Minimum length (scale) in quantum field theory, generalized uncertainty principle and the non-renormalisability of gravity
The notions of minimum geometrical length and minimum length scale are discussed with reference to correlation functions obtained from in-in and in-out amplitudes in quantum field theory. Whereas the in-in propagator for metric perturbations does not admit the former, the in-out Feynman propagator s...
