I am applying to grad schools now, in physics dept. I have been doing my undergrad research on high energy and astrophysics. But recently I have started to gain a lot of interest in condensed matter physics. If I get accepted to grad school, I will be selected on the basis of my massive undergrad research which is mostly focused on high energy physics. But, I want to do my PhD on condensed matter. But one of my main concern is finding an advisor. I am worried that the professors in top tier universities may not comply with it.
Is it possible to persuade advisors in condensed matter to guide me? (especially in a top tier university)
If yes, how easy is it ?
I am not so sure about it....But is this thing really common among grad students?
