Topological Codes from Space Groups: A Route beyond Translation Invariance
Chong-Yuan Xu, Ze-Chuan Liu, Yong Xu
Translation invariance underlies all algebraic constructions of topological codes with geometrical locality. It has remained an open question whether codes that generically break t…
AI-accelerated metallized -bonding screening for superconductor discovery
Zechen Tang, Wen-Han Dong, Baochun Wu +11
The computational discovery of phonon-mediated superconductors is hindered by the prohibitive cost of density functional perturbation theory (DFPT). Here, guided by the metallized…
Transfer learning electronic structure: millielectron volt accuracy for sub-million-atom moiré semiconductor
Ting Bao, Ning Mao, Wenhui Duan +3
The integration of density functional theory (DFT) with machine learning enables efficient \textit{ab initio} electronic structure calculations for ultra-large systems. In this wor…
Stable magic angle in twisted Kane-Mele materials
Cheng Xu, Yong Xu, Wenhui Duan +1
We propose that flat bands and van Hove singularities near the magic angle can be stabilized against angle disorder in the twisted Kane-Mele model. With continuum model and maximal…
