Nonlinear Processes in Condensed Matter Driven by Terahertz Fields
accelerate valence electrons into the conduction band, enhancing conductivity in semiconductors [1,2]. At even higher field strengths, tunneling can drive electrons directly from the valence to the conduction [...] Cavalleri, Nonlinear light–matter interaction at terahertz frequencies. Adv. Opt.
