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-…
AI-accelerated metallized -bonding screening for superconductor discovery
Zechen Tang, Wen-Han Dong, Baochun Wu +11
The computational discovery of phonon-mediated superconductors is hindered by the prohibitive cost of density functional perturbation theory (DFPT). Here, guided by the metallized…
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…
Exciton-roton mode in moiré fractional Chern insulators
Xiaoyang Shen, Zijian Zhou, Ruiping Guo +4
Moiré fractional Chern insulators (FCIs) are a novel class of quantum matter that realizes fractional quantum Hall (FQH) physics in zero magnetic field and provides a platform for…
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…
