Giant electro-optic effect in chiral topological semimetal RhSi
Zhi Li, Yuewen Gao, Yu Gu +3
We studied the linear electro-optic effect of chiral topological semimetal RhSi which is characterized by high-fold chiral fermions separated in energy space. We identify that the…
Detection of quantum geometric tensor by nonlinear optical response
Zhi Li, Takami Tohyama, Toshiaki Iitaka +2
Quantum geometric tensor (QGT), including a symmetric real part defined as quantum metric and an antisymmetric part defined as Berry curvature, is essential for understanding many…
Nonlinear optical response from quantum kinetic equation
Zhi Li, Takami Tohyama, Toshiaki Iitaka +2
Motivated by the nonlinear Hall effect observed in topological semimetals, we studied the photocurrent by the quantum kinetic equation. We recovered the shift current and injection…
GdN thin-film: Chern Insulating State on Square Lattice
Zhi Li, Jinwoong Kim, Nicholas Kioussis +6
Using first-principles calculations, we predict a Chern insulating phase in thin films of the ferromagnetic semi-metal GdN. In contrast to previously proposed Chern insulator candi…
Spin Dynamics and Resonant Inelastic X-ray Scattering in Chromium with Commensurate Spin-Density Wave Order
Koudai Sugimoto, Zhi Li, Eiji Kaneshita +2
We theoretically investigate spin dynamics and -edge resonant inelastic X-ray scattering (RIXS) of Chromium with commensurate spin-density wave (SDW) order, based on a multi-b…
Pressure Induced Ferromagnetism in Cubic Perovskite SrFeO3 and BaFeO3
Zhi Li, Toshiaki Iitaka, Takami Tohyama
The spin order in cubic perovskite SrFeO3 and BaFeO3 under high pressure is studied by density functional theory (DFT) calculation with local spin density approximation plus Hubbar…
First Principles Calculation of Helical Spin Order in Iron Perovskite SrFeO3 and BaFeO3
Zhi Li, Robert Laskowski, Toshiaki Iitaka +1
Motivated by recent discovery of ferromagnetism in cubic perovskite BaFeO3 under small magnetic field, we investigate spin order in BaFeO3 and isostructual SrFeO3 by the first prin…
