Abstract
The class of high Tc superconductors share one common structural aspect, the existence
of planes of copper and oxygen ions. These planes are thought to be the source
of the superconducting behaviour. They can be represented as a two-dimensional
lattice of ions, which facilitates their study using numerical models. One such model
is the t − J model. In most studies utilising numerical models, the planes have been
considered isotropic. However, recent analysis of cuprate structure has illustrated
that this may not be representative of the copper oxide planes. A number of cuprate
structures exhibit different phases in which the planes are not isotropic, such as the
low temperature orthorhombic and low temperature tetragonal phases. This work
will examine the effects of introducing anisotropy into the t − J model in order to
understand how these phases affect the results gained from numerical studies.
