Summary on Grant Application Form
The physics of many metallic oxides is dominated by complex many-body effects which are at the boundary of our current understanding. An exciting possibility is that in some circumstances, they also drive a breakdown of Landau's Fermi Liquid Theory (FLT), which has been a cornerstone of our understanding of metal physics for forty years. If the 'Standard Model' of metals needs to be extended, it is likely that the next generation model will also lead to an improved understanding of the rich variety of technologically relevant behaviour displayed by metallic oxides (eg superconductivity, colossal magnetoresistance and other unusual magnetic effects), so this is an important issue. The predictions of FLT are most robust in the T->0 limit, and a definitive study requires difficult and challenging experiments performed to very low temperatures combined with theoretical work on the electronic structure of the same materials. Our goal is to subject carefully chosen oxides to a comprehensive, high resolution study involving measurement of the quasiparticle spectrum via quantum oscillations, 'tuning' the FLT-non FLT boundary as a function of externally controllable parameters such as pressure, disorder and chemical composition.
