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.
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…
Direct optical detection of Weyl fermion chirality in a topological semimetal
Qiong Ma, Su-Yang Xu, Ching-Kit Chan +10
A Weyl semimetal (WSM) is a novel topological phase of matter, in which Weyl fermions (WFs) arise as pseudo-magnetic monopoles in its momentum space. The chirality of the WFs, give…
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…
