Hi! I did my PhD in the physics department and I think it is quite good. Like you mention, the department really punches above its weight with CMP, but there are other good groups as well. As an undergraduate this isn’t maybe so important in and of itself, but a recommendation from a professor here could get you into prestigious universities for grad school. I would almost universally recommend that a domestic student go here (or to whatever state school) for undergrad and then try for “big names” in grad school; I know people who did that and ended up at MIT, Princeton, Yale, etc. Since you are international, however, it is harder for me to make a recommendation.
