Hello all, I am rather new to these forums, and I have a question about lateral transfer between chemistry and physics. First, my background pertaining to physics: MATH: 3 semesters calculus 1 semester each: ordinary differential equations, linear algebra, abstract algebra, probability and statistics, and a course in mathematical proofs and logic PHYSICS: General physics 1 and 2. These were at a weak school, so I don't feel I know them very well. 1 semester mathematical physics (Mary Boas's book) 1 semester E & M (Griffith's book) CHEMISTRY: Physical chemistry 1 and 2. First semester was thermodynamics, second was (mostly) an introduction to quantum mechanics. Quantum Chemistry Inorganic Chemistry Other chemistry courses leading to BS in chemistry As I've progressed in chemistry, I've realized that the aspects I enjoy the most of chemistry are the ones closest to physics. I've already applied to several theoretical chemistry PhD programs (and been accepted to one rather good one), so I don't plan on applying to physics PhD programs as well, but my questions are as follows: 1) If, as I begin graduate school, I continue to find that my interests tend toward work heavy in physics level QM-i.e. beyond things like DFT, ab initio methods, etc., in such fields as quantum field theory, could I just study it in the chemistry PhD program, possibly under a physicist? 2) If, once I begin a chemistry PhD program, I wish to laterally transfer to physics, how difficult would this be? Obviously, this could depend a great deal on the school I attend, but if anyone has any general idea I'd be interested. 3) And, most important of all, with my background in physics, could I survive graduate level physics work? Any input from those familiar with this type of situation is much appreciated.
