Gauge invariance and interpretation of interband and intraband processes in high-order harmonic generation from bulk solids
A theoretical model for high-order harmonic generation (HHG) in bulk solids is considered. Our approach treats laser-induced inter-and intraband currents on an equal footing. The sum of these currents is the source of the high-order harmonic radiation, and does not depend on the particular electroma...
