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 …

Microcavities are semiconductor, metal, or dielectric structures providing optical confinement
in one, two or three dimensions. At the end of the 20th century, microcavities have attracted …

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 …

High-spatial-resolution magnetic imaging has driven important developments in fields
ranging from materials science to biology. However, to uncover finer details approaching the …

Singly quantized vortices have already been observed in many systems, including the
superfluid helium, Bose-Einstein condensates of dilute atomic gases, and condensates of …

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

In a modern viewpoint relativistic quantum field theory is an emergent phenomenon arising
in the low-energy corner of the physical fermionic vacuum–the medium, whose nature …

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 …
