Do Cosmic Strings Give Rise to Vacuum Fluctuations ?
A. H. Bilge, M. Hortacsu, N. Ozdemir
TL;DR
This paper examines how cosmic strings influence vacuum fluctuations, proposing an alternative renormalization approach that suggests such strings do not induce vacuum fluctuations.
Contribution
It introduces a new interpretation of renormalization in the context of cosmic strings, challenging the conventional view of vacuum fluctuations caused by these topological defects.
Findings
The proposed renormalization method eliminates vacuum fluctuations in cosmic string spacetimes.
The interpretation differentiates between vacuum and non-vacuum spacetime contributions.
It questions previous assumptions about the role of cosmic strings in quantum field effects.
Abstract
The role of the identification of the vacuum and non-vacuum space-times in the computation of vacuum fluctuations in the presence of a cosmic string is discussed and an alternative interpretation of the renormalization is proposed. This procedure does not give rise to vacuum fluctuations.
