Collisions and interactions of solitons. a 3D plots of transmitted light intensity through solitons “3” and “4” vs. x, y coordinates before, during, and after collision; Δxpre < w/2; collision results in repulsion, Δxpost > Δxpre (U = 55.2 V, f = 800 Hz, T = 50 °C, d = 8.0 μm). b Post-collision separation Δxpost as a function of the impact factor Δxpre (U = 54.8 V, f = 400 Hz, T = 45 °C, d = 8.0 μm). c Time dependence of the y-coordinates of two colliding solitons, with Δxpre < w/2; U = 52.1 V, f = 450 Hz, T = 45 °C, d = 7.5 μm. d The same dependence for solitons with w/2 < Δxpre < w; the same experimental conditions as in c. The lines represent linear fitting used to calculate the velocities indicated in the figures
