Recently, the long-standing notion that the overdoped cuprate superconductors conform to a Landau-BCS description has been challenged strongly by new data on superfluid density and optical conductivity of high quality LSCO films. We show instead that a wide variety of experimental data on LSCO and Tl2201 (superfluid density, optics, heat capacity, thermal conductivity) can be explained by ...

The discovery of a superconducting phase in sulfur hydride under high pressure with a critical temperature above 200 K by Drozdov et al. [1] has provided a new impetus to the search for even higher Tc. The observation of a sharp drop in resistance to zero at Tc, its downward shift with magnetic field and a Meissner effect confirm superconductivity but the mechanism involved remains to be...

Unexplained to this day, the mysterious pseudogap phase of cuprate high-temperature superconductors is one of their key defining universal properties. Many scenarios have been proposed for its origin, but none has provided a satisfactory description so far. Part of the problem stems from the absence of a clear and sharp signature of the pseudogap at low temperatures in the vicinity of its...
