Abstract
We investigate the relativistic zero balance of the oscillator strength sum rule in a single-layer graphene. The full energy-dependent characteristics are studied by ultrafast THz spectroscopy to probe the low-energy quasi-free absorption oscillator in conjunction with ultrafast optical spectroscopy to investigate the high-energy oscillator near Fermi level.
