Theory of high Tc Superconductors
POC: Paul Von Allmen
A silicon valley startup company, Ambature LLC, fabricated and tested a material that arguably holds promises for room temperature superconductivity. The material system consists of conventional YBa2Cu3O7-δ material with a proprietary surface treatment. Ambature asked JPL to provide theoretical support that will improve the understanding of the experimental data and further improve the performance. In 2011, we have computed the bulk electronic structure of YBa2Cu3O7 and YBa2Cu3O6 using first principles methods. We have also started optimizing the positions of the surface atoms in preparation of the study of atomic adsorption processes. In a parallel effort, we are developing a mean-field theory to compute the superconducting properties of these materials.
