Observation of Weyl fermions in a magnetic non-centrosymmetric crystal
Daniel S. Sanchez, Guoqing Chang, Ilya Belopolski +15
Characterized by the absence of inversion symmetry, non-centrosymmetric materials are of great interest because they exhibit ferroelectricity, second harmonic generation, emergent…
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…
Discovery of Lorentz-violating Weyl fermion semimetal state in LaAlGe materials
Su-Yang Xu, Nasser Alidoust, Guoqing Chang +18
We report theoretical and experimental discovery of Lorentz-violating Weyl fermion semimetal type-II state in the LaAlGe class of materials. Previously type-II Weyl state was predi…
