A charged particle with magnetic moment in a medium with a disclination

Using a description of defects in solids in terms of three-dimensional gravity, we will consider a charged quantum particle with spin-1/2 in the field of a finite magnetic flux in a space with a disclination. It will be demonstrated that the change in topology caused by the defect produces modifications in the energy spectrum of a charged particle which in this case depends on the magnetic flux and on the global aspects.
