On the Stability of String Theory Vacua
Suvendu Giri, Luca Martucci, Alessandro Tomasiello
Vacuum compactifications may suffer from instabilities under small perturbations or tunnel effects; both are difficult to analyze. In this paper we consider the issue from a higher…
Black holes with spindles at the horizon
Suvendu Giri
We construct and solutions in F(4) gauged supergravity in six dimensions, where is a two dimensional manifold of non-constant curvat…
Re-examining the stability of rotating horizonless black shells mimicking Kerr black holes
Ulf Danielsson, Suvendu Giri
In arXiv:1705.10172 a string theory inspired alternative to gravitational collapse was proposed, consisting of a bubble of AdS space made up of ingredients from string theory. Thes…
Curing with hemlock: escaping the swampland using instabilities from string theory
Souvik Banerjee, Ulf Danielsson, Suvendu Giri
In this essay we will take a wonderful ride on a dark bubble with strings attached, which carries our universe out of the swampland and makes it realizable in the landscape of stri…
Dark bubbles and black holes
Souvik Banerjee, Ulf Danielsson, Suvendu Giri
In this paper we study shells of matter and black holes on the expanding bubbles realizing de Sitter space, that were proposed in arXiv:1807.01570. We construct explicit solutions…
