A three-dimensional magnetic topological phase
Ilya Belopolski, Daniel S. Sanchez, Guoqing Chang +16
We use photoemission spectroscopy to discover the first topological magnet in three dimensions, the material CoMnGa.
Topological Hopf and chain link semimetal states and their application to Co2MnGa (Theory and Materials Prediction)
Guoqing Chang, Su-Yang Xu, Xiaoting Zhou +9
Topological semimetals can be classified by the connectivity and dimensionality of the band cross- ing in momentum space. The band crossings of a Dirac, Weyl, or an unconventional…
Mirror protected Dirac fermions on a Weyl semimetal NbP surface
Hao Zheng, Guoqing Chang, Shin-Ming Huang +15
The first Weyl semimetal was recently discovered in the NbP class of compounds. Although the topology of these novel materials has been identified, the surface properties are not y…
Topological superconductor in quasi-one-dimensional Tl2-xMo6Se6
Shin-Ming Huang, Chuang-Han Hsu, Su-Yang Xu +4
We propose that the quasi-one-dimensional molybdenum selenide compound Tl2-xMo6Se6 is a time-reversal-invariant topological superconductor induced by inter-sublattice pairing, even…
Ultraquantum magnetoresistance in Kramers Weyl semimetal candidate -Ag2Se
Cheng-Long Zhang, Frank Schindler, Haiwen Liu +14
The topological semimetal -Ag2Se features a Kramers Weyl node at the origin in momentum space and a quadruplet of spinless Weyl nodes, which are annihilated by spin-orbit coupli…
Topological surface electronic states in candidate nodal-line semimetal CaAgAs
Xiao-Bo Wang, Xiao-Ming Ma, Eve Emmanouilidou +10
We investigate systematically the bulk and surface electronic structure of the candidate nodal-line semimetal CaAgAs by angle resolved photoemission spectroscopy and density functi…
