TL;DR

This paper explores the relativistic quantum behavior of charged spin-0 particles in a 4D curved space-time with a cosmic string, analyzing how external fields influence the Klein-Gordon equation and energy levels.

Contribution

It generalizes the Klein-Gordon equation to include external fields in a curved space-time with a cosmic string, revealing modifications to energy eigenvalues.

Findings

Energy eigenvalues are altered by the presence of external fields.

The Klein-Gordon oscillator behavior is studied in this curved background.

External fields impact the quantum dynamics of charged particles.

Abstract

In this work, we investigate the relativistic quantum dynamics of spin-0 massive charged particles in a 4D curved space-time, the generalization of a cosmic string space-time. We investigate the Klein-Gordon equation in the presence of external fields in the considered framework. We also investigate a quantum particle described by the Klein-Gordon oscillator in the curved background space-time in the presence of external fields. We see that the energy eigenvalues get modifies in comparison to the results obtained in a cosmic string space-time.
