TL;DR: In this paper, the authors propose and investigate the potential of polariton graphs as an efficient analogue simulator for finding the global minimum of the XY model by imprinting polariton condensate lattices of bespoke geometries.

TL;DR: The experimental observation of the nonlinear analogue of the optical spin Hall effect under highly nonresonant circularly polarized excitation of an exciton-polariton condensate in a GaAs/AlGaAs microcavity is reported.

TL;DR: In this paper, a strain compensated planar GaAs/AlAs0.98P0.02 microcavity with embedded InGaAs quantum wells having a reduced cross-hatch disorder was used to overcome the photonic disorder.

TL;DR: In this paper, the polarization dynamics of a spatially expanding polariton condensate under nonresonant linearly polarized optical excitation were studied and the formation of non-trivial spin textures in the form of a quadruplet polarization pattern both in the linear and circular Stokes parameters, and an octuplet in the diagonal Stokes parameter.

TL;DR: This work investigates the propagation and scattering of polaritons in a planar GaAs microcavity in the linear regime under resonant excitation and demonstrates that these features are observed for negligible nonlinearity and are, therefore, not sufficient to identify dark and half-dark solitons.
