  • Abstract
    Ultrabroadband THz spectroscopy directly monitors the femtosecond onset of conductivity during the photoinduced insulator-to-metal phase transition in vanadium dioxide. We observe coherent structural distortions via anharmonic phonon coupling and fluence-dependent self-trapping of excitons.
