Topological edge and corner states in coupled wave lattices in nonlinear polariton condensates
Tobias Schneider, Wenlong Gao, Thomas Zentgraf +2
Topological states have been widely investigated in different types of systems and lattices. In the present work, we report on topological edge states in double-wave (DW) chains, w…
Dynamics of phase defects trapped in optically imprinted orbits in dissipative binary polariton condensate
Jan Wingenbach, Matthias Pukrop, Stefan Schumacher +1
We study the dynamics of phase defects trapped in a finite optically imprinted ring lattice in binary polariton condensates, under the influence of the cross-interaction (CI) betwe…
Manipulating polariton condensates by Rashba-Dresselhaus coupling at room temperature
Yao Li, Xuekai Ma, Xiaokun Zhai +4
The spin-orbit coupling plays an important role in the spin Hall effect and the topological insulators. In addition, the spin-orbit coupled Bose-Einstein condensates show remarkabl…
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…
Spiraling vortices in exciton-polariton condensates
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…
Multistable circular currents of polariton condensates trapped in ring potentials
Franziska Barkhausen, Stefan Schumacher, Xuekai Ma
We demonstrate the formation and trapping of different stationary solutions, oscillatory solutions, and rotating solutions of a polariton condensate in a planar semiconductor micro…
