Topological Semimetals from first-principles
Heng Gao, Jörn W. F. Venderbos, Youngkuk Kim +1
We review recent theoretical progress in the understanding and prediction of novel topological semimetals. Topological semimetals define a class of gapless electronic phases exhibi…
Type-I and type-II Nodal Lines Coexistence in the Antiferromagnetic monolayer CrAs
Busheng Wang, Heng Gao, Qing Lu +5
Topological nodal line semimetals, hosting one-dimensional Fermi lines with symmetry protection, has become a hot topic in topological quantum matter. Due to the breaking of time r…
The Dirac-Weyl semimetal: Coexistence of Dirac and Weyl fermions in polar hexagonal crystals
Heng Gao, Youngkuk Kim, Jörn W. F. Venderbos +4
We propose that the noncentrosymmetric LiGaGe-type hexagonal crystal SrHgPb realizes a new type of topological semimetal that hosts both Dirac and Weyl points in momentum spa…
Spatially dispersive circular photogalvanic effect in a Weyl semimetal
Zhurun Ji, Gerui Liu, Zachariah Addison +8
Weyl semimetals are gapless topological states of matter with broken inversion and/or time reversal symmetry, which can support unconventional responses to externally applied elect…
