Fig. 1: Double Rabi spiraling vortex.
From: Coupled quantum vortex kinematics and Berry curvature in real space
a, b Experimental amplitude and phase maps of the photonic emission from the polariton fluid, when exciting with a double vortex (lA = 2) and after arrival of a plain Gaussian pulse (lB = 0) at the time tAB = 2.04 ps. The different frames correspond to times t = 2.0, 2.32, 2.56, and 2.80 ps. The instantaneous phase singularities are tracked as yellow dots in the amplitude maps, and the solid lines represent the vortex trajectories drawn over two Rabi-oscillations periods (t = 2.0–3.6 ps, red and blue lines are used to distinguish the two different cores in the photon emission). c Vortex lines plotted as xyt curves (time range t = 0.5–10 ps, step δt = 0.02 ps).
