# Holes in the walls: Primordial black holes as a solution to the cosmological domain wall problem

@article{Stojkovic2005HolesIT, title={Holes in the walls: Primordial black holes as a solution to the cosmological domain wall problem}, author={Dejan Stojkovic and Katherine Freese and Glenn D Starkman}, journal={Physical Review D}, year={2005}, volume={72}, pages={045012} }

We propose a scenario in which the cosmological domain wall and monopole problems are solved without any fine tuning of the initial conditions or parameters in the Lagrangian of an underlying filed theory. In this scenario domain walls sweep out (unwind) the monopoles from the early universe, then the fast primordial black holes perforate the domain walls, change their topology and destroy them. We find further that the (old vacuum) energy density released from the domain walls could alleviate…

Black holes escaping from domain walls

- Physics

Previous studies concerning the interaction of branes and black holes suggested that a small black hole intersecting a brane may escape via a mechanism of reconnection. Here we consider this problem…

Dynamical solution to the axion domain wall problem

Primordial black holes (PBHs) are a profound signature of primordial cosmological structures and provide a theoretical tool to study nontrivial physics of the early Universe. The mechanisms of PBH…

Cosmic implications of a low-scale solution to the axion domain wall problem

The post-inflationary breaking of Peccei-Quinn (PQ) symmetry can lead to the cosmic domain wall catastrophe. In this Letter we show how to avoid domain walls implementing the Instanton Interference…

Modified hoop conjecture in expanding spacetimes and primordial black hole production in FRW universe

According to a variant of the hoop conjecture, if we localize two particles within the Schwarzschild radius corresponding to their center of mass energy, then a black hole will form. Despite a large…

Clustering of primordial black holes: Basic results

Energy flux through the horizon in the black hole-domain wall systems

We study various configurations in which a domain wall (or cosmic string), described by the Nambu-Goto action, is embedded in a background space-time of a black hole in $(3+1)$ and higher dimensional…

Sweeping away the monopole problem

We propose a new solution to the cosmological monopole problem in which domain walls sweep away the magnetic monopoles and subsequently decay. The solution does not require extensive fine tuning or…

Pair creation of black holes by domain walls.

It is found that the creation of nonorientable black hole solutions can be mediated by Euclidean instantons and that in addition if one is prepared to consider entirely Lorentzian no-boundary-type contributions to the path integral then mutually accelerating pairs may be created even in the neutral case.
