We explore the quantum Coulomb problem for two-body bound states, in $D=3$ and $D=3\ensuremath{-}2\ensuremath{\epsilon}$ dimensions, in detail, and give an extensive list of expectation values that arise in the evaluation of QED corrections to bound-state energies. We describe the techniques used to obtain these expectation values and give general formulas for the evaluation of integrals involving associated Laguerre polynomials. In addition, we give formulas for the evaluation of integrals…

Multidimensional hydrogenic states: position and momentum expectation values
The position and momentum probability densities of a multidimensional quantum system are fully characterized by means of the radial expectation values ⟨r α ⟩ and pα , respectively. These quantities,
Calculation of higher order corrections to positronium energy levels
We report on progress in the calculation of corrections to positronium energy levels of order m α 7 . Corrections at this level will be needed for the interpretation of the results of upcoming

We search for first- and second-order corrections to the energy levels of the Pauli–Dirac equation within the Rayleigh–Schrödinger theory. We use some identities satisfied by the associated Laguerre
