High-temperature superconductivity in iron-based materials
The surprising discovery of high-temperature superconductivity in a material containing a strong magnet—iron—has led to thousands of publications. By placing all the data in context, it becomes clearExpand

Layer-by-layer entangled spin-orbital texture of the topological surface state in Bi2Se3.
We study Bi(2)Se(3) by polarization-dependent angle-resolved photoemission spectroscopy and density-functional theory slab calculations. We find that the surface state Dirac fermions areExpand

Strong surface scattering in ultrahigh mobility Bi2Se3 topological insulator crystals
havebeen studied. A comprehensive analysis of Shubnikov de Haas oscillations, Hall effect, and opticalreflectivity indicates that the measured electrical transport can be attributed solely to bulkExpand

Surface conduction of topological Dirac electrons in bulk insulating Bi2Se3
Despite their name, the bulk electrical conductivity of most topological insulators is relatively high, masking many of the important characteristics of its protected, surface conducting states.Expand

Field-induced quantum critical point in CeCoIn5.
The resistivity of the heavy-fermion superconductor CeCoIn5 was measured as a function of temperature, down to 25 mK and in magnetic fields of up to 16 T applied perpendicular to the basal plane.Expand

Link between spin fluctuations and electron pairing in copper oxide superconductors
Although it is generally accepted that superconductivity is unconventional in the high-transition-temperature copper oxides, the relative importance of phenomena such as spin and charge (stripe)Expand

Anisotropic Violation of the Wiedemann-Franz Law at a Quantum Critical Point
A quantum critical point transforms the behavior of electrons so strongly that new phases of matter can emerge. The interactions at play are known to fall outside the scope of the standard model ofExpand

Polarity-driven surface metallicity in SmB6.
By a combined angle-resolved photoemission spectroscopy and density functional theory study, we discover that the surface metallicity is polarity driven in SmB6. Two surface states, not accounted forExpand

Topological RPdBi half-Heusler semimetals: A new family of noncentrosymmetric magnetic superconductors
Tunable superconductivity and magnetism in noncentrosymmetric RPdBi provide a new route to exotic topological excitations. We report superconductivity and magnetism in a new family of topologicalExpand

Structural collapse and superconductivity in rare-earth-doped CaFe2As2
Aliovalent rare-earth substitution into the alkaline-earth site of CaFe${}_{2}$As${}_{2}$ single crystals is used to fine tune structural, magnetic, and electronic properties of this iron-basedExpand
