Holography of Information in a Ball of Finite Radius
Nava Gaddam, Ashik H
The principle of holography of information states that all information available in the bulk of asymptotically flat spacetime is also available near its boundary at spatial infinit…
Black hole - wormhole transitions in two dimensional string theory
Panos Betzios, Nava Gaddam, Olga Papadoulaki
We study charged black hole and wormhole solutions of Type 0A/IIA string theory in two dimensions. There is a competition between Euclidean wormholes and near extremal black holes…
Charged particle scattering near the horizon
Fabiano Feleppa, Nava Gaddam, Nico Groenenboom
We study Maxwell theory, in the presence of charged scalar sources, near the black hole horizon in a partial wave basis. We derive the gauge field configuration that solves Maxwell…
All near-horizon symmetries of the Schwarzschild black hole in linearised gravity
Ankit Aggarwal, Nava Gaddam
Asymptotic symmetries are known to constrain the infrared behaviour of scattering processes in asymptotically flat spacetimes. By the same token, one expects symmetries of the blac…
A toolbox for black hole scattering
Nava Gaddam, Nico Groenenboom
Hawking's free field theory is expected to break down after Page time. In previous work, we have shown that a primary dynamical reason for this breakdown is the dominance of gravit…
Baby Universes born from the Void
Panos Betzios, Nava Gaddam, Olga Papadoulaki
We propose a novel construction of a third quantised baby universe Hilbert space for the quantum gravity path integral. In contrast to the original description o…
