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…
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…
Controllable high-speed polariton waves in a PT-symmetric lattice
Xuekai Ma, Yaroslav Y. Kartashov, Tingge Gao +1
Parity-time (PT) symmetry gives rise to unusual phenomena in many physical systems, presently attracting a lot of attention. One essential and non-trivial task is the fabrication a…
Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation
E. Estrecho, T. Gao, N. Bobrovska +12
Bosonic condensates of exciton polaritons (light-matter quasiparticles in a semiconductor) provide a solid-state platform for studies of non-equilibrium quantum systems with a spon…
Controlled ordering of topological charges in an exciton-polariton chain
T. Gao, O. A. Egorov, E. Estrecho +6
We demonstrate, experimentally and theoretically, controlled loading of an exciton-polariton vortex chain into a 1D array of trapping potentials. Switching between two types of vor…
Chiral modes at exceptional points in exciton-polariton quantum fluids
T. Gao, G. Li, E. Estrecho +10
We demonstrate generation of chiral modes -- vortex flows with fixed handedness in exciton-polariton quantum fluids. The chiral modes arise in the vicinity of exceptional points (n…
