The Extension of the Massless Fermion Behaviour in the Cosmic String Spacetime

2020    Yeşiltaş, Özlem; Çağatay, Bengü; Aygün, Anıl L.

In this work, we have obtained the solutions of a massless fermion which is under the external magnetic field around a cosmic string for specific three potential models using supersymmetric quantum mechanics. The constant magnetic field, energy-dependent potentials, and position-dependent mass models are investigated for the Dirac Hamiltonians, and an extension of these three potential models and their solutions is also obtained. The energy spectrum and potential graphs for each case are discussed for the α deficit angle.
