The quest for unconventional high-Tc superconductivity is one of the most outstanding research fields in our group. Besides the long-sought cuprate oxides, in recent time our attention has also turned to iridium oxides, which are widely studied by the experimental groups at the LPS. These systems are believed to posses the ingredients to produce a high Tc superconducting mechanism and present novel topological strong spin-orbit interaction. This is also the case in systems where magnetic impurities are embedded in a conventional superconductor, which can give rise to an anomalous superconducting states, displaying unconventional p-wave pairing and topological edge states. This challenging problems are also studied within ad hoc theoretical methods (such as DMFT), developed within our group.
