a, THz-MDCS spectra ENL(ωt, ωτ) at 16 K for pump electric field of 333 kV cm−1. b, Temporal profiles of two-pulse THz coherent signals ENL(t, τ) at various temperatures from 5 to 22 K for a peak THz pump electric field of Epump = 229 kV cm−1 and −τ = 6.5 ps. Traces are offset for clarity. c, Corresponding Fourier spectra of the coherent dynamics in b. d,e, A 2D false-colour plot of THz coherent signals as a function of temperature and frequency ωt (e) with the integrated spectral weight at various temperatures (d). The dashed grey line indicates the SC transition temperature.
