Weyl-Ambient Geometries
Weizhen Jia, Manthos Karydas, Robert G. Leigh
Weyl geometry is a natural extension of conformal geometry with Weyl covariance mediated by a Weyl connection. We generalize the Fefferman-Graham (FG) ambient construction for conf…

A Lindbladian for exact renormalization of density operators in QFT
Samuel Goldman, Nima Lashkari, Robert G. Leigh
In arXiv:1609.03493, the authors extended the exact renormalization group (ERG) to arbitrary wave-functionals in quantum field theory (QFT). Applying this formalism, we show that t…
