This thesis discusses how high-harmonic generation can probe static and dynamical properties in two-dimensional materials with hexagonal symmetry. It demonstrates that the high-harmonic spectrum encodes fingerprints of electronic band structure and interband coupling, compares gapless and gapped graphene, studies defect effects in hexagonal boron nitride, and proposes a light-driven method for observing valley polarization in pristine graphene using tailored laser pulses.Read more
