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…
Thouless pumping of solitons in a nonlocal medium
Fangwei Ye, Aidar H. Ryazhapov, Yaroslav V. Kartashov +1
Thouless pumping is a fundamental phenomenon recognized as being widespread across various areas of physics, with optics holding a particularly prominent role. Here, we study this…
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…
Transfer of solitons and half-vortex solitons via adiabatic passage
Chenhui Wang, Yongping Zhang, V. V. Konotop
We show that transfer of matter-wave solitons and half-vortex solitons in a spin-orbit coupled Bose-Einstein condensate between two (or more) arbitrarily chosen sites of an optical…
Dimers and discrete breathers in Bose-Einstein condensates in a quasi-periodic potential
Vladimir V. Konotop
A quasi-one-dimensional Bose-Einstein condensate loaded into a quasi-periodic potential created by two sub-lattices of comparable amplitudes and incommensurate periods is considere…
Two-dimensional flat-band solitons in superhoneycomb lattices
Shuang Shen, Yiqi Zhang, Yaroslav V. Kartashov +2
Flat-band periodic materials are characterized by a linear spectrum containing at least one band where the propagation constant remains nearly constant irrespective of the Bloch mo…
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…

Dynamical suppression of tunneling and spin switching of a spin-orbit-coupled atom in a double-well trap

We predict wide-band suppression of tunneling of spin-orbit-coupled atoms (or noninteracting Bose-Einstein condensate) in a double-well potential with periodically varying depths o…
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…
