Hyperboloidal Method for Quasinormal Modes of Non-Relativistic Operators (dataset)

The Mathematica notebook (NRCH_Method.nb) used to implement a non-relativistic compactified hyperboloidal (NRCH) method for the QNMs of the Schrodinger equation. This also includes the Mathematica notebook (NRCH_Plots.nb) used to produce plots of the spectra for the perturbed and unperturbed Poschl-Teller potentials and the Mathematica notebook (NRCH_Dms_Generator.nb) used to calculate Chebyshev differentiation matrices for use in the method. Accompanying data includes samples (PP_Samples_013045500101059808370027304130857_.txt) of the potential perturbation considered, along with the calculated QNM frequencies for the unperturbed (spectral_data_ID_UNPERTURBED_N_201_P_101_.txt) and perturbed (spectral_data_ID_013045500101059808370027304130857_-30_N_201_P_101_.txt) Poschl-Teller potential.
