Relativistic Quantum Motion of an Electron in Spinning Cosmic String Spacetime in the Presence of Uniform Magnetic Field and Aharonov-Bohm Potential

Sketch of the energy (Equation (71)) as a function of for , , , and different values of . In panel (a), , and in panel (b), . With the presence of Aharonov-Bohm flux, the energy of the state for a particular value of alpha is permissible for any value of . In the absence of Aharonov-Bohm flux, the energy of a state with a particular value of is nonpermissible for some values of (blue and red lines on panel (b)). For ever decreasing values, the antiparticle energy is more impacted. When approaches and the flux is zero, the modification in the energy levels is small (see the inset in panel (b)).
