Abstract
A power moments based algebraic method that takes into account the local Taylor’s expansion structure of the wave function is applied to find the spectrum for the two dimensional paritytime symmetric potential Vx y = x 2 + y 2 + i g x 2 y Converging results are presented for a wide range of the strength parameter gCalculations for this work were performed with support from the High Performance Computing Center at Texas Southern University One of the authors DV is grateful for the support received from the National Science Foundation through grants for the Center for Research on Complex Networks HRD1137732 and Research Infrastructure for Science and Engineering RISE HRD1345173
