We investigate a vacuum decay around a spinning seed black hole by using the Israel junction condition and conclude that the spin of black hole would suppress a vacuum decay rate compared to that for a non-spinning case, provided that the surface of vacuum bubble has its ellipsoidal shape characterized by the Kerr geometry. We also find out that in the existence of a near-extremal black hole, a false vacuum state can be more stabilized than the case of the Coleman-de Luccia solution. A few… 

False vacuum decay in a two-dimensional black hole spacetime

We study a false vacuum decay in a two-dimensional black hole spacetime background. The decay rate in the case that nucleation site locates at a black hole center has been calculated in the

False vacuum decay in rotating BTZ spacetimes

We analyse vacuum decay in rotating BTZ black hole spacetimes with the thin wall approximation. Possible parameter regions for the vacuum decay are clarified. We find that the nucleation rate is

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

On catalyzed vacuum decay around a radiating black hole and the crisis of the electroweak vacuum

False vacuum decay is a key feature in quantum field theories and exhibits a distinct signature in the early Universe cosmology. It has recently been suggested that the false vacuum decay is

Small-mass naked singularities censored by the Higgs field

We investigate a vacuum decay around an over-spinning naked singularity by using the Israel junction condition. We found that if the Higgs field develops the second minimum at higher energy scale, a

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

Hawking-Moss transition with a black hole seed

Abstract We extend the concept of Hawking-Moss, or up-tunnelling, transitions in the early universe to include black hole seeds. The black hole greatly enhances the decay amplitude, however, order

Black holes, oscillating instantons and the Hawking-Moss transition

Static oscillating bounces in Schwarzschild de Sitter spacetime are investigated. The oscillating bounce with many oscillations gives a super-thick bubble wall, for which the total vacuum energy

Vacuum decay in the Lorentzian path integral

We apply the Lorentzian path integral to the decay of a false vacuum and estimate the false-vacuum decay rate. To make the Lorentzian path integral convergent, the deformation of an integration

TLDR
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.

Connecting the Higgs potential and primordial black holes

It was recently demonstrated that small black holes can act as seeds for nucleating decay of the metastable Higgs vacuum, dramatically increasing the tunneling probability. Any primordial black hole

Gravitational Effects on and of Vacuum Decay

It is possible for a classical field theory to have two stable homogeneous ground states, only one of which is an absolute energy minimum. In the quantum version of the theory, the ground state of

Black holes as bubble nucleation sites

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

Rotating thin-shell wormhole from glued Kerr spacetimes

We construct a model of a rotating wormhole made by cutting and pasting two Kerr spacetimes. As a result, we obtain a rotating thin-shell wormhole with exotic matter at the throat. Two candidates for

Formation threshold of rotating primordial black holes

Within the framework that primordial black holes are formed by the direct gravitational collapse of large primordial density perturbations in the radiation dominated stage, we derive the threshold of

The electroweak vacuum need not be absolutely stable. For certain top-quarkand Higgs-boson masses in the minimal standard model, our vacuum is insteadmetastable with a lifetime exceeding the present

Spins of primordial black holes formed in the matter-dominated phase of the Universe

Angular momentum plays very important roles in the formation of primordial black holes in the matter-dominated phase of the Universe if it lasts sufficiently long. In fact, most collapsing masses are
