I will explain why the HH generation always involves an intricate interplay between polarization and electronic currents, often within multiple bands of semiconductors, and how electrons can produce a strong quantum interference [Nature 523, 572 (2015)] whenever nonperturbative transitions can mutually dipole couple three bands. This quantum effect produces even-ordered HHs as well as synchronizes the temporal HH emission only with either the positive (negative) crests of the driving field. These properties can be utilized to control polarization direction, temporal, and spectral HH combs, making THz crystallography possible [ Nature Phot. 11, 227 (2017)]. I will also show how HSB radiation reveals structural details of the colliding quasiparticles [ Nature 533, 225 (2016)] and characterizes strong Coulombic and valleytronic effects in monolayer transition metal dichalcogenides.
