Parallel spin-momentum locking in a chiral topological semimetal
Jonas A. Krieger, Samuel Stolz, Inigo Robredo +23
Spin-momentum locking in solids describes a directional relationship between the electron's spin angular momentum and its linear momentum over the entire Fermi surface. While ortho…
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…
In situ modification of delafossite type PdCoO2 bulk single crystal for reversible hydrogen sorption and fast hydrogen evolution
Guowei Li, Seunghyun Khim, Celesta S. Chang +11
The observation of extraordinarily high conductivity in delafossite-type PdCoO2 is of great current interest, and there is some evidence that electrons behave like a fluid when flo…
Observation of giant spin-split Fermi-arc with maximal Chern number in the chiral topological semimetal PtGa
Mengyu Yao, Kaustuv Manna, Qun Yang +14
Non-symmorphic chiral topological crystals host exotic multifold fermions, and their associated Fermi arcs helically wrap around and expand throughout the Brillouin zone between th…
