Study of anharmonic singular potentials

Nasser Saad, Richard L. Hall, Qutaibeh D. Katatbeh

A simple and efficient variational method is introduced to accelerate the convergence of the eigenenergy computations for a Hamiltonian H with singular potentials. Closed-form anal…

A basis for variational calculations in d dimensions

Richard L. Hall, Qutaibeh D. Katatbeh, Nasser Saad

In this paper we derive expressions for matrix elements (ϕ_i,Hϕ_j) for the Hamiltonian H=-Δ+\sum_q a(q)r^q in d > 1 dimensions. The basis functions in each angular momentum subspac…
