Fig. 3: Single shot of a pentagon of polariton condensates with a singly charged vortex at the centre.
Pentagon condensate with a charge m = − 1 vortex. a Experimental real-space PL, b Fourier-space PL and c, d phase extracted from interferometry from a single instance of the condensate. Simulated steady state m = −1 vortex wavefunction e real-space density, f Fourier-space density, and g, h phase. d, h Zoomed-in regions of the dashed squares in c, g, respectively. i Phase difference between adjacent condensates (black dots) around the polygon extracted from the black circles in c. The red line is the expected phase difference of θi,i+1 = 2π/5. Green and blue dash-dotted lines mark the maximum deviation. j Line profile extracted along the black circle in d, h demonstrating a full 2π phase winding. Yellow dots correspond to azimuthal angle equal to zero. Experimental data are represented by the coloured disks and numerical simulation by the black-dotted curve.
