A bstractWe consider the effect of inhomogeneities on the rate of false vacuum decay. Modelling the inhomogeneity by a black hole, we construct explicit Euclidean instantons which describe the nucleation of a bubble of true vacuum centred on the inhomogeneity. We find that inhomogeneity significantly enhances the nucleation rate over that of the Coleman-de Luccia instanton — the black hole acts as a nucleation site for the bubble. The effect is larger than previously believed due to the… 

Vacuum decay and bubble nucleation in the anti-de Sitter black holes

We study the vacuum decay and the bubble nucleation in the anti-de Sitter black holes. In the bubble nucleation spacetime, the interior and the exterior of the bubble wall are described by two

Black holes seeding cosmological phase transitions

We consider a generic first-order phase transition at finite temperature and investigate to what extent a population of primordial black holes, of variable masses, can affect the rate of bubble

Black holes, vacuum decay and thermodynamics

In this thesis we study two fairly different aspects of gravity: vacuum decay seeded by black holes and black hole thermodynamics. The first part of this work is devoted to the study of black holes

Thin-shell bubbles and information loss problem in anti de Sitter background

A bstractWe study the motion of thin-shell bubbles and their tunneling in anti de Sitter (AdS) background. We are interested in the case when the outside of a shell is a Schwarzschild-AdS space

False Vacuum Decay Catalyzed by Black Holes

False vacuum states are metastable in quantum field theories, and true vacuum bubbles can be nucleated due to the quantum tunneling effect. It was recently suggested that an evaporating black hole

Stationary Vacuum Bubble in a Kerr-de Sitter Spacetime

We study false vacuum decay in a black hole (BH) spacetime with an angular momentum. Considering the false vacuum region described by a Kerr-de Sitter geometry, under the thin wall approximation, we

Vacuum decay in the presence of a cosmic string

We study the false vacuum decay and bubble nucleation in the presence of a cosmic string in dS spacetime. A cosmic string induces a deficit angle in spacetime around itself so the nucleated bubble

Vacuum metastability with black holes

A bstractWe consider the possibility that small black holes can act as nucleation seeds for the decay of a metastable vacuum, focussing particularly on the Higgs potential. Using a thin-wall bubble

Tunneling between Schwarzschild–de Sitter vacua

We examine the effect of static primordial black holes on vacuum decay. In particular, we compare the tunneling rates between vacua of different values of the cosmological constant and black hole

Cosmography of KNdS black holes and isentropic phase transitions

We present a new analysis of Kerr–Newman–deSitter black holes in terms of thermodynamic quantities that are defined in the observable portion of the Universe; between the black hole and cosmological

It thus appears that a black hole can act as an effective nucleation center for a first-order vacuum phase transition and it will be more difficult (require more ``fine-tuning'' of the potential) than was previously believed to achieve supercooling of a false-vacuum state.

Limits on New Physics from Black Holes

Black holes emit high energy particles which induce a finite density potential for any scalar field ϕ coupling to the emitted quanta. Due to energetic considerations, ϕ evolves locally to minimize

Black holes initiate false-vacuum decay.

It is found that in the presence of a black hole in a false vaccum the process of spontaneous nucleation of a bubble around a black Hole proceeds at a tremendously faster rate than that of an empty O(4)-invariant true phase bubble.

Black Holes in Theories with Large Extra Dimensions

We start by reviewing the existing literature on the creation of black holes during high-energy particle collisions, both in the absence and in the presence of extra, compact, spacelike dimensions.

If theories of high-energy physics such as spontaneous symmetry breaking and quantum chromodynamics are correct, then exploding black holes will be surrounded by phase-transition bubbles or

Two tunnels to inflation

We investigate the formation via tunneling of inflating (false-vacuum) bubbles in a true-vacuum background, and the reverse process. Using effective potentials from the junction condition formalism,

Time dependent black holes and scalar hair

We show how to correctly account for scalar accretion onto black holes in scalar field models of dark energy by a consistent expansion in terms of a slow roll parameter. At leading order, we find an

Stability, tunneling and flux changing de Sitter transitions in the large volume string scenario

A bstractWe study the non-perturbative stability of the Large Volume Scenario (LVS) of IIB string compactifications, by analysing transitions mediated by the Brown-Teitelboim (BT) brane nucleations

Dynamics and instability of false vacuum bubbles

This paper examines the classical dynamics of false-vacuum regions embedded in surrounding regions of true vacuum, in the thin-wall limit. The dynamics of all generally relativistically allowed
