Further information: Superconductivity is the complete loss of electrical resistance of a material when it is cooled below a critical temperature. The discovery of high temperature superconductivity in copper based ceramic materials in 1986, provoked dreams of levitating trains, no longer requiring liquid helium cooling for instruments such as Magnetic Resonance Imaging in hospitals, and lossless electric power transport. While a levitating SCMaglev train in Japan is the fastest train the world, our dreams have not been fulfilled and high temperature superconductivity remains one of the biggest outstanding problems in condensed matter physics.
The magnetic properties of copper based high temperature superconductors are thought by many to be key to their superconductivity, making neutron scattering an ideal probe for understanding high temperature superconductivity. This talk will discuss our understanding of the cuprate superconductors, and how the problem of high temperature superconductivity has positively feed into the development of experimental techniques. In particular we will examine the possible roll of an electronic ordering phenomena known as charge-stripe order in high temperature superconductivity.
Talk begins at 6:30pm, refreshments from 6:00pm.
