Quantum nucleation of black hole mimickers via chaos dominated tunneling
Ulf Danielsson, Suvendu Giri, Vyshnav Mohan +1
Black hole mimickers, ultracompact horizonless objects, have been proposed as alternatives to black holes in a variety of settings, including extensions of general relativity and s…
Dark bubbles, dark dimensions and fat gravitons
Ulf Danielsson, Suvendu Giri
The dark bubble model explains the existence of a positive cosmological constant by making explicit use of the instabilities underlying the de Sitter swampland conjectures to make…
Self-gravitating electromagnetic waves in the dark bubble model
Ulf Danielsson, Daniel Panizo, Vincent Van Hemelryck
We construct embeddings of gravitational and electromagnetic waves in the dark bubble scenario using pp-wave geometries in AdS5, motivated by the fact that pp-wave spacetimes often…
