Observation of anomalous exciton polariton bands in PEPI perovskite based microcavity at room temperature
Chunzi Xing, Xiaokun Zhai, Chenxi Yang +9
Recently anomalous energy bands with negative mass attract intensive attention where non Hermiticity plays an important role. In this work we observe anomalous exciton polariton ba…
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…
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…
Exciton interaction induced spin splitting in MoS monolayer
Yao Li, G. Li, Xiaokun Zhai +11
By pumping nonresonantly a MoS monolayer at K under a circularly polarized cw laser, we observe exciton energy redshifts that break the degeneracy between B excitons with…
