I applied to chemistry Ph.D. programs for fall of 2015, and I'm starting to freak out; if I get denied by all of them, I want to apply to Master's programs in physics next year. I want to work on theory, and I really crave the mathematical rigor in physics programs (hence, why I applied for theoretical chemistry). I've always wanted to take in-depth courses in E&M and QED.
Can a chemistry major be competitive for Master's programs in physics? Or is a Master's in physics kind of like in chemistry programs, where you apply for the Ph.D. and only get a Master's under certain circumstances? What would I do to become more competitive?
