comment CFT: from States to Operators
Thank you - these are excellent resources which I hadn't checked. Bonus credit if you can point me towards a non-path-integral argument (just out of academic interest). The usual non-path-integral arguments seem somewhat non-rigorous, relying as they do on bootstrap-like ideas.

comment How do I obtain the SUSY Transformations from Poisson Brackets?
Have edited - I think this question should be left open for now, since it has got a conceptual basis and involves a concrete calculation that the OP has made some attempt at. I will provide an answer later when I get a moment!

comment What are the virtual particles generated during the Hawking radiation?
Seconding jinawee - the picture of virtual particle pairs is categorically not the right way to think about Hawking radiation. Quite obviously it must be wrong, because it is a loop level effect, and loops in QFT have to close, which they don't in this heuristic picture. You're much better off thinking about Hawking radiation as a horizon effect like the Unruh effect.

comment How to find frequency with only amplitude?
I think that this question shouldn't be closed because it highlights a genuine physical misunderstanding, and as such is interesting. Also tpg2114 has given a good answer which explains the concept well, without providing a solution.

You should clarify your question. If you are asking for examples of CFTs which are valid at any value of the coupling(s) then user2309840 has given a good answer above.
