Comments on double trace deformations and boundary conditions
William Cottrell, Akikazu Hashimoto
We study the UV dynamics of deformed conformal field theories formulated as a deformation of generating functions. We explore the issue of non-perturbative completion o…
Stability and boundedness in AdS/CFT with double trace deformations II: Vector Fields
William Cottrell, Akikazu Hashimoto, Andrew Loveridge +1
We extend the analysis of boundedness and stability, initiated for scalar fields in anti de Sitter space in a previous work, to the case of vector fields. We show that the double t…
Gravitational Decoupling and Picard-Lefschetz
Jon Brown, Alex Cole, William Cottrell +1
In this work, we consider tunneling between non-metastable states in gravitational theories. Such processes arise in various contexts, e.g., in inflationary scenarios where the inf…
Complexity is Simple
William Cottrell, Miguel Montero
In this note we investigate the role of Lloyd's computational bound in holographic complexity. Our goal is to translate the assumptions behind Lloyd's proof into the bulk language.…
Stability and boundedness in AdS/CFT with double trace deformations
Steven Casper, William Cottrell, Akikazu Hashimoto +2
Scalar fields on the bulk side of AdS/CFT correspondence can be assigned unconventional boundary conditions, related to the conventional one by Legendre transform. One can further…
Weak Gravity Conjecture and Extremal Black Holes
William Cottrell, Gary Shiu, Pablo Soler
Motivated by the desire to improve our understanding of the Weak Gravity Conjecture, we compute the one-loop correction of charged particles to the geometry and entropy of extremal…
