Ab-initio study of high harmonic generation from fullerenes: Multi-orbital effects, correlations, and size dependence

Km Akanksha Dubey, Ofer Neufeld

We study with ab-initio theory high harmonic generation (HHG) from a series of gas-phase fullerenes (from C${}_{20}$ to C${}_{60}$, including isomers) under varying laser conditions (l…
