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 …

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 …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

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 …

Since the first days of high-T c superconductivity, the materials science and the physics of
grain boundaries in superconducting compounds have developed into fascinating fields of …

Recent studies on high-T c superconductors have aroused new interest in tunnelling effects
in unconventional superconductors. Unlike in conventional s-wave superconductors, the d …

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

The first edition of this book provided an introduction to the many static and dynamic features
of magnetic flux structures in what are now called classical or low-temperature …

Hole-doped cuprate high temperature superconductors have ushered in the modern era of
high temperature superconductivity (HTS) and have continued to be at center stage in the …
