R7-branes and AdS $_{9}$ solutions in type IIB

Giuseppe Dibitetto, Cameron Gibson, Nicolò Petri +1

We consider the recently found $AdS_{9}$ backgrounds in type IIB supergravity. We start by reviewing the solutions in a more convenient set of coordinates, which allows us t…

Holographic reconstruction for defect CFTs from $AdS_{p} \times S^{q}$ spacetimes

Federico Faedo, Nicolò Petri, Alessia Segati

We study defects in superconformal field theories using holography, focusing on the precise derivation of the defect observables from supergravity. We consider $\mathrm{AdS}_p \tim…

Towards AdS Distances in String Theory

Yixuan Li, Eran Palti, Nicolò Petri

The AdS Distance Conjecture proposes to assign a notion of distance between AdS vacua in quantum gravity. We perform some initial developments of this idea. We first propose more s…
