Is the Lowest Order Supersymmetric WKB Approximation Exact for All Shape Invariant Potentials ?
D. T. Barclay, Avinash Khare, U. Sukhatme
It has previously been proved that the lowest order supersymmetric WKB approximation reproduces the exact bound state spectrum of shape invariant potentials. We show that this is n…

New Eaxactly Solvable Hamiltonians: Shape Invariance and Self-Similarity
D. T. Barclay, R. Dutt, A. Gangopadhyaya +3
We discuss in some detail the self-similar potentials of Shabat and Spiridonov which are reflectionless and have an infinite number of bound states. We demonstrate that these self-…
