Guest kay Posted January 22, 2003 Share Posted January 22, 2003 I know that operator product expansions exist in Quantum Field Theory (Wilson-Kadanoff expansion) and in conformal field theory. I'd like to know if anyone knows a reference (or anything) about operator product expansion in many body quantum mechanics? Hopefiully my question is not too naive....
