I strongly suggest you consult professors at physics department for career advice, not only your current supervisor at chemistry department. This could give you extra information. Since you are in Oxford, there should be excellent local people to ask.
IMHO, the career path depends on what kind...
Hi,
I saw many templates for the cover letter of Ph.D. application. If I use them and do a little modification, is that OK or regard as a kind of plagiarization?
Thank you very much in advance!
At least, if you google 2(2+1) ÷ 2(2+1)
the result is 9

both multiplication and division belong to level 3
Introduction to Quantum Mechanics by David J Griffiths
Modern Quantum Mechanics by J. J. Sakurai
Personally I do not recommend Weinberg's book as a textbook... because the notation is so hard to handle..... it may better to serve as an important reference...
I heard from professors that for most interacting field theories (except phi^4 in 2+1 dimension), it has not been shown that they are consistent with the Wightman axioms. And proven realistic 3+1 dimensional interacting field theories will not lead to new physics (SUSY, string?...) anyway
You may need contour integral, Lagrange/Hamiltonian formulation of mechanics, classical electrodynamics especially specially relativity and the covariant formulation of Maxwell eqns, and a bit Lie group/algebra
Unless you are really interested in mathematician's QFT, e.g. Quantum Field Theory...
