Festina lente:1 EFT constraints from charged black hole evaporation in de Sitter

  title={Festina lente:1 EFT constraints from charged black hole evaporation in de Sitter},
  author={Miguel Montero and Thomas Van Riet and G. Venken},
  journal={arXiv: High Energy Physics - Theory},
In the Swampland philosophy of constraining EFTs from black hole mechanics we study charged black hole evaporation in de Sitter space. We establish how the black hole mass and charge change over time due to both Hawking radiation and Schwinger pair production as a function of the masses and charges of the elementary particles in the theory. We find a lower bound on the mass of charged particles by demanding that large charged black holes evaporate back to empty de Sitter space, in accordance… Expand

Dilatonic (Anti-)de Sitter Black Holes and Weak Gravity Conjecture
Einstein-Maxwell-dilaton theory with non-trivial dilaton potential is known to admit asymptotically flat and (Anti-)de Sitter charged black hole solutions. We investigate the conditions for theExpand
Universal thermodynamic extremality relations for charged AdS black hole surrounded by quintessence
The perturbation correction of general relativity has obtained the general relationship between entropy and extremality. The relation was found to exactly hold for the charged AdS black hole, andExpand
The gravitino and the swampland
We propose a new swampland conjecture stating that the limit of vanishing gravitino mass corresponds to the massless limit of an infinite tower of states and to the consequent breakdown of theExpand
Cosmic censorship and the evolution of d -dimensional charged evaporating black holes
The cosmic censorship conjecture essentially states that naked singularities should not form from generic initial conditions. Since black hole parameters can change their values under HawkingExpand
de Sitter Bubbles and the Swampland
A number of Swampland conjectures and in particular the Trans-Planckian Censorship Conjecture (TCC) suggest that de Sitter space is highly unstable if it exists at all. In this paper we constructExpand
Schwinger effect from near-extremal black holes in (A)dS space
We study the Schwinger effect in near-extremal Reissner-Nordstr\"om black holes with electric and/or magnetic charges in (anti-)de Sitter (AdS) space. The formula for the Schwinger effect takes aExpand

Recent developments regarding the Weak Gravity Conjecture suggest the existence of a quantum-gravitational version of Cosmic Censorship. We explore the form that this "quantum Censorship" might takeExpand

Scalar tachyonic instabilities in gravitational backgrounds: Existence and growth rate

Charged particle production rate from cosmic censorship in dilaton black hole spacetimes
Abstract Hiscock and Weems showed that under Hawking evaporation, an isolated asymptotically flat Reissner-Nordström (RN) black hole evolves in a surprising manner: if it starts with a relativelyExpand
