Abstract

Strong-field terahertz excitations in solids non-resonantly create carriers and drive currents in solids on an ultrafast timescale. The resulting combined polarization- and carrier-dynamics are the basis of high-harmonic generation (HHG). A simultaneous resonant optical excitation extends this concept to high-order sideband generation (HSG). Based on a quantum many-body theory of HHG and HSG in solids, we exemplarly demonstrate the spectral and time-resolved properties of solid-state HHG. They include Bloch oscillations and a novel quantum-interference of electrons. Furthermore, we show the capability of HSG to monitor electron-hole recollisions.
