Revealing Quantum Geometry in Nonlinear Quantum Materials
Yiyang Jiang, Tobias Holder, Binghai Yan
Berry curvature-related topological phenomena have been a central topic in condensed matter physics. Yet, until recently other quantum geometric quantities such as the metric and c…
Electrical magnetochiral anisotropy and quantum metric in chiral conductors
Yiyang Jiang, Qinyan Yi, Binghai Yan
Electrical magnetochiral anisotropy (EMCA) refers to the chirality- and current-dependent nonlinear magnetoresistance in chiral conductors and is commonly interpreted in a semiclas…
Hybrid-order topology in unconventional magnets of Eu-based Zintl compounds with surface-dependent quantum geometry
Yufei Zhao, Yiyang Jiang, Hyeonhu Bae +4
The exploration of magnetic topological insulators is instrumental in exploring axion electrodynamics and intriguing transport phenomena, such as the quantum anomalous Hall effect.…
Three-dimensional higher-order saddle points induced flat bands in Co-based kagome metals
Hengxin Tan, Yiyang Jiang, Gregory T. McCandless +2
The saddle point (van Hove singularity) exhibits a divergent density of states in 2D systems, leading to fascinating phenomena like strong correlations and unconventional supercond…
