A Numerical Treatment of Energy Eigenvalues of Harmonic Oscillators Perturbed by a Rational Function
Philippe Gaudreau, Hassan Safouhi
In the present contribution, we apply the double exponential Sinc-collocation method (DESCM) to the one-dimensional time independent Schrödinger equation for a class of rational po…

On the Computation of Eigenvalues of the Anharmonic Coulombic Potential
Tyler Cassidy, Philippe Gaudreau, Hassan Safouhi
In this work, we propose a method combining the Sinc collocation method with the double exponential transformation for computing the eigenvalues of the anharmonic Coulombic potenti…
