Algebraic approach and coherent states for a relativistic quantum particle in cosmic string spacetime
M. Salazar-Ramírez, D. Ojeda-Guillén, R. D. Mota
We study a relativistic quantum particle in cosmic string spacetime in the presence of a uniform magnetic field and a Coulomb-type scalar potential. It is shown that the radial par…
