Signature of topological band crossing in ferromagnetic Cr1/3NbSe2 epitaxial thin film
Bruno Kenichi Saika, Satoshi Hamao, Yuki Majima +14
In intercalated transition metal dichalcogenides (I-TMDC), transition metal intercalation introduces magnetic phases which in some cases induce topological band crossing. However,…
downfolding based on the GW approximation for infinite-layer nickelates
Motoaki Hirayama, Yusuke Nomura, Ryotaro Arita
We derive an effective three-orbital model for the infinite-layer nickelates based on the band structure obtained by the GW approximation (GWA), where we consider the Ni 3$d_{x^2-y…
Anisotropic superconductivity in topological crystalline metal PbTaS with multiple Dirac fermions
Xiaohui Yang, Tonghua Yu, Chenchao Xu +10
Topological crystalline metals/semimetals (TCMs) have stimulated a great research interest, which broaden the classification of topological phases and provide a valuable platform t…
Emergence of spin-orbit coupled ferromagnetic surface state derived from Zak phase in a nonmagnetic insulator FeSi
Yusuke Ohtsuka, Naoya Kanazawa, Motoaki Hirayama +13
A chiral compound FeSi is a nonmagnetic narrow-gap insulator, exhibiting peculiar charge and spin dynamics beyond a simple band-structure picture. Those unusual features have been…
Absence of conventional room temperature superconductivity at high pressure in carbon doped HS
Tianchun Wang, Motoaki Hirayama, Takuya Nomoto +3
In this work, we show that the same theoretical tools that successfully explain other hydrides systems under pressure seem to be at odds with the recently claimed conventional room…
Multipole representation for anisotropic Coulomb interactions
Shoma Iimura, Motoaki Hirayama, Shintaro Hoshino
Multipole representation is proposed for the anisotropic Coulomb interactions in solids. Any local interactions can be expressed as the product of two multipole operators, and the…
