Symmorphic and nonsymmorphic symmetries jointly-protected hourglass phonons
Baobing Zheng, Fangyang Zhan, Xiaozhi Wu +2
Hourglass dispersion is generally believed to be solely protected by nonsymmorphic symmetries, because these symmetries can introduce high-dimensional projective representations. H…
A Photoinduced Floquet Mixed-Weyl Semimetallic Phase in a Carbon Allotrope
Tingwei Deng, Baobing Zheng, Fangyang Zhan +3
The interplay between light and matter attracts tremendous interest for exploring novel topological quantum states and their phase transitions. Here we show by first-principles cal…
Intrinsic quantum anomalous Hall phase induced by proximity in germanene/CrGeTe van der Waals heterostructure
Ruiling Zou, Fangyang Zhan, Baobing Zheng +3
A van der Waals heterostructure combined with intrinsic magnetism and topological orders have recently paved attractive avenues to realize quantum anomalous Hall effects. In this w…
Symmetry-Protected Topological Triangular Weyl Complex
R. Wang, B. W. Xia, Z. J. Chen +3
Weyl points are often believed to appear in pairs with opposite chirality. In this work, we show by first-principles calculations and symmetry analysis that single Weyl phonons wit…
