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…
Large-area and high-quality 2D transition metal telluride
Jiadong Zhou, Fucai Liu, Junhao Lin +24
Atomically thin transitional metal ditellurides like WTe2 and MoTe2 have triggered tremendous research interests because of their intrinsic nontrivial band structure. They are also…
Quasiparticle interference on cubic perovskite oxide surfaces
Yoshinori Okada, Tay-Rong Chang, Guoqing Chang +7
We report the first observation of coherent surface states on cubic perovskite oxide SrVO3(001) thin films through spectroscopic imaging scanning tunneling microscopy. A direct lin…
Theoretical prediction of magnetic and noncentrosymmetric Weyl fermion semimetal states in the R-Al-X family of compounds (R=rare earth, Al=aluminium, X=Si, Ge)
Guoqing Chang, Bahadur Singh, Su-Yang Xu +18
Weyl semimetals are novel topological conductors that host Weyl fermions as emergent quasiparticles. While the Weyl fermions in high-energy physics are strictly defined as the mass…
Signatures of the Adler-Bell-Jackiw chiral anomaly in a Weyl Fermion semimetal
Chenglong Zhang, Su-Yang Xu, Ilya Belopolski +20
Weyl semimetals provide the realization of Weyl fermions in solid-state physics. Among all the physical phenomena that are enabled by Weyl semimetals, the chiral anomaly is the mos…
