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…
