Tel.: 403/329-2191 Fax: 403/329-2057 EMail: k.vos@uleth.ca Part of our understanding of these materials comes from theoretically modeling the materials. The model will change depending on what physics is determined to be important. From these models we can then predict how the material will behave for example when the temperature changes or an electrical current passes through it. These predictions can be compared to experimental data and allow us to determine which theoretical model is valid for a given material, revealing important information about the physics of the system. Hence, an important part of our research is to test the theoretical models that have been proposed to describe these materials. In addition, I am studying the anisotropies of the Copper Oxide based compounds, which will give an explanation of certain physical features that the isotropic models cannot explain. The anisotropic effects arise because the SCES are not perfectly symmetric. The inclusion of anisotropic effects in our models will allow us to explain some of the physical properties that change as a function of doping. Below are two figures of Copper Oxide based compounds. YBa2Cu3O7 is a high temperature superconductor that is highly anisotropic. La2CuO4 is an antiferromagnetic insulator with a Neel temperature of 325o K.
