Topological photocurrent responses from chiral surface Fermi arcs
Guoqing Chang, Jiaxin Yin, Titus Neupert +10
The nonlinear optical responses from topological semimetals are crucial in both understanding the fundamental properties of quantum materials and designing next-generation light-se…
Discovery of topological chiral crystals with helicoid arc states
Daniel S. Sanchez, Ilya Belopolski, Tyler A. Cochran +19
The quantum behaviour of electrons in materials lays the foundation for modern electronic and information technology. Quantum materials with novel electronic and optical properties…
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…
Type-II Topological Dirac Semimetals: Theory and Materials Prediction (VAl3 family)
Tay-Rong Chang, Su-Yang Xu, Daniel S. Sanchez +13
The discoveries of Dirac and Weyl semimetal states in spin-orbit compounds led to the realizations of elementary particle analogs in table-top experiments. In this paper, we propos…
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…
Discovery of the topological surface state in a noncentrosymmetric superconductor BiPd
Madhab Neupane, Nasser Alidoust, Su-Yang Xu +9
Recently, noncentrosymmetric superconductor BiPd has attracted considerable research interest due to the possibility of being a topological superconductor. Here, we report a system…
