Remarks on some quantum effects in the spacetime of a cosmic string

TL;DR

This paper investigates how a cosmic string's spacetime affects quantum particles, revealing modifications in energy spectra compared to flat spacetime, thus highlighting quantum effects induced by cosmic topological defects.

Contribution

It provides new insights into quantum behavior in curved spacetime around cosmic strings, including explicit energy spectrum calculations.

Findings

Energy spectra differ from flat spacetime values

Quantum effects are influenced by cosmic string topology

Potential-dependent spectral modifications

Abstract

We study the behaviour of a non-relativistic quantum particle interacting with different potentials, in the background spacetime generated by a cosmic string. We find the energy spectra for the quantum systems under consideration and discuss how they differ from their flat Minkowski spacetime values.
