Topological Dirac States and Pairing Correlations in the Non-Centrosymmetric Superconductor PbTaSe2
Tay-Rong Chang, Peng-Jen Chen, Guang Bian +13
Superconductivity in topological band structures is a platform for many novel exotic quantum phenomena such as emergent supersymmetry. This potential nourishes the search for topol…
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…
Arc-tunable Weyl Fermion metallic state in MoWTe
Tay-Rong Chang, Su-Yang Xu, Guoqing Chang +13
Weyl semimetals may open a new era in condensed matter physics because they provide the first example of Weyl fermions, realize a new topological classification even though the sys…
Fermi arc topology and interconnectivity in Weyl fermion semimetals TaAs, TaP, NbAs, and NbP
Chi-Cheng Lee, Su-Yang Xu, Shin-Ming Huang +11
The family of binary compounds including TaAs, TaP, NbAs, and NbP was recently discovered as the first realization of Weyl semimetals. In order to develop a comprehensive descripti…
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.
Discovery of a Weyl Fermion semimetal state in NbAs
Su-Yang Xu, Nasser Alidoust, Ilya Belopolski +21
We report the discovery of Weyl semimetal NbAs featuring topological Fermi arc surface states.
