A strong-topological-metal material with multiple Dirac cones
Huiwen Ji, I Pletikosić, Q. D. Gibson +3
We report a new, cleavable, strong-topological-metal, Zr2Te2P, which has the same tetradymite-type crystal structure as the topological insulator Bi2Te2Se. Instead of being a semic…
Resonance-state-induced superconductivity at high Indium contents in In-doped SnTe
Neel Haldolaarachchige, Quinn Gibson, Weiwei Xie +3
We report a reinvestigation of superconducting SnInTe at both low and high In doping levels. Analysis of the superconductivity reveals a fundamental change as a funct…
Consequences of breaking time reversal symmetry in LaSb: a resistivity plateau and extreme magnetoresistance
F. F. Tafti, Q. D. Gibson, S. K. Kushwaha +2
Time reversal symmetry (TRS) protects the metallic surface modes of topological insulators (TIs). The transport signature of robust metallic surface modes of TIs is a plateau that…
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…
Time-Reversal Symmetry Breaking Type-II Weyl State in YbMnBi2
Sergey Borisenko, Daniil Evtushinsky, Quinn Gibson +6
Detection of Dirac, Majorana and Weyl fermions in real materials may significantly strengthen the bridge between high-energy and condensed-matter physics. While the presence of Dir…
Gapped Surface States in a Strong-Topological-Semimetal
A. P. Weber, Q. D. Gibson, Huiwen Ji +4
A three-dimensional strong-topological-insulator or -semimetal hosts topological surface states which are often said to be gapless so long as time-reversal symmetry is preserved. T…
