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…
Epitaxial engineering of flat silver fluorides cuprate analogs
Adam Grzelak, Haibin Su, Xiaoping Yang +3
As-grown AgF2 has a remarkably similar electronic structure as insulating cuprates, but it is extremely electronegative, which makes it hard to handle and dope. Furthermore, buckli…
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…
Effect of Varying the TD-lc-DFTB Range-Separation Parameter on Charge and Energy Transfer in a Model Pentacene/Buckminsterfullerene Heterojunction
Ala Aldin M. H. M. Darghouth, Mark E. Casida, Xi Zhu +6
Density-functional tight binding (DFTB) has become a popular form of approximate density-functional theory (DFT) based upon a minimal valence basis set and neglect of all but two c…
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…
Terahertz conductivity of twisted bilayer graphene
Xingquan Zou, Jingzhi Shang, Jianing Leaw +11
Using terahertz time-domain spectroscopy, the real part of optical conductivity [] of twisted bilayer graphene was obtained at different temperatures (10 -- 300 K) in the…
