I have been looking around for a soft derivation with a bit of detail for boson and fermion path integrals that I could understand. I have a passing knowledge generally of what a path integral is in Quantum mechanics but I don't understand any of the derivations that I have come across for boson and fermion path integrals.
It would be nice if perhaps a very simple example of each in use is demonstrated with some explanation. Is there a scenario where a mixture of the two is used?

  • $\begingroup$ Did you see the Peskin Schroeder one? He does the Boson path integral in details $\endgroup$ – Slereah Aug 15 '15 at 10:00
  • $\begingroup$ Actually, I don't have that book, but I found a quantum statistical mechanics introduction here statphys12.inln.cnrs.fr/IMG/pdf/Muramatsu.pdf , and can't quite make sense of it even at this level. $\endgroup$ – user37343 Aug 16 '15 at 14:39
