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…
Experimental discovery of a topological Weyl semimetal state in TaP
Su-Yang Xu, Ilya Belopolski, Daniel S. Sanchez +24
Weyl semimetals are expected to open up new horizons in physics and materials science because they provide the first realization of Weyl fermions and exhibit protected Fermi arc su…
Unconventional transformation of spin Dirac phase across a topological quantum phase transition
Su-Yang Xu, Madhab Neupane, Ilya Belopolski +15
The topology of a topological material can be encoded in its surface states. These surface states can only be removed by a bulk topological quantum phase transition into a trivial…
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…
Discovery of a Weyl Fermion Semimetal and Topological Fermi Arcs
Su-Yang Xu, Ilya Belopolski, Nasser Alidoust +14
We report discovery of a Weyl Fermion semimetal and Topological Fermi arcs in TaAs
