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…
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…
Observation of Effective Pseudospin Scattering in ZrSiS
Michael S. Lodge, Guoqing Chang, Cheng-Yi Huang +10
3D Dirac semimetals are an emerging class of materials that possess topological electronic states with a Dirac dispersion in their bulk. In nodal-line Dirac semimetals, the conduct…
Large Fermi Arcs in Unconventional Weyl Semimetal RhSi
Guoqing Chang, Su-Yang Xu, Benjamin J. Wieder +8
The theoretical proposal of chiral fermions in topological semimetals has led to a significant effort towards their experimental realization. In particular, the Fermi surfaces of c…
A novel artificial condensed matter lattice and a new platform for one-dimensional topological phases
Ilya Belopolski, Su-Yang Xu, Nikesh Koirala +22
Engineered lattices in condensed matter physics, such as cold atom optical lattices or photonic crystals, can have fundamentally different properties from naturally-occurring elect…
