a Temperature dependence of the resistance of [Nb(2.0 nm)/V(2.0 nm)/Ta(2.0 nm)]5 film. b Real part of the THz conductivity spectra, measured at 8.0 K and 1.6 K. c Real part of the THz conductivity spectra, measured at 1.6 K, 50 mT, and different IDC. The spectra are normalized by the normal-state spectrum measured at 8.0 K. d I-V curves under in-plane magnetic field of ± 50 mT, with and without THz irradiation.
