Spin-Triplet Topological Excitonic Insulators in Two-dimensional Materials
Huaiyuan Yang, Jiaxi Zeng, Yuelin Shao +3
Quantum spin-hall insulator (QSHI) processes nontrivial topology. We notice that the electronic structures of some particular QSHIs are favorable for realization of excitonic insul…
Electron Doping of a Double Perovskite Flat-band System
Lun Jin, Nicodemos Varnava, Danrui Ni +5
Electronic structure calculations indicate that the Sr2FeSbO6 double perovskite has a flat-band set just above the Fermi level that includes contributions from ordinary sub-bands w…
Obstructed surface states as the origin of catalytic activity in inorganic heterogeneous catalysts
Guowei Li, Yuanfeng Xu, Zhida Song +8
The discovery of new catalysts that are efficient, sustainable, and low-cost is a major research endeavor for many industrial chemical processes. This requires an understanding and…
Three-Dimensional Real Space Invariants, Obstructed Atomic Insulators and A New Principle for Active Catalytic Sites
Yuanfeng Xu, Luis Elcoro, Guowei Li +7
Topologically trivial insulators come in two kinds: atomic, where the Wannier charge centers (WCCs) are localized on the atoms, and obstructed atomic, where the WCCs are located aw…
Filling-Enforced Obstructed Atomic Insulators
Yuanfeng Xu, Luis Elcoro, Zhi-Da Song +6
Topological band theory has achieved great success in the high-throughput search for topological band structures both in paramagnetic and magnetic crystal materials. However, a sig…
High-throughput calculations of magnetic topological materials
Yuanfeng Xu, Luis Elcoro, Zhida Song +6
The discoveries of intrinsically magnetic topological materials, including semimetals with a large anomalous Hall effect and axion insulators, have directed fundamental research in…
