The unfortunate truth is that even among good theoretical physicists there are few who would be able to teach such a course. The main reason is that a mathematical description of some of these things is still scattered in the research literature. The best attempt that I am aware of is the special year at Princeton in the 90s it produces a fantastic two volume collection of lectures “quantum fields and strings: a course for mathematicians”. Weinberg’s three part book on QFT is also pretty nice.
