R7-branes and AdS solutions in type IIB
Giuseppe Dibitetto, Cameron Gibson, Nicolò Petri +1
We consider the recently found 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 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…

Defects in 4d SCFTs from supergravity and holographic renormalization
Federico Faedo, Nicolò Petri, Alessia Segati
Type IIB string theory admits Janus solutions connecting vacua. These geometries correspond to interface conformal field theories and are naturally described in five…
