“…In so doing, we use the very recent result suggested by [58,59] for the PDM-minimal-coupling and the PDM-momentum operator. Furthermore, we discuss the possibility of achieving the Landau quantization for such a system, and the separability of the problem in the cylindrical coordinates (ρ, φ, z), under azimuthal symmetrization, by considering that the field configurations and the PDM settings are purely radial dependent as in [54,55,[59][60][61]. In section III, we discuss a Landau levels analog for an electric quadrupole moment interacting with an external magnetic field in the absence of electric field.…”
