Observation of Weyl fermions in a magnetic non-centrosymmetric crystal
Daniel S. Sanchez, Guoqing Chang, Ilya Belopolski +15
Characterized by the absence of inversion symmetry, non-centrosymmetric materials are of great interest because they exhibit ferroelectricity, second harmonic generation, emergent…
Mirror protected Dirac fermions on a Weyl semimetal NbP surface
Hao Zheng, Guoqing Chang, Shin-Ming Huang +15
The first Weyl semimetal was recently discovered in the NbP class of compounds. Although the topology of these novel materials has been identified, the surface properties are not y…
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…
Criteria for directly detecting topological Fermi arcs in Weyl semimetals
Ilya Belopolski, Su-Yang Xu, Daniel Sanchez +16
The recent discovery of the first Weyl semimetal in TaAs provides the first observation of a Weyl fermion in nature and demonstrates a novel type of anomalous surface state, the Fe…
Atomic Scale Visualization of Quantum Interference on a Weyl Semimetal Surface by Scanning Tunneling Microscopy/Spectroscopy
Hao Zheng, Su-Yang Xu, Guang Bian +19
Weyl semimetals may open a new era in condensed matter physics, materials science and nanotech after graphene and topological insulators. We report the first atomic scale view of t…
Exotic Superconducting Properties in Topological Nodal Semimetal PbTaSe
Cheng-Long Zhang, Zhujun Yuan, Guang Bian +4
We report the electronic properties of superconductivity in the topological nodal-line semimetal PbTaSe. Angle-resolved photoemission measurements accompanied by band calculati…
Observation of surface states derived from topological Fermi arcs in the Weyl semimetal NbP
Ilya Belopolski, Su-Yang Xu, Daniel Sanchez +16
The recent experimental discovery of a Weyl semimetal in TaAs provides the first observation of a Weyl fermion in nature and demonstrates a novel type of anomalous surface state ba…
Topological Phase Transition in Single Crystals of
Hong Lu, Xiao Zhang, Shuang Jia
Single crystals of were synthesized from high-temperature solutions and characterized in terms of their structural and electrical properties. Based on the…
Large Magnetoresistance over an Extended Temperature Regime in Monophosphides of Tantalum and Niobium
Chenglong Zhang, Cheng Guo, Hong Lu +5
We report extremely large magnetoresistance (MR) in an extended temperature regime from 1.5 K to 300 K in non-magnetic binary compounds TaP and NbP. TaP exhibits linear MR around $…
