Novel quasi-exactly solvable models with anharmonic singular potentials

arXiv:1201.3427 · doi:10.1016/j.aop.2012.11.013

Abstract

We present new quasi-exactly solvable models with inverse quartic, sextic, octic and decatic power potentials, respectively. We solve these models exactly via the functional Bethe ansatz method. For each case, we give closed-form solutions for the energies and the wave functions as well as analytical expressions for the allowed potential parameters in terms of a set of algebraic equations.
