We review the recent two topics of optical excitation and relaxation dynamics, newly unveiled by the time- and momentum-resolved photo-electron emission from the conduction band of GaAs. One is the real-time collective relaxation dynamics, resulting

We study conceptional problems of a photo-electron emission (PEE) process from a free exciton in insulating crystals. In this PEE process, only the electron constituting the exciton is suddenly emitted out of the crystal, while the hole constituting

We show experimental and theoretical evidence that BiTeI hosts a novel disordered metallic state named diffusive helical Fermi liquid (DHFL), characterized by a pair of concentric spin-chiral Fermi surfaces with negligible inter-valley scattering. Ke

We will clarify, from the theoretical viewpoint, how electron correlations affect the density of states (DOS) and the angle-resolved photoemission spectra (ARPES). The two-dimensional half-filled Hubbard model is employed as a prototype of the intera

Using the quantum Monte-Carlo method, we have theoretically studied the metal–insulator transition of the one-dimensional half-filled Hubbard model, and calculated the momentum-specified Lehmann spectra, as well as the total density of states (DOS)

We have theoretically studied various one-, two- and three-dimensional half-filled Hubbard models from weak correlation cases to strong ones, and calculated the Lehmann’s spectra of the momentum-specified one-electron Green’s functions, as well a

By using the quantum Monte-Carlo method, we calculated the Lehmann spectra of momentum-specified one-body Green's functions as well as the total density of states (DOS), for one-dimensional half-filled Hubbard systems with various correlation strengt
