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…
Helical polariton lasing from topological valleys in an organic crystalline microcavity
Teng Long, Xuekai Ma, Jiahuan Ren +6
Topological photonics provides an important platform for the development of photonic devices with robust disorder-immune light transport and controllable helicity. Mixing photons w…
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…
Tilting flat bands in an empty microcavity
Ying Gao, Yao Li, Xuekai Ma +4
Recently microcavities with anisotropic materials are shown to be able to create novel bands with non-zero local Berry curvature. The anisotropic refractive index of the cavity lay…
Realization of exciton-mediated optical spin-orbit interaction in organic microcrystalline resonators
Jiahuan Ren, Qing Liao, Xuekai Ma +3
The ability to control the spin-orbit interaction of light in optical microresonators is of fundamental importance for future photonics. Organic microcrystals, due to their giant o…
Switching off microcavity polariton condensate near the exceptional point
Yao Li, Xuekai Ma, Zaharias Hatzopoulos +3
Gain and loss modulation are ubiquitous in nature. An exceptional point arises when both the eigenvectors and eigenvalues coalesce, which in a physical system can be achieved by en…
