Topological Weyl phase transition in MoWTe
Ilya Belopolski, Daniel S. Sanchez, Yukiaki Ishida +21
Topological phases of matter exhibit phase transitions between distinct topological classes. These phase transitions are exotic in that they do not fall within the traditional Ginz…
Discovery of a new type of topological Weyl fermion semimetal state in MoWTe
Ilya Belopolski, Daniel S. Sanchez, Yukiaki Ishida +23
The recent discovery of a Weyl semimetal in TaAs offers the first Weyl fermion observed in nature and dramatically broadens the classification of topological phases. However, in Ta…
Atomic-scale visualization of quasiparticle interference on a type-II Weyl semimetal surface
Hao Zheng, Guang Bian, Guoqing Chang +15
We combine quasiparticle interference simulation (theory) and atomic resolution scanning tunneling spectro-microscopy (experiment) to visualize the interference patterns on a type-…
Observation of the spin-polarized surface state in a noncentrosymmetric superconductor BiPd
Madhab Neupane, Nasser Alidoust, M. Mofazzel Hosen +17
Recently, noncentrosymmetric superconductor BiPd has attracted considerable research interest due to the possibility of hosting topological superconductivity. Here we report a syst…
A minimal, "hydrogen atom" version of an inversion-breaking Weyl semimetal
Ilya Belopolski, Peng Yu, Daniel S. Sanchez +15
The recent explosion of research interest in Weyl semimetals has led to many proposed Weyl semimetal candidates and a few experimental observations of a Weyl semimetal in real mate…
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…
