Higher order intertwining approach to quasinormal modes

arXiv:0705.3304 · doi:10.1088/1751-8113/40/22/007

Abstract

Using higher order intertwining operators we obtain new exactly solvable potentials admitting quasinormal mode (QNMs) solutions of the Klein-Gordon equation. It is also shown that different potentials exhibiting QNMs can be related through nonlinear supersymmetry.
