a, Conductance g versus gate voltage VG and parallel magnetic field B‖ at zero bias showing the 2e-to-1e peak splitting. b, Conductance versus source–drain voltage VSD and B‖, taken at VG = −14.92 V, showing a closing of the superconducting gap at Bc ≈ 640 mT, more than 500 mT after the onset of 1e periodicity.
