This review focuses on the most important features of the 40 K superconductor MgB 2—the
weakly interacting multiple bands (the σ and π bands) and the distinct multiple …

An overview of the theory of the upper critical field in dirty two-gap superconductors, with a
particular emphasis on MgB2 is given. We focus here on the maximum Hc2 which may be …

Recently superconductivity was discovered in the Kagome metal AV3Sb5 (A= K, Rb, and
Cs), which has an ideal Kagome lattice of vanadium. These V-based superconductors also …

The recently discovered Fe-pnictide and chalcogenide superconductors display low-
temperature properties suggesting superconducting gap structures which appear to vary …

We report angle-resolved photoemission experiments resolving the distinct electronic
structure of the inequivalent top and bottom (001) surfaces of WT e 2. On both surfaces, we …

Low-temperature electrical and thermal transport, magnetic penetration depth, and heat
capacity measurements were performed on single crystals of the actinide superconductor …

There is strong experimental evidence that the superconductor Sr 2 RuO 4 has a chiral p-
wave order parameter. This symmetry does not require that the associated gap has nodes …

We report experimental evidence for the observation of the superconducting amplitude
mode, the so-called ''Higgs” mode, in the charge density wave superconductor 2 H-NbSe 2 …

Scanning tunneling microscopy and spectroscopy measurements in the superconducting
dichalcogenide 2H-NbS 2 show a peculiar superconducting density of states with two well …

The in-plane resistivity ρ and thermal conductivity κ of the FeAs-based superconductor KFe
2 As 2 single crystal were measured down to 50 mK. We observe non-Fermi-liquid behavior …
