|Title:||Analytic expression for exact-ground-state energy based on an operator method for a class of anharmonic potentials||Authors:||Kwek, L.C.
|Issue Date:||Nov-2000||Citation:||Kwek, L.C., Liu, Y., Oh, C.H., Wang, X. (2000-11). Analytic expression for exact-ground-state energy based on an operator method for a class of anharmonic potentials. Physical Review A - Atomic, Molecular, and Optical Physics 62 (5) : 052107-052101. ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevA.62.052107||Abstract:||The full spectrum of a physical system is extracted with arbitrarily potentials using the shift operator method. The method is applied to a one-dimensional oscillator with anharmonic potentials. The supersymmetric quantum mechanics (SQM) is analyzed as a special case of a nonlinear algebraic operator method. Analytical results checked the accuracy of the state-dependent diagonalization.||Source Title:||Physical Review A - Atomic, Molecular, and Optical Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/95779||ISSN:||10502947||DOI:||10.1103/PhysRevA.62.052107|
