Noncommutative Quantum Mechanics from Noncommutative Quantum Field Theory

arXiv:hep-th/0110191 · doi:10.1103/PhysRevLett.88.151602

Abstract

We derive noncommutative multi-particle quantum mechanics from noncommutative quantum field theory in the nonrelativistic limit. Paricles of opposite charges are found to have opposite noncommutativity. As a result, there is no noncommutative correction to the hydrogen atom spectrum at the tree level. We also comment on the obstacles to take noncommutative phenomenology seriously, and propose a way to construct noncommutative SU(5) grand unified theory.
