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…
General Construction and Topological Classification of All Magnetic and Non-Magnetic Flat Bands
Dumitru Călugăru, Aaron Chew, Luis Elcoro +3
Exotic phases of matter emerge from the interplay between strong electron interactions and non-trivial topology. Owing to their lack of dispersion at the single-particle level, sys…
Catalogue of Flat-Band Stoichiometric Materials
Nicolas Regnault, Yuanfeng Xu, Ming-Rui Li +11
Topological electronic flatten bands near or at the Fermi level are a promising avenue towards unconventional superconductivity and correlated insulating states. However, the relat…
Realization of the field-free Josephson Diode
Heng Wu, Yaojia Wang, Yuanfeng Xu +7
The superconducting analog to the semiconducting diode, the Josephson diode, has long been sought, with multiple avenues to realization proposed by theorists. Exhibiting magnetic-f…
