An Example of Poincare Symmetry with a Central Charge
E. Karat
We discuss a simple system which has a central charge in its Poincare algebra. We show that this system is exactly solvable after quantization and that the algebra holds without an…

Self-Adjoint Extensions of the Pauli Equation in the Presence of a Magnetic Monopole
Edwin R. Karat, Michael B. Schulz
We discuss the Hamiltonian for a nonrelativistic electron with spin in the presence of an abelian magnetic monopole and note that it is not self-adjoint in the lowest two angular m…
