Second-order corrections to the non-commutative Klein-Gordon equation with a Coulomb potential (1101.0355v6)
Published 1 Jan 2011 in math-ph, hep-ph, hep-th, and math.MP
Abstract: We improve the previous study of the Klein-Gordon equation in a non-commutative space-time as applied to the Hydrogen atom to extract the energy levels, by considering the second-order corrections in the non-commutativity parameter. Phenomenologically we show that non-commutativity is the source of lamb shift corrections.
