Gauge invariant hydrogen atom Hamiltonian
For quantum mechanics of a charged particle in a classical external electromagnetic field, there is an apparent puzzle that the matrix element of the canonical momentum and Hamiltonian operators is gauge dependent. A resolution to this puzzle is recently

WKB-approach for the 1D hydrogen atom
Taking into account results of WKB-approximation, we derive exact quantum energies and wave functions of even and odd states in the one-dimensional Coulomb potential V(x)=-1/x,-∞

Weber’s electrodynamics for the hydrogen atom
The original Weber action at a distance theory is valid for slowly varying effects, and it in addition to predicting all of the usual electrodynamical results, leads to crucial effects where the Maxwell theory fails.

Exact Solution of the Klein-Gordon Equation for the Hydrogen Atom Including Electron Spin [PDF]
The term describing the coupling between total angular momentum and energy-momentum in the hydrogen atom is isolated from the radial Dirac equation and used to replace the corresponding orbital angular momentum coupling term in the radial K-G equation ...
