A covariant polymerized scalar field in loop quantum gravity
Published 18 Feb 2021 in gr-qc and hep-th | (2102.09501v2)
Abstract: We propose a new polymerization scheme for scalar fields coupled to gravity. It has the advantage of being a (non-bijective) canonical transformation of the fields and therefore ensures the covariance of the theory. We study it in detail in spherically symmetric situations and compare to other approaches.
