Quantum Fluids of Light in 2D Artificial Reconfigurable Aperiodic Crystals with Tailored Coupling
Sergey Alyatkin, Kirill Sitnik, Valtýr Kári Daníelsson +4
Aperiodic crystals are the intermediates between strictly periodic crystalline matter and amorphous solids. The lack of translational symmetry combined with intrinsic long-range or…
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…
Quantum Vortex Formation in the "Rotating Bucket'' Experiment with Polariton Condensates
Ivan Gnusov, Stella Harrison, Sergey Alyatkin +4
The appearance of quantised vortices in the classical ``rotating bucket'' experiments of liquid helium and ultracold dilute gases provides the means for fundamental and comparative…
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…
Reservoir optics with exciton-polariton condensates
Y. Wang, H. Sigurdsson, J. D. Töpfer +1
We investigate an all-optical microscale planar lensing technique based on coherent fluids of semiconductor cavity exciton-polariton condensates. Our theoretical analysis underpins…
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…
