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…
Nearly-critical spin and charge fluctuations in KFe2As2 observed by high-pressure NMR
P. S. Wang, P. Zhou, J. Dai +7
We report a high-pressure 75As NMR study on the heavily hole-doped iron pnictide superconductor KFe2As2 (Tc~3.8 K). The low-energy spin fluctuations are found to decrease with appl…
Saddle point singularity and topological phase diagram in a tunable topological crystalline insulator (TCI)
Madhab Neupane, Su-Yang Xu, R. Sankar +15
A topological crystalline insulator (TCI) is a new phase of topological matter, which is predicted to exhibit distinct topological quantum phenomena, since space group symmetries r…
Minority-spin states and the degree of spin polarization in ferromagnetic metallic LaSrMnO ()
Z. Sun, Q. Wang, J. F. Douglas +10
Using angle-resolved photoemission spectroscopy (ARPES), we investigate the electronic band structure and Fermi surface of ferromagnetic LaSrMnO (…
A topological crystalline insulator (TCI) phase via topological phase transition and crystalline mirror symmetry
Su-Yang Xu, Chang Liu, Nasser Alidoust +18
A Z2 topological insulator protected by time-reversal symmetry is realized via spin-orbit interaction driven band inversion. For example, the topological phase in the Bi-Sb system…
Observation of Topological Crystalline Insulator phase in the lead tin chalcogenide Pb1-xSnxTe material class
Su-Yang Xu, Chang Liu, N. Alidoust +11
We perform systematic angle-resolved photoemission spectroscopic measurements on the lead tin telluride Pb1-xSnxTe pseudobinary alloy system. We show that the (001) crystalline sur…
