This article is a review of recent developments in the phenomenological description of
unconventional superconductivity. Starting with the BCS theory of superconductivity with …

Pairing symmetry in the cuprate superconductors is an important and controversial topic.
The recent development of phase-sensitive tests, combined with the refinement of several …

The Josephson effect describes supercurrent flowing through a junction connecting two
superconducting leads by a thin barrier. This current is driven by a superconducting phase …

Unconventional superconductivity (or superconductivity with a nontrivial Cooper pairing) is
believed to exist in many heavy-fermion materials as well as in high temperature …

An analytical formula for the dc Josephson current in anisotropic singlet superconductor/
insulator/anisotropic singlet superconductor junctions is presented. The formula is …

I review the principal theories that have been proposed for the superconducting phases of
UPt3. The detailed HT phase diagram places constraints on any theory for the multiple …

The formation of bound states at surfaces of materials with an energy gap in the bulk
electron spectrum is a well known physical phenomenon. At superconductor surfaces …

This colloquium reviews some unusual paramagnetic phenomena in granular high-
temperature superconductors. These are consistently explained by assuming that there is …

Abstract The dx 2− y 2-wave symmetry of the order parameter leads to various physical
phenomena of high-temperature superconductors which are not present in standard …

The traditional distinction between tunnel and highly transmissive barriers does not currently
hold for high critical temperature superconducting Josephson junctions, both because of …
