Insight Into

Much of the insight into the low temperature behaviour of two-dimensional quantum antiferromagnets has been recently obtained by extensive Monte Carlo. These models are relevant in the study of the magnetic behaviour of high Tc compounds containing copper-oxide layers. While of little technical importance, the physical properties of these models are certainly important for the understanding of the new type of behaviour that leads to superconductivity under certain conditions.

High Tc Superconductivity

The system X–La–Cu–O is described as a Fermi liquid with antiferromagnetic interaction. This interaction gives rise to two types of fluctuations, magnetic and superconducting. As a result, we find a free energy which contains two order parameters which at high temperature give rise to superconductivity and at low temperature to reentry-like paramagnetism. For two-dimensional systems, topological effects give rise to fractional statistics and as a result superconductivity appears when the topological angle θ gives rise to a Bose statistic.
