Not 100% sure yet, but it will probably be in Condensed Matter.

Does anyone know how I can determine how good similar research groups are in different Universities?

Im in the UK hoping to apply for Physics PhD's in the UK. I know about the 2001 RAE marks that rank each dept. But these are several years out of date now and only rank the dept not the research group that it consists of. Are there any other statistics out there I can look at?

I know that a good way to do this is to look at citation scores. But I've no idea where to look for them.

Any suggestions are greatly welcomed.

Cheers!!
