Bound states in Bose-Einstein condensates with radially-periodic spin-orbit coupling
Chunyan Li, Vladimir V. Konotop, Boris A. Malomed +1
We consider Bose-Einstein condensate (BEC) subject to the action of spin-orbit-coupling (SOC) periodically modulated in the radial direction. In contrast to the commonly known prin…
Wannier solitons in spin-orbit-coupled Bose-Einstein condensates in optical lattices with a flat-band
Chenhui Wang, Yongping Zhang, V. V. Konotop
We investigate families of soliton solutions in a spin-orbit coupled Bose-Einstein condensate embedded in an optical lattice, which bifurcate from the nearly flat lowest band. Unli…
Vortex solitons in moire optical lattices
Sergey K. Ivanov, Vladimir V. Konotop, Yaroslav V. Kartashov +1
We show that optical moire lattices enable the existence of vortex solitons of different types in self-focusing Kerr media. We address the properties of such states both in lattice…
Observation of linear and nonlinear light localization at the edges of moiré lattices
A. A. Arkhipova, Y. V. Kartashov, S. K. Ivanov +11
We observe linear and nonlinear light localization at the edges and in the corners of truncated moiré lattices created by the superposition of periodic mutually-twisted at Pythagor…
