Semiclassical quantization by harmonic inversion: Comparison of algorithms- art. no. 056705

Harmonic inversion techniques have been shown to be a powerful toot for the semiclassical quantization and analysis of quantum spectra of both classic ally integrable and chaotic dynamical systems. Various computational proced ures have been proposed for this purpose. Our aim is to find out which meth od is numerically most efficient. To this end. we summarize and discuss the different techniques and compare their accuracies by way of two example sy stems.
