Total-energy-assisted Tight-binding Method Based on Density Functional Theory - Design Principles toward Transferability and Extrapolation
Takeo Fujiwara, Yoshiro Nohara, Susumu Yamamoto
The previously proposed tight-binding method derived from the total energy has been extended within the local density approximation (TE-TB method; J. Phys. Soc. Jpn. 87, 064802 (20…
Element-selective tracking ultrafast demagnetization process in Co/Pt multilayer thin films by the resonant magneto-optical Kerr effect
Kohei Yamamoto, Souliman El Moussaoui, Yasuyuki Hirata +8
We examined the photo-induced dynamics of ferromagnetic Co/Pt thin films demonstrating perpendicular magnetic anisotropy with element specificity using resonant polar magneto-optic…
Capturing ultrafast magnetic dynamics by time-resolved soft x-ray magnetic circular dichroism
Kou Takubo, Kohei Yamamoto, Yasuyuki Hirata +9
Experiments of time-resolved x-ray magnetic circular dichroism (Tr-XMCD) and resonant x-ray scattering at a beamline BL07LSU in SPring-8 with a time-resolution of under 50 ps are p…
Interface electronic structure at the topological insulator - ferrimagnetic insulator junction
Y. Kubota, K. Murata, J. Miyawaki +15
An interface electron state at the junction between a three-dimensional topological insulator (TI) film of Bi2Se3 and a ferrimagnetic insulator film of Y3Fe5O12 (YIG) was investiga…
Phonon-Dressed Two-Dimensional Carriers on the ZnO Surface
R. Yukawa, K. Ozawa, S. Yamamoto +8
Two-dimensional (2D) metallic states formed on the ZnO(100) surface by hydrogen adsorption have been investigated using angle-resolved photoelectron spectroscopy (ARPES).…
Efficient and Accurate Linear Algebraic Methods for Large-scale Electronic Structure Calculations with Non-orthogonal Atomic Orbitals
H. Teng, T. Fujiwara, T. Hoshi +3
The need for large-scale electronic structure calculations arises recently in the field of material physics and efficient and accurate algebraic methods for large simultaneous line…
