Islands and Light Gravitons in type IIB String Theory
Saskia Demulder, Alessandra Gnecchi, Ioannis Lavdas +1
We consider the setup of an evaporating black hole in AdS coupled to an external bath, embedded in type IIB string theory. We study quantum extremal islands in these backgrou…
Mixed moduli in 3d N=4 higher-genus quivers
Ioannis Lavdas, Bruno Le Floch
We analyze exactly marginal deformations of 3d N=4 Lagrangian gauge theories, especially mixed-branch operators with both electric and magnetic charges. These mixed-branch moduli c…
Holomorphic boundary conditions for topological field theories via branes in twisted supergravity
Ilka Brunner, Ioannis Lavdas, Ingmar Saberi
Three-dimensional supersymmetric field theories admit a natural class of chiral half-BPS boundary conditions that preserve supersymmetry. While…
Massive gravitons on the Landscape and the AdS Distance Conjecture
Ioannis Lavdas, Dieter Lust
This work regards IIB string theory embeddings of massive and bi-metric gravity where the spectrum of the theory includes multiple massive gravitons. The corresponding ge…
Marginal Deformations of 3d N=4 Linear Quiver Theories
Constantin Bachas, Ioannis Lavdas, Bruno Le Floch
We study superconformal deformations of the theories of Gaiotto-Hanany-Witten, paying special attention to mixed-branch operators with both electrically- and m…
Massive Anti-de Sitter Gravity from String Theory
Constantin Bachas, Ioannis Lavdas
We study top-down embeddings of massive Anti-de Sitter (AdS) gravity in type-IIB string theory. The supergravity solutions have a AdS fiber warped over a manifold M whose s…
Quantum Gates to other Universes
Constantin Bachas, Ioannis Lavdas
We present a microscopic model of a bridge connecting two large Anti-de-Sitter Universes. The Universes admit a holographic description as three-dimensional supersymme…
