    Landau Number to the Dirac Solution in Curved Space Time
    (Addis Ababa University, 2013-06) Tilahun, Negessa; Wetro, Legesse (PhD)
    In this paper we study the Landau number arising within the relativistic dynamics of a neutral particle which possesses a permanent magnetic dipole moment interacting with an external electric eld in the curved spacetime background. The eigenfunction and eigenvalues of the Hamiltonian are obtained. We show that the presence of the torsion eld breaks the in nite degeneracy of the Landau levels arising in this system
