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

Recent experiments indicate that a photostimulated graphite with a femtosecond laser pulse results in the formation of a stable domain with sp 3 like interlayer bonds. By means of the energy barrier minimization and molecular dynamics using the empir

Structural changes of graphite surfaces induced by femtosecond (fs) laser excitation at a fluence regime above 75 mJ/cm2 are reported. Direct imagings of excited surfaces by means of scanning tunneling microscopy have revealed that fs-excitations ind

The formation energies and geometries of intrinsic interstitial and vacancy point defects in graphite are calculated using density functional theory and the generalized gradient approximation with a semi-empirical van der Waals (vdW) correction for d

The traditional Tamm–Dancoff (TD) method is one of the standard procedures for solving the Schrodinger equation of fermion many-body systems. However, it meets a serious difficulty when an instability occurs in the symmetry-adapted ground state of

We propose two possible quantum microscopic mechanisms for intervalley transitions just at the Franck-Condon state in GaAs. The first is the simultaneously combined coulombic elastic transitions of two electrons,from the originally photo-excited $\Ga
