Applied Physics --> Physics? Hi, Is it possible and feasible to switch from Applied Physics (say with a PhD, having worked on accelerator physics) to 'pure' Physics (say theory, or experiment, in high energy physics)? I'm trying to weigh my options as a senior undergrad in EE wanting to make a career switch to Physics. But I presume I have a better chance in Applied Physics programs rather than Physics programs. (This, despite having taken courses on QM, Relativity and QFT, since I lack research experience in physics.) Since a few schools do not allow applying to multiple programs, I have to make up my mind. Thanks for your help. Cheers!
