Charge Density Waves and the Hidden Nesting of Purple Bronze KMoO
Lei Su, Chuang-Han Hsu, Hsin Lin +1
We introduce the first multiorbital effective tight-binding model to describe the effect of electron-electron interactions in this system. Upon fixing all the effective hopping par…
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…
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…
New fermions on the line in topological symmorphic metals
Guoqing Chang, Su-Yang Xu, Shin-Ming Huang +13
Topological metals and semimetals (TMs) have recently drawn significant interest. These materials give rise to condensed matter realizations of many important concepts in high-ener…
Chiral p-wave superconductivity in Sb(111) thin films close to Van Hove singularities
Jin-Qin Huang, Chuang-Han Hsu, Hsin Lin +2
We theoretically investigate the development of unconventional superconductivity in the Sb(111) thin film when its Fermi level is tuned to near type-II Van Hove singularities (VHS)…
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…
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…
Room-temperature magnetic topological semimetal state in half-metallic Heusler CoTiX (X=Si, Ge, or Sn)
Guoqing Chang, Su-Yang Xu, Hao Zheng +8
Topological semimetals (TSMs) including Weyl semimetals and nodal-line semimetals are expected to open the next frontier of condensed matter and materials science. Although the fir…
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…
