Late-time electric screening in dS from EAdS loops
Ernesto Bianchi, Sacha Ployet, Charlotte Sleight +1
We compute the one-loop gauge-field two-point functions analytically in scalar QED on dS for general dimension and scalar mass, using the EAdS reformulation of the in-in fo…
AdS amplitudes as CFT correlators
Maximo Bañados, Ernesto Bianchi, Ivan Muñoz +1
We show that AdS amplitudes are CFT correlators to all orders in the loop expansion by showing that they obey the conformal Ward identities. In particular, we provide explicit form…
Bulk renormalization and the AdS/CFT correspondence
Máximo Bañados, Ernesto Bianchi, Iván Muñoz +1
We develop a systematic renormalization procedure for QFT in anti-de Sitter spacetime. UV infinities are regulated using a geodesic point-splitting method, which respects AdS isome…
Quantum Scalar Theories in the AdS/CFT Correspondence
Ernesto Bianchi
This thesis contains original research on the conjectured AdS/CFT correspondence. Known are the holographic correlators resulting from this correspondence under its classical appro…
