Supersolids are an exotic macroscopic quantum phase that exists in ultracold atomic gases and III-V semiconductors at cryogenic temperatures. We experimentally demonstrate exciton-polariton supersolids at room temperature.
Interacting topological bosonic systems exhibit fundamentally distinct behaviour to their fermionic counterparts. We report the first topological parametric oscillators based on a Dirac-vortex nano-electro-mechanical cavity.
Vortex strings are hypothetical topological defects in the geometry of spacetime in cosmology. We report the first experimental observations of vortex string chiral modes using a meta-material system.
We propose a new design of on-chip isolator using photonic spin-orbit interaction. This work is featured as cover article and selected by Optics & Photonics News (OPN), The optical Society's monthly news magazine, as one of the world's 30 most clearly communicated breakthroughs in optics in 2016.
