Superconductivity is the ability of certain materials to conduct
electrical current with no resistance and extremely low losses.
High temperature superconductors, such as La2-xSrxCuOx (Tc=40K) and
YBa2Cu3O7-x (Tc=90K), were discovered in 1987 and have been
actively studied since. In spite of an intense, world-wide,
research effort during this time, a complete understanding of the
copper oxide (cuprate) materials is still lacking. Many fundamental
questions are unanswered, particularly the mechanism by which
high-Tc superconductivity occurs. More broadly, the cuprates are in
a class of solids with strong electron-electron interactions. An
understanding of such "strongly correlated" solids is perhaps the
major unsolved problem of condensed matter physics with over ten
thousand researchers working on this topic. High-Tc superconductors
also have significant potential for applications in technologies
ranging from electric power generation and transmission to digital
electronics. This ability to carry large amounts of current can be
applied to electric power devices such as motors and generators,
and to electricity transmission in power lines. For example,
superconductors can carry as much as 100 times the amount of
electricity of ordinary copper or aluminium wires of the same size.
Many universities, research institutes and companies are working to
develop high-Tc superconductivity applications and considerable
progress has been made. This volume brings together new
leading-edge research in the field.
