“…Besides, the space around it has a solid angle deficit, and the same angle, independent of the impact parameter, deflects all light rays. After this study, several works have been developed in this direction, which include the study of the polarization and vacuum fluctuations [51][52][53], the relativistic motion of quantum oscillator [54][55][56], radiation, absorption and scattering of black holes [57][58][59], etc.…”

In this paper, we studied the nonrelativistic quantum mechanics of an electron in a spacetime containing a topological defect. We also considered that the electron is influenced by the Hulthén potential. In particular, we dealt with the Schrödinger equation in the presence of a global monopole. We obtained approximate solutions for the problem, determined the scattering phase shift and the S-matrix, and analyzed bound states.
