Position-Space Renormalisation of the Energy-Momentum Tensor
Henrique Bergallo Rocha, Luigi Del Debbio, Andreas Jüttner +4
There is increasing interest in the study of nonperturbative aspects of three-dimensional quantum field theories (QFT). They appear as holographic dual to theories of (strongly cou…

Renormalization of the scalar energy-momentum tensor using the Wilson flow
Joseph K. L. Lee, Luigi Del Debbio, Elizabeth Dobson +6
In the holographic approach to cosmology, cosmological observables are described in terms of correlators of a three-dimensional boundary quantum field theory. As a concrete model,…
