Lifshitz transition and van Hove singularity in a Topological Dirac Semimetal
Su-Yang Xu, Chang Liu, I. Belopolski +20
A topological Dirac semimetal is a novel state of quantum matter which has recently attracted much attention as an apparent 3D version of graphene. In this paper, we report critica…
Observation of Fermi Arc Surface States in a Topological Metal: A New Type of 2D Electron Gas beyond Z2 Topological Insulators
Su-Yang Xu, Chang Liu, Satya K. Kushwaha +15
In a topological insulator, it is the electrons on the surface or edge that carry the signature of topology. Recently, a novel topological state has been proposed in metals or semi…
Observation of a bulk 3D Dirac multiplet, Lifshitz transition, and nestled spin states in Na3Bi
Su-Yang Xu, Chang Liu, S. K. Kushwaha +20
Symmetry or topology protected Dirac fermion states in two and three dimensions constitute novel quantum systems that exhibit exotic physical phenomena. However, none of the studie…
