Organic Superconductors

These materials show a wide range of novel physical effects due to the strong interactions between the conduction electrons. These phenomena are unconventional superconductivity, the Mott transition, spin liquids, unconventional metals, and valence bond solid. In COPE we work on both the theory of these materials as well as synthesising them and measuring their properites.

Is a superconductor nearly a spin liquid insulator? (Ben Powell)

Imagine that we are having a dinner party. We have decided to seat our guests around a table so that each person has a member of the opposite sex on either side of them. If I have a square table and four guests this is not difficult. However, if we have a triangular table and three guests it is impossible. In an antiferromagnet the electrons want to sit with their spins pointing in the opposite direction to their neighbours. Again this is straightforward to arrange on a square lattice but impossible to achieve on the triangular lattice. This effect is known as frustration.
