29 Nov 2004 | | Journal: | in Fundamental Physics Meeting "Alberto Galindo", R. F. Alvarez-Estrada, A. Dobado, L. A. Fernandez, M. A. Martin-Delgado, A. Munoz Sudupe (Eds.). Aula Documental de Investigacion, Madrid, 2004, pp. 253-261 | | Subject: | quant-ph | | Abstract: | A very simple procedure to calculate eigenenergies of quantum anharmonic oscillators is presented. The method, exact but for numerical computations, consists merely in requiring the vanishing of the Wronskian of two solutions which are regular respectively at the origin and at infinity. The first one can be represented by its series expansion; for the second one, an asymptotic expansion is available. The procedure is illustrated by application to quartic and sextic oscillators. | | Source: | arXiv, quant-ph/0411198 | | Services: | Forum | Review | PDF | Favorites | |
