Hi All, I'm very close to having to start thinking about what and where my PhD will involve. I'm interested in Theoretical Condensed Matter, (possibly topological superconductors/insulators ) and was just wondering if anyone knows from experience which universities have very active research groups in that field (Or can talk about their experience at a specific university). Do a lot of universities (i.e. Cambridge) have interviews/tests for postgraduate physics applications, or can it be mainly by reference? My current grades at undergraduate are very good and I've done a lot or research work experience in general condensed matter and quantum information, has that sort of thing helped anyone significantly in getting a PhD place? Thanks.
