Fig. 6

a Vortex motion at different IDC in the time window around the peak of the THz pulse. The frequency is 0.3 THz and the peak amplitude of ITHz is 8 mA. The dashed line shows the Lorentz force exerted on the vortex. b Power exerted on the vortex at different IDC. For an easy view, the curve at the lowest DC current, IDC = 9 mA, is not shown. In addition, we do not plot the power after the vortex is deppined. c Plot indicating whether the vortex is pinned or depinned depending on IDC, under the influence of ITHz. The depinning region are filled with different colors, depending on at which cycle of the THz pulse the depinning occurs.
