Double-electron recombination in high-order-harmonic generation driven by spatially inhomogeneous fields
Original language description
We present theoretical studies of high-order harmonic generation (HHG) driven by plasmonic fields in two-electron atomic systems. Comparing the single-and two-electron active approximation models of the hydrogen negative ion, we provide strong evidence that a nonsequential double-electron recombination mechanism appears to be mainly responsible for the HHG cutoff extension. Our analysis is carried out by means of a reduced one-dimensional numerical integration of the two-electron time-dependent Schrodinger equation, and on investigations of the classical electron trajectories, resulting from the Newton's equation of motion.
