First-principles calculation method for electron transport based on grid Lippmann-Schwinger equation
Yoshiyuki Egami, Shigeru Iwase, Shigeru Tsukamoto +2
We develop a first-principles electron-transport simulator based on the Lippmann--Schwinger (LS) equation within the framework of the real-space finite-difference scheme. In our fu…
First-principles transport calculation method based on real-space finite-difference nonequilibrium Green's function scheme
Tomoya Ono, Yoshiyuki Egami, Kikuji Hirose
We demonstrate an efficient nonequilibrium Green's function transport calculation procedure based on the real-space finite-difference method. The direct inversion of matrices for o…
Novel time-saving first-principles calculation method for electron-transport properties
Yoshiyuki Egami, Kikuji Hirose, Tomoya Ono
We present a time-saving simulator within the framework of the density functional theory to calculate the transport properties of electrons through nanostructures suspended between…
Biorthogonal linear-scaling approach for the transcorrelated method
Masashi Kojo, Kikuji Hirose
We develop a biorthogonal linear-scaling algorithm for a transcorrelated method based on the localized nature of transformed orbitals. The transcorrelated method, which employs a s…
First-principles calculation of electronic polarization of III-V nanotubes
Jun Otsuka, Tomoya Ono, Kikuji Hirose
A first-principles study of the electronic polarization of BN and AlN nanotubes and their graphitic sheets under an external electric field has been performed. We found that the po…
Path-Integral Renormalization Group Treatments for Many-Electron Systems with Long-Range Repulsive Interactions
Masashi Kojo, Kikuji Hirose
A practical algorithm for many-electron systems based on the path-integral renormalization group (PIRG) method is proposed in the real-space finite-difference (RSFD) approach. The…
