Research Abstract

Time-resolved photoemission spectroscopy (TRPES) is the state-of-the-art spectroscopy technology which makes it possible to monitor the real-time change of the electronic structure (especially, near the Fermi level) under the optical excitation. It is a challenge not only in experiment but also in theory in a sense that its theoretical formulation is still lacking. Through developing our original formulation, we theoretically study TRPES in 1-imensional organic insulator, and graphite, quasi 2-dimensional gapless semiconductor. Novel microscopic understanding about the effects of ultrafast dynamics of electron and phonon on the underlying electronic structure could be made.
