Optical Absorption Study by Ab initio Downfolding Approach: Application to GaAs
Kazuma Nakamura, Yoshihide Yoshimoto, Ryotaro Arita +2
We examine whether essence and quantitative aspects of electronic excitation spectra are correctly captured by an effective low-energy model constructed from an {\em ab initio} dow…
First-principles Calculation of Effective Onsite Coulomb Interaction of 3d Transition Metals: Constrained Local Density Functional Approach with Maximally Localized Wannier Function
Kazuma Nakamura, Ryotaro Arita, Yoshihide Yoshimoto +1
We present a new ab initio method for calculating effective onsite Coulomb interactions of itinerant and strongly correlated electron systems. The method is based on constrained lo…
Local and Reversible Change of the Reconstruction on Ge(001) Surface between c(4x2) and p(2x2) by Scanning Tunneling Microscopy
Yasumasa Takagi, Yoshihide Yoshimoto, Kan Nakatsuji +1
The reconstruction on Ge(001) surface is locally and reversibly changed between c(4x2) and p(2x2) by controlling the bias voltage of a scanning tunneling microscope (STM) at 80K. I…
