Numerical computation of resonance poles in scattering theory.
We present a possible way of computing resonance poles and modes in scattering theory. Numerical examples are given for the scattering of electromagnetic waves by finite-size photonic crystals.
متن کاملNumerical computation of isotropic Compton scattering
Context. Compton scattering is involved in many astrophysical situations. It is well known and has been studied in detail for the past fifty years. Exact formulae for the different cross sections are often complex, and essentially asymptotic expressions have been used in the past. Numerical capabilities have now developed to a point where they enable the direct use of exact formulae in sophisti...

متن کاملThreshold behaviour of scattering poles
The results of a model for meson-meson scattering are studied. The model is shown to be capable of on the one hand reproducing the scattering data, while on the other hand a quark-antiquark confinement spectrum can be determined. It is concluded that adopting the model’s formulation of the transition matrix elements for data analysis , it may serve as a link between experiment and quenched latt...
