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…
Electrically tunable nonrigid moire exciton polariton supersolids at room temperature
Xiaokun Zhai, Junhui Cao Chunzi Xing, Xinmiao Yang +8
A supersolid is a macroscopic quantum state which sustains superfluid and crystallizing structure together after breaking the U(1) symmetry and translational symmetry. On the other…
Observation of condensed moire exciton polaritons in twisted photonic lattices at room temperature
Chunzi Xing, Yu Wang, Tobias Schneider +11
Moire lattices attract significant attention in double-layer graphene and TMD layer heterostructures as well as in photonic crystals due to the interesting exotic physics that emer…
Splitting spin-orbit coupled polariton vortex pairs in the non-Hermitian Rashba-Dresselhaus band at room temperature
Xiaokun Zhai, Ying Gao, Xuekai Ma +6
Spin orbit coupling gives rise to intriguing physical phenomena in bosonic condensates, such as formation of stripe phases and domains with vortex arrays. However, how the non-Herm…
Optically and remotely controlling localization of exciton polariton condensates in a potential lattice
Qiang Ai, Jan Wingenbach, Xinmiao Yang +6
Exciton polaritons are inherently tunable systems with adjustable potential landscape. In this work we show that exciton polariton condensates can be selectively localized in a fix…
