Layer Hall effect in a 2D topological Axion antiferromagnet
Anyuan Gao, Yu-Fei Liu, Chaowei Hu +33
While ferromagnets have been known and exploited for millennia, antiferromagnets (AFMs) were only discovered in the 1930s. The elusive nature indicates AFMs' unique properties: At…
Topology and geometry under the nonlinear electromagnetic spotlight
Qiong Ma, Adolfo G. Grushin, Kenneth S. Burch
For many materials, a precise knowledge of their dispersion spectra is insufficient to predict their ordered phases and physical responses. Instead, these materials are classified…
Deep-Learning-Enabled Fast Optical Identification and Characterization of Two-Dimensional Materials
Bingnan Han, Yuxuan Lin, Yafang Yang +22
Advanced microscopy and/or spectroscopy tools play indispensable role in nanoscience and nanotechnology research, as it provides rich information about the growth mechanism, chemic…
Purely rotational symmetry-protected topological crystalline insulator -Bi4Br4
Chuang-Han Hsu, Xiaoting Zhou, Qiong Ma +7
Recent theoretical advances have proposed a new class of topological crystalline insulator (TCI) phases protected by rotational symmetries. Distinct from topological insulators (TI…
Topological crystalline insulator states in the CaAs family
Xiaoting Zhou, Chuang-Han Hsu, Tay-Rong Chang +9
Topological crystalline insulators (TCI) are insulating electronic phases of matter with nontrivial topology originating from crystalline symmetries. Recent theoretical advances ha…
Direct optical detection of Weyl fermion chirality in a topological semimetal
Qiong Ma, Su-Yang Xu, Ching-Kit Chan +10
A Weyl semimetal (WSM) is a novel topological phase of matter, in which Weyl fermions (WFs) arise as pseudo-magnetic monopoles in its momentum space. The chirality of the WFs, give…
