This review provides a theoretical basis for understanding the current-phase relation (CΦR)
for the stationary (dc) Josephson effect in various types of superconducting junctions. The …

This review presents recent developments in the understanding of how impurities influence
the electronic states in the bulk properties of superconductors. The focus is on …

Tunneling spectroscopy has played a central role in the experimental verification of the
microscopic theory of superconductivity in classical superconductors. Initial attempts to apply …

Recent studies of the electromagnetic response of high-T c superconductors using terahertz,
infrared, and optical spectroscopies are reviewed. In combination these experimental …

We present the full analysis of the normal state properties of the spin-fermion model near the
antiferromagnetic instability in two dimensions. The model describes low-energy fermions …

Underdoped high-Tc superconductors are frequently characterised by a temperature, T*,
below which the normal-state pseudogap opens. Two different “phase diagrams” based on …

One of the keys to the high-temperature superconductivity puzzle is the identification of the
energy scales associated with the emergence of a coherent condensate of superconducting …

A detailed phenomenology of low energy excitations is a crucial starting point for
microscopic understanding of complex materials, such as the cuprate high-temperature …

The superconducting gap—an energy scale tied to the superconducting phenomena—
opens on the Fermi surface at the superconducting transition temperature (T c) in …

A term first coined by Mott back in 1968 a “pseudogap” is the depletion of the electronic
density of states at the Fermi level, and pseudogaps have been observed in many systems …
