Pairing interaction appears at room temperature in traditional superconductors with a Cooper instability in the Fermi sea. Here, Maier et al.report that in the pseudogap phase of cuprate, where this instability is absent, superconductivity arises fro

We present detailed measurements of the temperature-dependent Raman spectra of optimally doped Ba_{0.6}K_{0.4}Fe_{2}As_{2} and analyze the low-temperature spectra based on local-density-approximation band-structure calculations and the subsequent est

Experimental studies of the endpoint of the superconducting dome for (Bi,Pb)2Sr2CuO6+δ (Bi2201) and La2−xSrxCuO4 (LSCO) have raised questions regarding the nature of the cuprate pairing mechanism. Motivated by these experiments, we examine the res

The nature and mechanism of superconductivity in the extremely electron-doped FeSe based superconductors continues to be a matter of debate. In these systems, the hole-like band has moved below the Fermi energy, and various spin-fluctuation theories

Quasi-particle interference (QPI) measurements have provided a powerful tool for determining the momentum dependence of the gap of unconventional superconductors. Here we examine the possibility of using such measurements to probe the frequency and m

It is notoriously difficult to make quantitative theoretical predictions of the superconducting transition temperature, Tc, either from first-principles or even from a knowledge of normal state properties. Ultimately, this reflects the fact that the

The superconducting (SC) and charge-density-wave (CDW) susceptibilities of the two dimensional Holstein model are computed using determinant quantum Monte Carlo (DQMC), and compared with results computed using the Migdal-Eliashberg (ME) approach. We

While both the hole and electron doped cuprates can exhibit ${d}_{{x}^{2}\ensuremath{-}{y}^{2}}$-wave superconductivity, the local distribution of the doped carriers is known to be significantly different with the doped holes going primarily on the O
