Semiclassical anomalies of the quantum mechanical systems and their modifications for the asymptotic matching

Abstract

Abstract JWKB solutions to the Initial Value Problems (IVPs) of the Time Independent Schrodinger’s Equation (TISE) for the Simple Linear Potentials (SLPs) with a turning point parameter have been studied according to the turning points by graphical analysis to test the results of the JWKB solutions and suggested modifications. The anomalies happening in the classically inaccessible region where the SLP function is smaller than zero and the results of the suggested modifications, which are in consistent with the quantum mechanical theories, to remove these anomalies in this region have been presented. The origins of the anomalies and verifications of the suggested modifications showing a great success in the results have also been studied in terms of a suggested M ij = S ∼ i - 1 , j matrix elements made up of the JWKB expansion terms, Si−1,j (where i = 1, 2, 3 and j = 1, 2). The results of the modifications for the IVPs and their application to the Bound State Problems (BSPs) with an example application of the Harmonic Oscillator (HO) have been presented and their generalization for any potential function have been discussed and classified accordingly.
