Disorder effects on the origin of high-order harmonic generation in solids
We consider noninteracting electrons coupled to laser fields and study perturbatively the effects of the lattice potential involving disorder on the harmonic components of the electric current, which are sources of high-order harmonic generation (HHG). By using the Floquet-Keldysh Green functions, w...
