Modifications to Swisdak (2013)'s rejection sampling algorithm for a Maxwell-Jüttner distribution in particle simulations (2408.09105v2)
Published 17 Aug 2024 in physics.plasm-ph, astro-ph.HE, and physics.comp-ph
Abstract: Modifications to Swisdak [Phys. Plasmas 20, 062110 (2013)]'s rejection sampling algorithm for drawing a Maxwell-J\"{u}ttner distribution in particle simulations are presented. Handy approximations for $e$-folding points and a linear slope in the envelope function are proposed, to make the algorithm self-contained and more efficient.
