Discovery of a Weyl Semimetal in non-Centrosymmetric Compound TaAs
Lexian Yang, Zhongkai Liu, Yan Sun +13
Three-dimensional (3D) topological Weyl semimetals (TWSs) represent a novel state of quantum matter with unusual electronic structures that resemble both a "3D graphene" and a topo…
Spectroscopic determination of the atomic f-electron symmetry underlying hidden order in URuSi
L. Andrew Wray, Jonathan Denlinger, Shih-Wen Huang +5
The low temperature hidden order state of URuSi has long been a subject of intense speculation, and is thought to represent an as yet undetermined many-body quantum state n…
Characterization of collective ground states in single-layer NbSe2
Miguel M. Ugeda, Aaron J. Bradley, Yi Zhang +14
Layered transition metal dichalcogenides (TMDs) are ideal systems for exploring the effects of dimensionality on correlated electronic phases such as charge density wave (CDW) orde…
Experimental Observation of Incoherent-Coherent Crossover and Orbital Dependent Band Renormalization in Iron Chalcogenide Superconductors
Zhongkai Liu, Ming Yi, Yan Zhang +13
The level of electronic correlation has been one of the key questions in understanding the nature of superconductivity. Among the iron-based superconductors, the iron chalcogenide…
Bandwidth and Electron Correlation-Tuned Superconductivity in RbFe(SeS)
M. Yi, Meng Wang, A. F. Kemper +8
We present a systematic angle-resolved photoemission spectroscopy study of the substitution-dependence of the electronic structure of RbFe(SeS) (z = 0…
Probing the Role of Interlayer Coupling and Coulomb Interactions on Electronic Structure in Few-Layer MoSe2 Nanostructures
Aaron J. Bradley, Miguel M. Ugeda, Felipe H. da Jornada +11
Despite the weak nature of interlayer forces in transition metal dichalcogenide (TMD) materials, their properties are highly dependent on the number of layers in the few-layer two-…
