Hi, I am planning on applying to graduate school for condensed matter physics. I'm not entirely sure how I should narrow down my choices though. I have a good GPA, three summers of research experience in different areas (though no publications as of yet, but hoping to have one possibly before the end of the year) and I believe I can get good recommendation letters from Professors. SO I think I have at least a *reasonable* chance of getting into a decent program, but how does one know which programs are good or not? One idea I had was to just apply at schools where I see authors of good or influential papers in the field are located, but I'm not sure how smart that is. Is there rankings based on specific sub-fields that in *your* opinion are reliable? Maybe there exists websites where grad students can pitch or warn against their school of choice? Any tips appreciated.
