Coupled anisotropic weak topological states and Floquet mixed-parity altermagnetism in two-dimensional Su-Schrieffer-Heeger models
Kunyuan Feng, Xibin Liu, Chenchen Liu +5
Su-Schrieffer-Heeger (SSH) topological systems and altermagnetic (AM) states are two important research areas in condensed matter physics. Realizing the coupled states between the…
New Group V Elemental Bilayers: A Tunable Structure Model with 4,6,8-atom Rings
Xiangru Kong, Linyang Li, Ortwin Leenaerts +2
Two-dimensional (2D) group V elemental materials have attracted widespread attention due to their nonzero band gap while displaying high electron mobility. Using first-principles c…
Carbon-Rich Carbon Nitride Monolayers with Dirac Cones: Dumbbell C4N
Linyang Li, Xiangru Kong, Ortwin Leenaerts +3
Two-dimensional (2D) carbon nitride materials play an important role in energy-harvesting, energy-storage and environmental applications. Recently, a new carbon nitride, 2D polyani…
Gallium Bismuth Halides GaBi-X2 (X= I, Br, Cl) Monolayers with Distorted Hexagonal Framework: Novel Room-Temperature Quantum Spin Hall Insulators
Linyang Li, Ortwin Leenaerts, Xiangru Kong +3
Quantum Spin Hall (QSH) insulators with a large topologically nontrivial bulk gap are crucial for future applications of the QSH effect. Among these, group III-V monolayers and the…
