Picosecond current pulses directly drive depairing dynamics in superconductors.

Caption

A current pulse lasting only a few picoseconds passes through a superconductor before magnetic vortices have time to move. This lets the current reach far beyond the usual critical current, up to the point where Cooper pairs begin to break apart.
