Spin-Chirality-Driven Bulk Photovoltaic Effect in van der Waals Magnet CrSBr
Dezhao Wu, Yong Xu, Meng Ye +1
The bulk photovoltaic effect (BPVE) can be greatly enriched in magnetic materials. Here, we establish vector spin chirality as a tunable knob for generating an unconventional time-…
Saturated and Anisotropic Magnetostriction in an Altermagnet
Zhiyuan Duan, Qiyun Xu, Peixin Qin +14
Magnetostriction, a fundamental phenomenon bridging magnetism and mechanics, has enabled a broad spectrum of applications. For almost two centuries, it has been mainly investigated…
Manipulating Charge Distribution in Moiré Superlattices by Light
Ruiping Guo, Haowei Chen, Wenhui Duan +2
In ordinary solids, nonlinear optical responses are typically studied in terms of unit-cell averages due to the angström-scale lattice constants. In contrast, moiré superlattices…
Multiple Layer-Selective Polar Charge Density Waves in
Wen-Han Dong, Wenhui Duan, Yong Xu +1
is a polar charge density wave (CDW) material, with giant thermal hysteresis and non-volatile state switching under electric and optical fields, attracting great…
ABACUS: An Electronic Structure Analysis Package for the AI Era
Weiqing Zhou, Daye Zheng, Qianrui Liu +55
ABACUS (Atomic-orbital Based Ab-initio Computation at USTC) is an open-source software for first-principles electronic structure calculations and molecular dynamics simulations. It…
Spin-chirality-driven second-harmonic generation in two-dimensional magnet CrSBr
Dezhao Wu, Yong Xu, Meng Ye +1
The interplay between magnetism and light can create abundant optical phenomena. Here, we demonstrate the emergence of an unconventional magnetization-induced second-harmonic gener…
