The multi-THz conductivity of VO2 recorded during a photoinduced insulator-metal transition directly reveals the femtosecond dynamics of V-V stretching modes and electronic correlations. We suggest a novel qualitative model for the nonthermal phase t

We directly trace the multi-THz conductivity of VO2 during an insulator-metal transition triggered by a 12-fs light pulse. The femtosecond dynamics of lattice and electronic degrees of freedom are spectrally discriminated. A coherent wave packet moti

The mid-infrared ultrafast response of VO2 thin films following 10 fs interband excitation is investigated as a function of sample temperature and laser fluence. The dynamics of the terahertz conductivity provides an insight into the microscopic deta
