Unsupervised learning of non-Abelian multi-gap topological phases
Xiangxu He, Ruo-Yang Zhang, Xiaohan Cui +2
Recent experiments have successfully realized multi-band non-Abelian topological insulators with parity-time symmetry. Their topological classification transcends the conventional…
Band alignment effect in the topological photonic alloy
Tiantao Qu, Mudi Wang, Jun Chen +1
Recently, a photonic alloy with non-trivial topological properties has been proposed, based on the random mixing of Yttrium Iron Garnet (YIG) and magnetized YIG rods. When the dopi…
Electric field controlled valley-polarized photocurrent switch based on the circular bulk photovoltaic effect
Yaqing Yang, Xiaoyu Cheng, Liantuan Xiao +4
Efficient electric manipulation of valley degrees of freedom is critical and challenging for the advancement of valley-based information science and technology. We put forth an ele…
Topological photonic alloy
Tiantao Qu, Mudi Wang, Xiaoyu Cheng +6
We present the new concept of photonic alloy as a non-periodic topological material. By mixing non-magnetized and magnetized rods in a non-periodic 2D photonic crystal configuratio…
Gapless superconducting state and mirage gap in altermagnets
Miaomiao Wei, Longjun Xiang, Fuming Xu +3
The interplay between spin-orbit interaction (SOI) and magnetism produces interesting phenomena in superconductors. When a two-dimensional (2D) system with strong SOI is coupled to…
