Halogen control of magnetic competition in Kitaev candidate Ru ( Cl, Br)

Ryuta Iwazaki, Shinnosuke Koyama, Takashi Koretsune +2

The authors derive effective pseudospin models from first‑principles Hubbard calculations for RuCl₃ and RuBr₃, showing that halogen substitution changes interlayer exchange and orb…

Flexocurrent-induced magnetization: Strain gradient-induced magnetization in time-reversal symmetric systems

Shinnosuke Koyama, Takashi Koretsune, Kazumasa Hattori

Symmetry constraints determine which physical responses are allowed in a given system. Magnetization induced by strain fields, such as in piezomagnetic and flexomagnetic effects, h…

First-principles analysis of in-plane anomalous Hall effect using symmetry-adapted Wannier Hamiltonians and multipole decomposition

Hiroto Saito, Takashi Koretsune

The in-plane anomalous Hall effect occurs when magnetization lies within the same plane as the electric field and Hall current, and requires magnetic point groups lacking rotationa…

Semi-automated estimation of hydrogenic initial states for localized Wannier functions

Tatsuki Oikawa, Kota Ido, Takahiro Misawa +2

We present a semi-automated method for obtaining an initial estimate of Wannier functions, designed to facilitate the construction of Wannier functions for describing low-energy ef…

DiracBilinears.jl: A package for computing Dirac bilinears in solids

Tatsuya Miki, Hsiao-Yi Chen, Takashi Koretsune +1

DiracBilinears.jl is a Julia package for computing Dirac bilinears, which are fundamental physical quantities of electrons in relativistic quantum theory, using first-principles ca…
