Transport tuning of photonic topological edge states by optical cavities
Chang-Yin Ji, Gui-Bin Liu, Yongyou Zhang +2
Crystal-symmetry-protected photonic topological edge states (PTESs) based on air rods in conventional dielectric materials are designed as photonic topological waveguides (PTWs) co…
Topological magneto-optical effects and their quantization in noncoplanar antiferromagnets
Wanxiang Feng, Jan-Philipp Hanke, Xiaodong Zhou +4
Reflecting the fundamental interactions of polarized light with magnetic matter, magneto-optical effects are well known since more than a century. The emergence of these phenomena…
Cat's cradle-like Dirac semimetals in layer groups with multiple screw axes: Application to 2D Borophene and Borophane
Xiaotong Fan, Dashuai Ma, Botao Fu +2
Recently, the crystal symmetry-protected topological semimetals have aroused extensive interests, especially for the nonsymmorphic symmetry-protected one. We list the possible nonm…
Hourglass-like Nodal Net Semimetal in Ag2BiO3
Botao Fu, Dashuai Ma, Xiaotong Fan +2
Based on first-principles calculation and analysis of crystal symmetries, we propose a kind of hourglass-like nodal net (HNN) semimetal in centrosymmetric Ag2BiO3 that is construct…
Monolayer group-III monochalcogenides by oxygen functionalization: a promising class of two-dimensional topological insulators
Si Zhou, Cheng-Cheng Liu, Jijun Zhao +1
Monolayer group-III monochalcogenides (MX, M = Ga, In; X = S, Se, Te), an emerging category of two-dimensional (2D) semiconductors, hold great promise for electronics, optoelectron…
Influence of magnetic disorders on Quantum Anomalous Hall Effect in Magnetic Topological Insulator Films beyond the two-dimensional limit
Xing Yanxia, Cheung King Tai, Xu Fuming +3
Quantum anomalous Hall effect (QAHE) has been experimentally realized in magnetic topological insulator (MTI) thin films fabricated on magnetically doped (Bi,Sb)2Te3. In a MTI thin…
