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,…

Renormalization of the energy-momentum tensor in three-dimensional scalar theories using the Wilson flow
Luigi Del Debbio, Elizabeth Dobson, Andreas Jüttner +6
A nonperturbative determination of the energy-momentum tensor is essential for understanding the physics of strongly coupled systems. The ability of the Wilson flow to eliminate di…
