Ultrashort laser-driven dynamics of massless Dirac electrons generating valley polarization in graphene
We identify and describe how intense short light pulses couple to massless Dirac fermions in two-dimensional systems. The ensuing excitation dynamics exhibits unusual scaling with the wavelength of the light due the linear dispersion of the band structure and the fact that light coupling is efficien...
