Hidden chirality and half-vortex formation in exciton-polariton condensates
A. N. Osipov, I. Y. Chestnov, P. G. Lagoudakis +1
We show that a radially symmetric, nonresonantly pumped spinor exciton-polariton condensate can acquire chirality without a rotating drive, chiral geometry, or pump orbital angular…
Observation of an aperiodic polariton monotile
Sergey Alyatkin, Yaroslav V. Kartashov, Kirill Sitnik +2
A plethora of unconventional localization phenomena and fractal features of linear spectrum observed in quasiperiodic structures have been accompanied by a long-standing quest for…
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…
Polariton spin jets through optical control
Lucinda Pickup, Julian D. Töpfer, Helgi Sigurdsson +1
We demonstrate spin polarized jets in extended systems of ballistic exciton-polariton condensates in semiconductor microcavities using optical non-resonant excitation geometries. T…
Lotka-Volterra population dynamics in coherent and tunable oscillators of trapped polariton condensates
Julian D. Töpfer, Helgi Sigurdsson, Sergey Alyatkin +1
We demonstrate a regime in which matter-wave condensates of exciton-polaritons trapped in an elliptically shaped two-dimensional potential appear as a coherent mixture of ground an…
Quantum fluids of light in all-optical scatterer lattices
Sergey Alyatkin, Helgi Sigurdsson, Alexis Askitopoulos +2
One of the recently established paradigms in condensed matter physics is examining a system's behaviour in artificially constructed potentials, giving insight into physical phenome…
Plasmon enhanced optical tweezers with gold-coated black silicon
Domna G. Kotsifaki, Maria Kandyla, Pavlos G. Lagoudakis
Plasmonic optical tweezers are a ubiquitous tool for the precise manipulation of nanoparticles and biomolecules at low photon flux, while femtosecond-laser optical tweezers can pro…
