Iterative Solutions for Low Lying Excited States of a Class of Schroedinger Equation

arXiv:quant-ph/0607075 · doi:10.1088/1009-1963/15/9/001

Abstract

The convergent iterative procedure for solving the groundstate Schroedinger equation is extended to derive the excitation energy and the wave function of the low-lying excited states. The method is applied to the one-dimensional quartic potential problem. The results show that the iterative solution converges rapidly when the coupling is not too small.
