Irreducible Three-Loop Vacuum-Polarization Correction in Muonic Bound Systems
G. S. Adkins, U. D. Jentschura
Three-loop electronic vacuum-polarization corrections due to irreducible diagrams are evaluated for two-body muonic ions with nuclear charge numbers 1 <= Z <= 6. The corrections ar…
Relativistic and Recoil Corrections to Vacuum polarization in muonic systems: Three--photon exchange, gauge invariance and numerical values
Gregory S. Adkins, Ulrich D. Jentschura
For an accurate theoretical description of muonic bound systems, it is crucial to consistently treat relativistic and recoil corrections to vacuum polarization. The one-loop vacuum…
Recoil corrections to the energy levels of hydrogenic atoms
Gregory S. Adkins, Jonathan Gomprecht, Yanxi Li +1
We have completed the calculation of pure-recoil corrections of order to Coulombic bound states of two spin-1/2 fermions without approximation in the particle masses. Our…
Coulomb expectation values in and dimensions
Gregory S. Adkins, Md Faisal Alam, Conor Larison +1
We explore the quantum Coulomb problem for two-body bound states, in and dimensions, in detail, and give an extensive list of expectation values that arise in the ev…
The hydrogen atom in dimensions
Gregory S. Adkins
The nonrelativistic hydrogen atom in dimensions is the reference system for perturbative schemes used in dimensionally regularized nonrelativistic effective field theories…
Angular decomposition of tensor products of a vector
Gregory S. Adkins
The tensor product of copies of a single vector, such as , can be analyzed in terms of angular momentum. When is decomposed into a su…
