Title: Direct look at ultrafast dynamics of charge, lattice and spin with THz spectroscopy

Abstract: Ultrafast terahertz spectroscopy allows one to observe the dynamics of charge, lattice and spin in solids on the most elementary timescale: in the regime ωτ 〜 1, where ω is the electromagnetic wave oscillation frequency, and τ is the characteristic timescale at which the effects like electron momentum scattering, lattice oscillation, and spin precession occur. In this presentation, after a brief introduction and overview of my group activities, we will review two recent case studies: ultrafast electron transport in graphene, and fundamental observation of spin-dependent Mott scattering in ferromagnetic metals.
