Ultrafast μeV-Precision Bandgap Engineering in Low-Dimensional Topological Insulators
Peng Tan, Yuantao Chen, Yuqi Zhang +14
Precise and ultrafast control of electronic band structures is a central challenge for advancing quantum functional materials and devices. Conventional approaches--such as chemical…
Direct Raman observation of the quantum metric in a quantum magnet
Chao-Fan Wang, Han Ge, Jun-Yang Chen +4
The quantum geometric tensor (QGT) unifies the Berry curvature (its imaginary part) and the quantum metric (its real part), yet Raman studies of chiral phonons have so far accessed…
Magnetic order dependent photoluminescence from high energy excitons in hBN protected few-layer CrSBr
Xiaohua Wu, Junyang Chen, Mingqiang Gu +6
The detection and manipulation of the spin configurations in layered magnetic semiconductors hold significant interest for developing spintronic devices in two-dimensional limit. I…
Surprising pressure-induced magnetic transformations from Helimagnetic order to Antiferromagnetic state in NiI2
Qiye Liu, Wenjie Su, Yue Gu +9
Interlayer magnetic interactions play a pivotal role in determining the magnetic arrangement within van der Waals (vdW) magnets, and the remarkable tunability of these interactions…
