Directional planar antennae in polariton condensates
Denis Aristov, Stepan Baryshev, Julian D. Töpfer +2
We report on the realization of all-optical planar microlensing for exciton-polariton condensates in semiconductor microcavities. We utilize spatial light modulators to structure a…
Antiferromagnetic Ising model in a triangular vortex lattice of quantum fluids of light
Sergey Alyatkin, Carles Milián, Yaroslav V. Kartashov +4
Vortices are topologically distinctive objects appearing as phase twists in coherent fields of optical beams and Bose-Einstein condensates. Structured networks and artificial latti…
Spontaneous formation of time-periodic vortex cluster in nonlinear fluids of light
Kirill A. Sitnik, Sergey Alyatkin, Julian D. Töpfer +4
We demonstrate spontaneous formation of a nonlinear vortex cluster state in a microcavity exciton-polariton condensate with time-periodic sign flipping of its topological charges a…
Geometric frustration in polygons of polariton condensates creating vortices of varying topological charge
Tamsin Cookson, Kirill Kalinin, Helgi Sigurdsson +6
Vorticity is a key ingredient to a broad variety of fluid phenomena, and its quantised version is considered to be the hallmark of superfluidity. Circulating flows that correspond…
