I'm a novice in Loop Quantum Gravity, so please bear with me if this is a trivial question. As far as I know, LQG is usually formulated non-perturbatively, but is there also a perturbative approach in the sense that we use a series expansion in order to calculate vacuum expectation values? Are there Feynman diagrams? Does this even make sense?(adsbygoogle = window.adsbygoogle || []).push({});
