Nonlinear Orbital and Spin Edelstein Effect in Centrosymmetric Metals
Insu Baek, Seungyun Han, Suik Cheon +1
Nonlinear spintronics combines nonlinear dynamics with spintronics, opening up new possibilities beyond linear responses. A recent theoretical work [Xiao et al., Phys. Rev. Lett. 1…
Nonreciprocal spin waves in a chiral antiferromagnet without the Dzyaloshinskii-Moriya interaction
Suik Cheon, Hyun-Woo Lee, Sang-Wook Cheong
Non-reciprocal spin wave can facilitate the realization of spin wave logic devices. It has been demonstrated that the non-reciprocity can emerge when an external magnetic field is…
Chiral anomaly in noncentrosymmetric systems induced by spin-orbit coupling
Suik Cheon, Gil Young Cho, Ki-Seok Kim +1
The chiral anomaly may be realized in condensed matter systems with pairs of Weyl points. Here we show that the chiral anomaly can be realized in diverse noncentrosymmetric systems…

An antiferromagnet is a promising material for spin-orbit torque generation. Earlier studies of the spin-orbit torque in an antiferromagnet are limited to collinear spin configurat…
Aharonov-Casher-induced electric quadrupole of charge-neutral particles
Hojun Lee, Youngjae Jeon, Suik Cheon +1
The paper demonstrates that charge‑neutral particles with magnetic moments acquire an electric quadrupole moment in solids via the Aharonov‑Casher effect, and calculates this effec…
Current-driven collective control of helical spin texture in van der Waals antiferromagnet
Kai-Xuan Zhang, Suik Cheon, Hyuncheol Kim +14
Electrical control of quantum magnetic states is essential in spintronic science. Initial studies on the ferromagnetic state control were extended to collinear antiferromagnets and…
