Numerical Treatment of Uehling-Ulenbeck Equations in Relativistic Plasma: Fast scheme with GPGPU Usage |
|
Abstract |
We propose a fast numerical scheme for Uehling-Ulenbeck equations, i.e. Boltzmann equations with inclusion of quantum degeneracy. The presented case treats isotropic mildly relativistic electron-positron-photon plasma including all two- and three-particle interactions (bremsstrahlung, double Compton scattering, etc.). The scheme, however, is much more general and can be applied to the wide class of systems with kinetic description. We propose a fast deterministic algorithm for multidimensional integration of collision integrals in such systems, that includes suitable angular reparametrization. |
