摘要
We analyse the interaction of an electron with a nonuniform electric field under the influence of a cut-off point induced by the topology of a spiral dislocation. We show that the presence of the cut-off point yields eigenvalues of energy which are infinitely degenerated. Besides, we show that the energy eigenvalues are influenced by the topology of the defect even though there is no interaction between the electron and the defect. Furthermore, we show that the influence of a cut-off point induced by the spiral dislocation topology gives rise to a non-null revival time associated with the radial quantum number.
