I've got to start applying for PhD's in the next few weeks and I've got some ideas fo the sort of areas I might pursue in HEP or gravitation, but was wondering if anyone on here could think of any other areas that have interesting problems that need working on that are perhaps eclipsed at the moment by string theory etc.
I'm thinking I might apply for a few in superconductivity and quantum chaos/foundations of QM aswell.
So, any interesting suggestions? I'm open to most things as long as it's theory and not experimental (sox and labs do not get on well together).
Cheers, sox.
