Vortex clusters in a stirred polariton condensate
Ivan Gnusov, Stella Harrison, Sergey Alyatkin +3
The response of superfluids to the external rotation, evidenced by emergence of quantised vortices, distinguishes them from conventional fluids. In this work, we demonstrate that t…

Polariton vortex Chern insulator
Stella L. Harrison, Anton Nalitov, Pavlos G. Lagoudakis +1
We propose a vortex Chern insulator, motivated by recent experimental demonstrations on programmable arrangements of cavity polariton vortices by [Alyatkin et al., ArXiv:2207.01850…

Synchronization in optically-trapped polariton Stuart-Landau networks
Stella L. Harrison, Helgi Sigurdsson, Pavlos G. Lagoudakis
We demonstrate tunable dissipative interactions between optically trapped exciton-polariton condensates. We apply annular shaped nonresonant optical beams to both generate and conf…
