The last decade witnessed significant progress in angle-resolved photoemission
spectroscopy (ARPES) and its applications. Today, ARPES experiments with 2-meV energy …

Theoretical ideas and experimental results concerning high-temperature superconductors
are reviewed. Special emphasis is given to calculations performed with the help of …

THE superconducting state of a metal is characterized by a complex order parameter with an
amplitude and a phase. In the BCS-Eliashberg mean-field theory1, which is a very good …

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 …

Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

Magnetic flux can penetrate a type-II superconductor in the form of Abrikosov vortices (also
called flux lines, flux tubes, or fluxons) each carrying a quantum of magnetic flux phi 0= h/2e …

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

A model of copper-oxygen bonding and antibonding bands with the most general two-body
interactions allowable by symmetry is considered. The model has a continuous transition as …

Superconducting gap anisotropy at least an order of magnitude larger than that of the
conventional superconductors has been observed in the ab plane of Bi 2 Sr 2 CaCu 2 O 8+ …

The authors present a review of recent muon spin rotation (μSR) studies of the vortex state in
type-II superconductors. There are significant gaps in our understanding of this unusual …
