Enlarging the class of exactly solvable nonrelativistic problems
A. D. Alhaidari
We lift the constraint of a diagonal representation of the Hamiltonian by searching for square integrable bases that support a tridiagonal matrix representation of the wave operato…

On the relativistic two-point Green's function
A. D. Alhaidari
Using a recently developed approach for solving the three dimensional Dirac equation with spherical symmetry, we obtain simple representations for the Green's function of the Dirac…
