  • Abstract
    By using the intense THz pump-THz probe spectroscopy, we observed the collective Higgs amplitude mode of the BCS order parameter in a nonadiabatically-excited superconducting Nb1-xTixN films. The result opens a new pathway for ultrafast optical coherent control of macroscopic quantum states.
