In this study,we focus into the non-relativistic wave equation described by the Schrödinger equation,specifically considering angular-dependent potentials within the context of a topological defect background generated by a cosmic string.Our primary goal is to explore quasi-exactly solvable problems by introducing an extended ring-shaped potential.We utilize the Bethe ansatz method to determine the angular solutions,while the radial solutions are obtained using special functions.Our findings demonstrate that the eigenvalue solutions of quantum particles are intricately influenced by the presence of the topological defect of the cosmic string,resulting in significant modifications compared to those in a flat space background.The existence of the topological defect induces alterations in the energy spectra,disrupting degeneracy.Afterwards,we extend our analysis to study the same problem in the presence of a ring-shaped potential against the background of another topological defect geometry known as a point-like global monopole.Following a similar procedure,we obtain the eigenvalue solutions and analyze the results.Remarkably,we observe that the presence of a global monopole leads to a decrease in the energy levels compared to the flat space results.In both cases,we conduct a thorough numerical analysis to validate our findings.
