Bridging worldsheet CFTs and wormholes

Journal of High Energy Physics
I provide multiple examples of conformal field theories (CFTs) on the world-sheet that describe string propagation in target space wormholes connecting two disjoint asymptotic manifolds.

Wormholes immersed in rotating matter

Physics Letters B, 2018
We demonstrate that rotating matter sets the throat of an Ellis wormhole into rotation, allowing for wormholes which possess full reflection symmetry with respect to the two asymptotically flat spacetime regions.

Half-wormholes in a supersymmetric SYK model

Journal of High Energy Physics
We identify half-wormhole contributions to the non averaged N $$ \mathcal{N} $$ = 1 supersymmetric SYK model in which time has been reduced to a point. As in previously studied examples, the inclusion of half-wormholes restores factorisation in the large

Traversable Schwarzschild-like wormholes

European Physical Journal C: Particles and Fields, 2017
In this paper we study relativistic static traversable wormhole solutions which are a slight generalization of Schwarzschild wormholes. In order to do this we assume a shape function with a linear dependence on the radial coordinate r.

Lessons on eternal traversable wormholes in AdS [PDF]

Journal of High Energy Physics, 2019
We attempt to construct eternal traversable wormholes connecting two asymptotically AdS regions by introducing a static coupling between their dual CFTs.

Axion-de Sitter wormholes [PDF]

, 2023
We construct wormholes supported by axion flux in the presence of a positive cosmological constant. The solutions describe compact, one-handle bodies colloquially known as kettlebell geometries.

Finite action principle and wormholes [PDF]

, 2023
In this work, we elaborate on the finite action for wormholes in higher derivative theories as well as for wormholes. Both non-traversable and traversable wormholes in theories with higher curvature invariants posses finite action.In this work, we ...

Analog model for Euclidean wormholes effects [PDF]

, 2023
Using results of statistical field theory for systems with an anisotropic disorder, we present an analog model for Euclidean wormholes and topological fluctuation effects in a Riemannian space Md.

AdS Wormholes from AdS/Ricci-flat Correspondence [PDF]

, 2023
We discuss the Wormholes in general dimensions by studying the Einstein-phantom scalar field with and without the cosmological constant. Solving AdS wormholes in general dimension is hard due to the nonlinear nature of the theory.

Generating Geodesic Flows and Supergravity Solutions [PDF]

, 2009
We consider the geodesic motion on the symmetric moduli spaces that arise after timelike and spacellike reductions of supergravity theories. The geodesics correspond to timelike respectively spacelike p-brane Solutions when they are lifted over a p ...
