We studied the anti-evaporation of a degenerate Schwarzschild–de Sitter black hole (so-called Nariai space-time) in modified F(R) gravity. We analyze the perturbations in the Nariai black hole and find that anti-evaporation may occur in F(R) gravity even at a classical level. For several power-law F(R) gravities which may describe the inflation and/or dark energy eras, we presented the theory parameter bounds for the occurrence of anti-evaporation and conjectured creation of an infinite number… 

The fate of Schwarzschild-de Sitter Black Holes in $f(R)$ gravity

The semiclassical effects of antievaporating black holes can be discussed in the framework of $f(R)$ gravity. In particular, the Bousso-Hawking-Nojiri-Odinstov antievaporation instability of

Reissner–Nordström Anti-de Sitter Black Holes in Mimetic F(R) Gravity

In this paper, we study under which conditions the Reissner–Nordstrom anti-de Sitter black hole can be a solution of the vacuum mimetic F ( R ) gravity with Lagrange multiplier and mimetic scalar

(Anti)evaporation of Dyonic Black Holes in string-inspired dilaton $f(R)$-gravity

We discuss dyonic black hole solutions in the case of $f(R)$-gravity coupled with a dilaton and two gauge bosons. The study of such a model is highly motivated from string theory. Our Black Hole

Evaporation and Antievaporation Instabilities

The purpose of this review is to provide an introduction to conceptual and technical aspects of (anti)evaporation effects, while discussing problems that are still open.

A Note on Schwarzschild de Sitter Black Holes in Mimetic $F(R)$ Gravity

In this brief note we investigate the conditions under which a Schwarzschild de Sitter black hole spacetime is a solution of the mimetic $F(R)$ gravity with Lagrange multiplier and potential. As we

Suppression of Bekenstein-Hawking radiation in $f(T)$-gravity

We discuss semiclassical Nariai black holes in the framework of $f(T)$-gravity. For a diagonal choice of tetrades, stable Nariai metrics can be found, emitting Bekenstein-Hawking radiation in

Extremal Cosmological Black Holes in Horndeski Gravity and the Anti-Evaporation Regime

Extremal cosmological black holes are analysed in the framework of the most general second order scalar-tensor theory, the so-called Horndeski gravity. Such extremal black holes are a particular case

Anti-evaporation and evaporation of an n -dimensional Reissner-Nordström black hole

We generalize $f(R)$-theory of anti-evaporation/evaporation for a Reissner-Nordstr\"om black hole in $n$-dimensional space-time. We consider non-linear conformally invariant Maxwell field. By



(Anti)evaporation of Schwarzschild-de Sitter black holes

We study the quantum evolution of black holes immersed in a de Sitter background space. For black holes whose size is comparable to that of the cosmological horizon, this process differs

Quantum evolution of Schwarzschild-de Sitter (Nariai) black holes

We calculate the one-loop effective action for conformal matter (scalars, spinors, and vectors) on spherically symmetric background. Such an effective action (in the large N approximation and

Nonlinear evolution of de Sitter space instabilities

We investigate the quantum evolution of large black holes that nucleate spontaneously in de Sitter space. By numerical computation in the s-wave and one-loop approximations, we verify claims that

Black Holes in f(R) theories

In the context of f(R) theories of gravity, we address the problem of finding static and spherically symmetric black hole solutions. Several aspects of constant curvature solutions with and without

Instability of a rotating black hole in a limited form of f(R) gravity

We investigate the stability of $f(R)$-rotating (Kerr) black hole obtained from a limited form of $f(R)$ gravity. In order to avoid the difficulty of handling fourth order linearized equations, we

Stability analysis of f(R)-AdS black holes

We study the stability of the f(R)-AdS (Schwarzschild–AdS) black hole obtained from f(R) gravity. In order to resolve the difficulty of solving fourth-order linearized equations, we transform f(R)

Stability of f(R) black holes

We investigate the stability of an $f(R)$ (Schwarzschild) black hole obtained from the $f(R)$ gravity. It is difficult to carry out the perturbation analysis around the black hole because the

Quantum Dilatonic Gravity in d=2,4 and 5 Dimensions

We review (mainly) quantum effects in the theories where the gravity sector is described by metric and dilaton. The one-loop effective action for dilatonic gravity in two and four dimensions is
