About Binghamton University, this university does not any rank in physics. But, about condensed matter group in this university, I think it is very strong! Stronger than some ranked universities. As a person who really cares about advisors and this topic: topological insulators, both theoretically and experimentally, which this university is really rich for this topic.
Do think this university is worth to attend? While you have an acceptance from 61 rank university?
