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…
Spinor-Induced Instability of Kinks, Holes and Quantum Droplets
Yaroslav V. Kartashov, V. M. Lashkin, Michele Modugno +1
We address the existence and stability of one-dimensional (1D) holes and kinks and two-dimensional (2D) vortex-holes nested in extended binary Bose mixtures, which emerge in the pr…
Chiral condensates in a polariton hexagonal ring
Xuekai Ma, Yaroslav V. Kartashov, Alexey Kavokin +1
We model generation of vortex modes in exciton-polariton condensates in semiconductor micropillars, arranged into a hexagonal ring molecule, in the presence of TE-TM splitting. Thi…

Yaroslav V. Kartashov, Boris A. Malomed, Lluis Torner
We predict that Lee-Huang-Yang effect makes it possible to create stable quantum droplets (QDs) in binary Bose-Einstein condensates with a hetero-symmetric or hetero-multipole stru…
Stable nonlinear modes sustained by gauge fields
Yaroslav V. Kartashov, Vladimir V. Konotop
We reveal the universal effect of gauge fields on the existence, evolution, and stability of solitons in the spinor multidimensional nonlinear Schrödinger equation. Focusing on the…

Xuekai Ma, Yaroslav V. Kartashov, Tingge Gao +2
We introduce the phenomenon of spiraling vortices in driven-dissipative (non-equilibrium) exciton-polariton condensates excited by a non-resonant pump beam. At suitable low pump in…
Multidimensional hybrid Bose-Einstein condensates stabilized by lower-dimensional spin-orbit coupling
Y. V. Kartashov, L. Torner, M. Modugno +3
We show that attractive spinor Bose-Einstein condensates under the action of spin-orbit coupling (SOC) and Zeeman splitting form self-sustained stable two- and three-dimensional (2…

Yaroslav V. Kartashov, Boris A. Malomed, Lluis Torner
We show that metastable ring-shaped clusters can be constructed from two-dimensional quantum droplets in systems described by the Gross-Pitaevskii equations augmented with Lee-Huan…
Stable multi-ring and rotating solitons in two-dimensional spin-orbit coupled Bose-Einstein condensates with a radially-periodic potential
Yaroslav V. Kartashov, Dmitry A. Zezyulin
We consider two-dimensional spin-orbit coupled atomic Bose-Einstein condensate in a radially-periodic potential. The system supports different types of stable self-sustained states…

Yaroslav V. Kartashov, Boris A. Malomed, Leticia Tarruell +1
A new method for the creation of 3D solitary topological modes, corresponding to vortical droplets of a two-component dilute superfluid, is presented. We use the recently introduce…

Yaroslav V. Kartashov, Vladimir V. Konotop, Dmitry A. Zezyulin +1
The dynamic localization of a two-level atom in a periodic potential under the action of spin-orbit coupling and a weak harmonically-varying linear force is studied. We consider op…

Yaroslav V. Kartashov, Vladimir V. Konotop, Dmitry A. Zezyulin +1
We address Bloch oscillations of a spin-orbit coupled atom in periodic potentials of two types: Optical and Zeeman lattices. We show that in optical lattices the spin-orbit couplin…

Yaroslav V. Kartashov, Vladimir V. Konotop, Dmitry A. Zezyulin
Spin-orbit (SO) coupling can be introduced in a Bose--Einstein condensate (BEC) as a gauge potential acting only in a localized spatial domain. Effect of such a SO "defect" can be…

It is shown that spin-orbit interaction leads to drastic changes in wave patterns generated by a flow of two-component Bose-Einstein condensate (BEC) past an obstacle. The combined…

Waves with different symmetries exist in two-component Bose-Einstein condensates (BECs) whose dynamics is described by a system of coupled Gross-Pitaevskii (GP) equations. A first…
Quasi-compactons and bistability in exciton-polariton condensates
Yaroslav V. Kartashov, Vladimir V. Konotop, Lluis Torner
We address stationary patterns in exciton-polariton condensates supported by a narrow external pump beam, and we discover that even in the absence of trapping potentials, such cond…
