Multipolar fluctuations from localized 4f electrons in CeRh2As2
Koki Numa, Eri Matsuda, Akimitsu Kirikoshi +1
The heavy-fermion superconductor CeRh2As2 exhibits a non-superconducting phase transition that precedes the emergence of superconductivity. The nature of the corresponding order pa…
Light-induced nonlinear Edelstein effect under ferroaxial ordering
Akimitsu Kirikoshi, Satoru Hayami
Ferroaxial ordering, a spontaneous rotational distortion of the atomic arrangement, brings about a cross-product-type spin-orbit coupling (SOC) manifested as an electric toroidal d…
From localized 4f electrons to anisotropic exchange interactions in ferromagnetic CeRh6Ge4
Shoichiro Itokazu, Akimitsu Kirikoshi, Harald O. Jeschke +1
CeRh6Ge4 is a cerium-based ferromagnetic material exhibiting a quantum critical behavior under pressure. We derive effective exchange interactions, using the framework of density f…
Finite- antiferrotoroidal and ferritoroidal order in a distorted kagome structure
Akimitsu Kirikoshi, Satoru Hayami
A highly geometrically frustrated lattice structure such as a distorted kagome (or quasikagome) structure enriches physical phenomena through coupling with the electronic structure…
