Query: On the missing magnetic flux and topological effects of a screw
  dislocation on a charged particle in an inhomogeneous magnetic field   We study the interaction of an electron/hole with inhomogeneous magnetic
field in the presence of a screw dislocation. We consider the internal
structure of the defect, i.e., we consider the core that gives rise to a finite
size to the defect. In addition, we assume that this core determines a
forbidden region for the electron/hole. Then, we solve the Schr\"odinger
equation and show that an Aharonov-Bohm-type effect arises from the influence
of the topological defect and the missing magnetic flux on the eigenvalues of
energy.
