A novel artificial condensed matter lattice and a new platform for one-dimensional topological phases
Ilya Belopolski, Su-Yang Xu, Nikesh Koirala +22
Engineered lattices in condensed matter physics, such as cold atom optical lattices or photonic crystals, can have fundamentally different properties from naturally-occurring elect…
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…
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…
Topological Nodal-Line Fermions in the Non-Centrosymmetric Superconductor Compound PbTaSe2
Guang Bian, Tay-Rong Chang, Raman Sankar +18
We report the identification of a Topological Nodal-Line Semimetal state in PbTaSe2.
Topological semimetals and topological insulators in rare earth monopnictides
Minggang Zeng, Chen Fang, Guoqing Chang +5
We use first principles calculations to study the electronic properties of rock salt rare earth monopnictides La (N, P, As, Sb, Bi). A new type of topological band crossing…
