J.R.S.Nascimento, Inyong Cho, Alexander Vilenkin
TL;DR
This paper investigates how a charged superconducting cosmic string creates a large electric field that causes vacuum instability, leading to a charged condensate that screens the string's charge, analyzed via the Thomas-Fermi method.
Contribution
It introduces a detailed analysis of vacuum condensate formation around charged cosmic strings using the Thomas-Fermi approach, highlighting the screening effect.
Findings
Charged vacuum condensate screens the cosmic string's electric charge.
Vacuum instability occurs due to the large electric field.
Thomas-Fermi method effectively models the condensate structure.
Abstract
A charged superconductiong cosmic string produces an extremely large electric field in its vicinity. This leads to vacuum instability and to the formation of a charged vacuum condensate which screens the electric charge of the string. We analyze the structure of this condensate using the Thomas-Fermi method.
