Outline of Final Research Achievements

The creation of topological states of light and matter was explored using new methodologies, specifically (a) by the rapid rotation of a condensate of microcavity exciton-polaritons, and (b) investigation of new methods to fabricate structured topological and non-Hermitian (control over gain and loss landscape) lattices of exciton-polaritons.
We have created the first experimental technique capable of rapid rotation of polaritons and determined the optimal conditions for realising a bosonic fractional quantum Hall effect. Driven rotation of a spontaneously formed polariton condensate has been experimentally measured, and we have verified theoretically the ability to inject large amounts of angular momentum, as well as the formation of dense vortex lattices. We have also established a new fabrication platform using proton-implantation of semiconductor microcavities, which is capable of creating structured topological and non-Hermitian lattices of polaritons.

Academic Significance and Societal Importance of the Research Achievements

The development of two original platforms for topological states of light in an integrated, non-linear environment moves us towards the realisation of fractional quantum Hall states of light and a robust, controllable source of anyons, enabling potential topological quantum computing applications.
