Quantum (in)stability of maximally symmetric space-times
Jewel K. Ghosh, Elias Kiritsis, Francesco Nitti +1
Classical gravity coupled to a CFT (matter) is considered. The effect of the quantum dynamics of matter on gravity is studied around maximally symmetric spaces (flat, de Sitter…
Holographic QFTs on AdS, wormholes and holographic interfaces
A. Ghodsi, J. K. Ghosh, E. Kiritsis +2
We consider three related topics: (a) Holographic quantum field theories on AdS spaces. (b) Holographic interfaces of flat space QFTs. (c) Wormholes connecting generically differen…
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…
