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…
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…
