Hedgehog spin texture and competing orders associated with strains on the surface of a topological crystalline insulator
Cheng-Yi Huang, Hsin Lin, Yung Jui Wang +2
We have investigated spin reorientation phenomena and interaction driven effects under the presence of applied strains on the (001) surface of PbSn(Te, Se) topological…
Topological phase diagram and saddle point singularity in a tunable topological crystalline insulator
Madhab Neupane, Su-Yang Xu, R. Sankar +17
We report the evolution of the surface electronic structure and surface material properties of a topological crystalline insulator (TCI) Pb1-xSnxSe as a function of various materia…
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…
