Observation of Spin–Orbit Coupled Polariton Vortices at Room Temperature

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-Hermiticity affects the spatial distribution of spin-orbit coupled topological defects such as the vortex pair is still challenging to study. In the present work, we realize a nonequilibrium room-temperature exciton polariton condensate within a microdisk potential in a liquid crystal (LC) microcavity. We use the interplay
