Complex field-, temperature-, and angle-dependent Hall effects from intrinsic Fermi surface revealed by first-principles calculations
ShengNan Zhang, Zhihao Liu, Hanqi Pi +3
The Hall effect, ever intriguing since its discovery, has spurred the exploration of its phenomena, intensified by advances in topology and novel materials. Differentiating the ord…
Discovery of a metallic room-temperature d-wave altermagnet KV2Se2O
Bei Jiang, Mingzhe Hu, Jianli Bai +19
Beyond conventional ferromagnetism and antiferromagnetism, altermagnetism is a recently discovered unconventional magnetic phase characterized by time-reversal symmetry breaking an…
Bulk Photovoltaic Effects in Helimagnets
Chunmei Zhang, Jian Zhou
The bulk photovoltaic (BPV) effect that converts light into electric current is highly sensitive to the system symmetry and its electronic Bloch wavefunction. To create a sizable n…
First-principles methodology for studying magnetotransport in narrow-gap semiconductors: an application to Zirconium Pentatelluride ZrTe5
Hanqi Pi, Shengnan Zhang, Yang Xu +3
The origin of anomalous resistivity peak and accompanied sign reversal of Hall resistivity of ZrTe has been under debate for a long time. Although various theoretical models ha…
