Optical detection and manipulation of spontaneous gyrotropic electronic order in a transition-metal dichalcogenide semimetal
Su-Yang Xu, Qiong Ma, Yang Gao +16
The observation of chirality is ubiquitous in nature. Contrary to intuition, the population of opposite chiralities is surprisingly asymmetric at fundamental levels. Examples range…
Realization of an intrinsic, ferromagnetic topological state in MnBi8Te13
Chaowei Hu, Lei Ding, Kyle N. Gordon +18
The interplay between topology and magnetism is essential for realizing novel topological states including the axion insulator, the magnetic Weyl semimetal, etc. An intrinsically f…
Topological photocurrent responses from chiral surface Fermi arcs
Guoqing Chang, Jiaxin Yin, Titus Neupert +10
The nonlinear optical responses from topological semimetals are crucial in both understanding the fundamental properties of quantum materials and designing next-generation light-se…
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…
Electronic Transport and quantum oscillation of Topological Semimetals
Jin Hu, Su-Yang Xu, Ni Ni +1
Three-dimensional (3D) topological semimetals represent a new class of topological matters. The study of this family of materials has been at the frontiers of condensed matter phys…
