Figure 1. Layout of the studied system.

(a) A superconducting stripe of width W with a central, time-dependent, pinning line of width comparable to the vortex size (ξ is the superconducting coherence length), and a 4-point probe applied dc current (with density J), and measured voltage (V, at contacts separated by distance L). A depletion region is simulated as sinusoidally oscillating local heating up to the critical temperature T_c and back to working temperature, with frequency ω (see Methods). (b) Possible experimental setup corresponding to (a), by using a laser light at the far field passing through a metallic mask to create time-dependent and spatially modulated depletion of the superconducting condensate.
