Dynamical Formation of Spherical Domain Wall by Hawking Radiation and Spontaneous Charging-up of Black Hole

TL;DR

This paper investigates how Hawking radiation can lead to the formation of spherical domain walls around black holes, causing spontaneous charging-up of the black hole through charge transport mechanisms influenced by C- and CP-violation.

Contribution

It demonstrates the dynamical formation of spherical domain walls around black holes and introduces the concept of black hole charging-up via Hawking radiation and charge transport.

Findings

Spherical domain walls form around black holes with high Hawking temperature.

Electroweak and GUT walls are realistic cases of such formations.

Black holes can acquire significant hyper charge through this process.

Abstract

We discuss the Hawking radiation in the Higgs-Yukawa system and we show dynamical formation of a spherical domain wall around the black hole. The formation of the spherical wall is a general property of the black hole whose Hawking temperature is equal to or greater than the energy scale of the system. The formation of the electroweak wall and that of the GUT wall are shown as realistic cases. We also discuss a phenomenon of the spontaneous charging-up of the black hole. The Hawking radiation can charge-up the black hole itself by the charge-transportation due to the spherical wall when C- and CP-violation in the wall are assumed. The black hole with the electroweak wall can obtain a large amount of the hyper charge.
