Anomalous Crystallinity and Magnetism in Chemically Disordered Coherent Heterostructures
Saeed S. I. Almishal, Sai Venkata Gayathri Ayyagari, Aaron Pearre +9
High-entropy oxide (HEO) thin films uniquely superimpose exceptional chemical disorder with exceptional crystalline quality and coherence - an intersection we term anomalous crysta…
Large Anomalous and Topological Hall Effect and Nernst Effect in a Dirac Kagome Magnet Fe3Ge
Chunqiang Xu, Shuvankar Gupta, Hengxin Tan +9
The search for kagome magnets with unconventional magnetic and electronic properties has gained significant attention in recent years. We report the magnetic, electronic, and therm…
Reconstructing the wavefunction of magnetic topological insulators MnBi2Te4 and MnBi4Te7 using spin-resolved photoemission
Xue Han, Jason Qu, Hengxin Tan +7
Despite their importance for exotic quantum effects, the surface electronic structure of magnetic topological insulators MnBi2Te4 and MnBi4Te7 remains poorly understood. Using high…
Room temperature quantum metric effect in TbMn6Sn6
Weiyao Zhao, Kaijian Xing, Yufei Zhao +10
Quantum geometry, including Berry curvature and the quantum metric, of the electronic Bloch bands has been studied via nonlinear responses in topological materials. Naturally, thes…
Disordered charge density waves in the kagome metal FeGe
Hengxin Tan, Binghai Yan
The discovery of a charge density wave (CDW) in the antiferromagnetic kagome metal FeGe has prompted interest in the interplay between kagome physics, CDW, and magnetism. However,…
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…
Chiral charge density wave and backscattering-immune orbital texture in monolayer 1T-TiTe2
Mingqiang Ren, Fangjun Cheng, Yufei Zhao +7
Non-trivial electronic states are attracting intense attention in low-dimensional physics. Though chirality has been identified in charge states with a scalar order parameter, its…
Tuning the Intrinsic Spin Hall Effect by Charge Density Wave Order in Topological Kagome Metals
Diana Golovanova, Hengxin Tan, Tobias Holder +1
Kagome metals are topological materials with a rich phase diagram featuring various charge density wave orders and even unconventional superconductivity. However, little is still k…
