Microscopic Conversion of Structural Chirality into Electronic Chirality in Artificial Chiral Clusters
Tenchi Endo, Satoru Hayami
We investigate how structural chirality is converted into electronic chirality in a two-dimensional cluster model consisting of a triangular-lattice core and three rod-like extensi…
Shape dependence of Edelstein and magnetoelectric effects in the V-shaped model
Shuhei Kanda, Satoru Hayami
We theoretically investigate the shape dependence and microscopic mechanism of the magnetoelectric (ME) effect, including both nonmagnetic (Edelstein-type) and magnetic origins, in…
Revisiting magnetoelectric response in collinear antiferromagnetic zigzag chains: A downfolding approach beyond conventional low-energy models
Shuhei Kanda, Satoru Hayami
Magnetoelectric (ME) effects in antiferromagnets provide a fertile platform for exploring symmetry-driven cross-correlated responses. However, their microscopic origin remains elus…
Nonlinear nonreciprocal electronic conductivity driven by magnetic field gradients
Taisei Yamanaka, Yoshihiko Ihara, Satoru Hayami
We theoretically propose the emergence of nonlinear nonreciprocal conductivity in centrosymmetric paramagnetic systems when a spatially gradient magnetic field is externally applie…
