The group theory of Raman effect in magnetic materials
Rui-Chun Xiao, Xue Liu, Yuxuan Jiang +5
Although Raman scattering in magnetic materials exhibits rich experimental phenomena, the symmetry constraints on Raman tensors have not been fully elucidated. In this work, we use…
Harnessing hidden quantum metric response in a 2D magnet via nonlocal photovoltaic effect
Yong Tan, Qian Hu, Rui-Chun Xiao +11
The quantum geometry of Bloch wavefunctions underpins a wealth of emergent phenomena in quantum materials. Its imaginary part, the Berry curvature, has long been recognized as a ke…
Topological enhancement of a PT-symmetric Su-Schrieffer-Heeger quantum battery
A-Long Zhou, Ya-Wen Xiao, Nuo Xu +5
We investigate a non-Hermitian quantum battery based on the Su-Schrieffer-Heeger (SSH) lattice, charged through a parity-time (PT)-symmetric protocol that alternates gain and loss…
Magnetoelastic Transport-Path Reconstruction and Giant Magnetotransport Responses in a Two-Dimensional Antiferromagnet
Liu Yang, Ming Li, Shui-Sen Zhang +8
Nonvolatile magnetotransport responses in a single magnetic material have generally not been expected to exhibit a large ON/OFF ratio, because they are usually tied to spin-orbit c…
Microwave Signature of the Emerging Abrikosov Lattice Above
Hang Zhou, Zhanghai Chen, A. A. Varlamov +2
The emergence of the Abrikosov lattice in the normal phase of type-II superconducting films when the magnetic field approaches the critical field from above was predicted…
Control of out-of-plane anti-damping spin torque with a canted ferromagnetic spin source
Xiaoxi Huang, Daniel A. Pharis, Hang Zhou +13
To achieve efficient anti-damping switching of nanoscale magnetic memories with perpendicular magnetic anisotropy using spin-orbit torque requires that the anti-damping spin-orbit…
