Hidden type-II Weyl points in the Weyl semimetal NbP
Shu-Chun Wu, Yan Sun, Claudia Felser +1
As one of Weyl semimetals discovered recently, NbP exhibits two groups of Weyl points with one group lying inside the plane and the other group staying away from this plane…
Electronic properties of topological insulator candidate CaAgAs
Jayita Nayak, Nitesh Kumar, Shu-Chun Wu +6
The topological phases of matter provide the opportunity to observe many exotic properties, like the existence of two dimensional topological surface states in the form of Dirac co…
A critical study of the elastic properties and stability of Heusler compounds: Cubic Co compounds with structure
Shu-Chun Wu, S. Shahab Naghavi, Gerhard H. Fecher +1
Elastic constants and their derived properties of various cubic Heusler compounds were calculated using first-principles density functional theory. To begin with, CuMnAl is use…
A critical study of the elastic properties and stability of Heusler compounds: Phase change and tetragonal compounds
Shu-Chun Wu, S. Shahab Naghavi, Gerhard H. Fecher +1
In the present work, the elastic constants and derived properties of tetragonal and cubic Heusler compounds were calculated using the high accuracy of the full-potential linearized…
Dirac dispersion generates large Nernst effect in Weyl semimetals
Sarah J. Watzman, Timothy M. McCormick, Chandra Shekhar +6
Weyl semimetals expand research on topologically protected transport by adding bulk Berry monopoles with linearly dispersing electronic states and topologically robust, gapless sur…
Stability of Weyl points in magnetic half-metallic Heusler compounds
S. Chadov, S. -C. Wu, C. Felser +1
We employ {\it ab-initio} fully-relativistic electronic structure calculations to study the stability of the Weyl points in the momentum space within the class of the half-metallic…
Dirac Line-nodes and Effect of Spin-orbit Coupling in Non-symmorphic Critical Semimetal MSiS (M=Hf, Zr)
C. Chen, X. Xu, J. Jiang +18
Topological Dirac semimetals (TDSs) represent a new state of quantum matter recently discovered that offers a platform for realizing many exotic physical phenomena. A TDS is charac…
