Vortex liquid crystals in anisotropic type II superconductors

, 2002
In a type II superconductor in a moderate magnetic field, the superconductor to normal state transition may be described as a phase transition in which the vortex lattice melts into a liquid. In a biaxial superconductor, or even a uniaxial superconductor

Gorkov equations for a pseudo-gapped high temperature superconductor

, 2000
A theory of superconductivity based on the two-body Cooperon propagator is presented. This theory takes the form of a modified Gorkov equation for the Green's function and allows one to model the effect of local superconducting correlations and long ...

Instabilities of High Temperature Superconductors [PDF]

Proceedings of the National Academy of Sciences, 1971
We have observed the transition temperature of both the cubic and tetragonal phases of several high-temperature β-W superconductors. The instability of the cubic lattice appears to be characteristic of high-temperature superconductors.

High-temperature superconductors

One of the main areas of focus in condensed matter physics over the past several years has been research on high-temperature superconductors and their physical characteristics. One of a metal’s most crucial characteristics is its electrical resistivity, and scientists were especially curious about how this value varied with temperature.
