Ab Initio Prediction of Large Thermoelectric Effect in Distorted Heusler Alloy Ti-Fe-Sb Compound
Rifky Syariati, Athorn Vora-ud, Fumiyuki Ishii +1
The thermoelectric figure of merit of the Heusler alloy TiFeSb was investigated by first-principles calculations of lattice thermal conductivity. The electronic thermal con…
Thermoelectric effect in kagome lattice enhanced at van Hove singularities
Kaiki Shibata, Naoya Yamaguchi, Hikaru Sawahata +1
We have performed first-principles calculations using density functional theory on a kagome lattice model with a chiral spin state, as a representative example demonstrating signif…
First-principles calculation of anomalous Hall and Nernst conductivity by local Berry phase
Hikaru Sawahata, Naoya Yamaguchi, Susumu Minami +1
In this study, we implemented a finite-difference algorithm for computing anomalous Hall and Nernst conductivity. Based on the expression to evaluate the Berry curvature in an insu…
First-principles LCPAO Approach for Insulators under Finite Electric Field
Naoya Yamaguchi, Fumiyuki Ishii
We propose a linear-combination-of-pseudo-atomic-orbitals scheme for a finite electric field method based on the modern theory of polarization. We derive the matrix elements of the…
Highly persistent spin textures with giant tunable spin splitting in the two-dimensional germanium monochalcogenides
Moh. Adhib Ulil Absor, Yusuf Faisho, Muhammad Anshory +4
The ability to control the spin textures in semiconductors is a fundamental step toward novel spintronic devices, while seeking desirable materials exhibiting persistent spin textu…
Anomalous transport due to Weyl fermions in the chiral antiferromagnets Mn, = Sn, Ge
Taishi Chen, Takahiro Tomita, Susumu Minami +9
The recent discoveries of strikingly large zero-field Hall and Nernst effects in antiferromagnets Mn, ( = Sn, Ge) have brought the study of magnetic topological states to…
