Screening nearest-neighbor interactions in networks of exciton-polariton condensates through spin orbit coupling
Denis Aristov, Helgi Sigurdsson, Pavlos G. Lagoudakis
We study the modification of the spatial coupling parameter between interacting ballistic exciton-polariton condensates in the presence of photonic spin orbit coupling appearing fr…
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…
Minor embedding with Stuart-Landau oscillator networks
Stella L. Harrison, Helgi Sigurdsson, Pavlos G. Lagoudakis
We theoretically implement a strategy from quantum computation architectures to simulate Stuart-Landau oscillator dynamics in all-to-all connected networks, also referred to as com…
Old experiments in new light: Young's double-slit and Stern-Gerlach experiments in liquid crystal microcavities
Mateusz Król, Katarzyna Rechcińska, Helgi Sigurdsson +10
Spin-orbit interactions which couple spin of a particle with its momentum degrees of freedom lie at the center of spintronic applications. Of special interest in semiconductor phys…
Machine learning of phase transitions in nonlinear polariton lattices
D. Zvyagintseva, H. Sigurdsson, V. K. Kozin +4
Polaritonic lattices offer a unique testbed for studying nonlinear driven-dissipative physics. They show qualitative changes of a steady state as a function of system parameters, w…
All-optical linear polarization engineering in single and coupled exciton-polariton condensates
I. Gnusov, H. Sigurdsson, J. Toepfer +3
We demonstrate all-optical linear polarization control of exciton-polariton condensates in anisotropic elliptical optical traps. The cavity inherent TE-TM splitting lifts the groun…
