U of Maryland has a strong plasma physics group, Professor Thomas Antonsen and others.https://www.ece.umd.edu/faculty/antonsen
Maryland also has a very top math and CS program, lots of biophysics, and quantum physics too.
Being close to Washington DC is a big plus for funding and U of Maryland's rank is very strong in physics.
Ohio State is also strong in math and physics.
Rochester, is way weaker for PhD programs but good for undergraduate programs in physics and optics.
