First-principles method justifying the Dieke diagram and beyond
Katsuhiro Suzuki, Takao Kotani, Kazunori Sato
We present a method to determine the model Hamiltonians to treat rare-earth multiplets in solids from the results of the quasiparticle self-consistent \textit{GW} (QSGW) method. We…
Effect of magnetocrystalline anisotropy on magnetocaloric properties of AlFeB compound
Hung Ba Tran, Hiroyoshi Momida, Yu-ichiro Matsushita +4
It is well known that the temperature dependence of the effective magnetocrystalline anisotropy energy obeys the power law of magnetization in the Callen-Callen theory.…
Low-temperature acanthite-like phase of CuS: A first-principles study on electronic and transport properties
Ho Ngoc Nam, Katsuhiro Suzuki, Tien Quang Nguyen +4
The mobility and disorder in the lattice of Cu atoms as liquid-like behavior is an important characteristic affecting the thermoelectric properties of CuS. In this study, usi…
Non-linear extension of the dynamical linear response of spins; extended Heisenberg model
Haruki Okumura, Kazunori Sato, Takao Kotani
We introduce a new extended Heisenberg model. The model contains the orbital-dependent spins together with the retarded effects of spin torque. The model is directly derived from t…
First-principles calculation of electronic density of states and Seebeck coefficient in transition-metal-doped Si-Ge alloys
Ryo Yamada, Akira Masago, Tetsuya Fukushima +3
High value and large Seebeck coefficient have been reported in the nanostructured Fe-doped Si-Ge alloys. In this work, the large Seebeck coefficient in Fe-doped Si-Ge systems…
Accurate energy bands calculated by the hybrid quasiparticle self-consistent GW method implemented in the ecalj package
Daiki Deguchi, Kazunori Sato, Hiori Kino +1
We have recently implemented a new version of the quasiparticle self-consistent GW (QSGW) method in the ecalj package released at http://github.com/tkotani/ecalj. Since the new ver…
