Estimating global charge violating amplitudes from wormholes
Ibrahima Bah, Yiming Chen, Juan Maldacena
We consider the scattering of high energy and ultra relativistic spherically symmetric shells in asymptotically AdS spacetimes. We analyze an exclusive amplitude where a single…
Imaging Topological Solitons: the Microstructure Behind the Shadow
Pierre Heidmann, Ibrahima Bah, Emanuele Berti
We study photon geodesics in topological solitons that have the same asymptotic properties as Schwarzschild black holes. These are coherent states in string theory corresponding to…
A Panorama Of Physical Mathematics c. 2022
Ibrahima Bah, Daniel S. Freed, Gregory W. Moore +3
What follows is a broad-brush overview of the recent synergistic interactions between mathematics and theoretical physics of quantum field theory and string theory. The discussion…
Non-BPS Bubbling Geometries in AdS
Ibrahima Bah, Pierre Heidmann
We construct large classes of non-BPS smooth horizonless geometries that are asymptotic to AdSST in type IIB supergravity. These geometries are supported by…
Non-Invertible Symmetries from Holography and Branes
Fabio Apruzzi, Ibrahima Bah, Federico Bonetti +1
We propose a systematic approach to deriving symmetry generators of Quantum Field Theories in holography. Central to this are the Gauss law constraints in the Hamiltonian quantizat…
Aspects of Irregular Punctures via Holography
Ibrahima Bah, Federico Bonetti, Emily Nardoni +1
We present new families of solutions in M-theory preserving 4d supersymmetry. We perform a systematic analysis of holographic observables for these solut…
Snowmass Whitepaper: Physical Mathematics 2021
Ibrahima Bah, Daniel Freed, Gregory W. Moore +3
This is a Snowmass whitepaper on physical mathematics. It briefly summarizes and highlights some of the key questions drawn from a much more extensive essay, by the same authors, e…
Schwarzschild-like Topological Solitons
Ibrahima Bah, Pierre Heidmann, Peter Weck
We construct the first class of topological solitons in gravity that are supported by internal electromagnetic flux with vanishing net charges. The solutions are obtained in a six-…
Stability of topological solitons, and black string to bubble transition
Ibrahima Bah, Anindya Dey, Pierre Heidmann
We study the existence of smooth topological solitons and black strings as locally-stable saddles of the Euclidean gravitational action of five dimensional Einstein-Maxwell theory.…
