Project objective

Research objectives and content The aim of this proposal is to investigate transport in mesoscopic superconducting hybrid structures in the presence of electron-electron interactions. We shall study the effect on the electron states of the electron-electron interaction and the boundary conditions originating from interfaces between normal and superconducting regions. I shall start by analysing one of the simplest situations, that being a semi-infinite normal system in contact with a superconductor, and then progress to more complex and experimentally relevant geometries such as mesoscopic loops with superconducting inclusions and normal metal (N) - insulator (I) - superconductor (S) structures. We shall examine how interactions effect the superconducting proximity effect and what effect this has on transport in N - I - S and Andreev interferometer structures. Training content (objective, benefit and expected impact) I shall combine my knowledge of transport in hybrid superconducting structures with the expertise at the host institution in interacting electron systems. This will involve the understanding of different models of interacting electron systems and the techniques that are used to solve them (including renormalisation group, equation-of-motion and strong-coupling approaches to interacting systems). Links with industry / industrial relevance (22) This area of research is receiving increasing amounts of attention by the electronics industry with an eye on the production of new electronic devices for the 21 st century.
