The topological defect is modeled through a torsion-induced deformation of space, which modifies the effective metric without introducing curvature. By combining the minimal-coupling prescription in curved space with a radial ring confinement and a perpendicular magnetic field, we derive the effective radial Schr\\\"odinger problem, obtain the bound states, and evaluate the nonlinear susceptibilities within the electric-di","authors_text":"Carlos Magno O.
