Fig. 5: Single shot of a pentagon of polariton condensates with one fractured condensate.

Pentagon condensate with a ∣m∣ = 1 vortex–antivortex pair. a Experimental real-space PL and b, c phase extracted from interferometry from a single instance of the condensate. Simulated steady-state vortex–antivortex wavefunction d real-space density, e, f phase and g Fourier-space density. c, f Zoomed-in regions of the dashed squares in b, e, respectively. h Phase difference between different condensates (black dots) in the polygon extracted from the black circles in b. i Line profiles extracted along the two dashed circles in c, f. Yellow and green markers correspond to azimuthal angle equal to zero. Experimental data are represented by the coloured disks and numerical simulation by the black-dotted curves. Image a is saturated at a lower limit of 0.04 to allow for better visibility of the fringes.
