Modifications to Swisdak (2013)'s rejection sampling algorithm for a Maxwell–Jüttner distribution in particle simulations

Modifications to Swisdak's [Phys. Plasmas 20, 062110 (2013)] rejection sampling algorithm for drawing a Maxwell–Jüttner 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.

期刊介绍： Physics of Plasmas (PoP), published by AIP Publishing in cooperation with the APS Division of Plasma Physics, is committed to the publication of original research in all areas of experimental and theoretical plasma physics. PoP publishes comprehensive and in-depth review manuscripts covering important areas of study and Special Topics highlighting new and cutting-edge developments in plasma physics. Every year a special issue publishes the invited and review papers from the most recent meeting of the APS Division of Plasma Physics. PoP covers a broad range of important research in this dynamic field, including: -Basic plasma phenomena, waves, instabilities -Nonlinear phenomena, turbulence, transport -Magnetically confined plasmas, heating, confinement -Inertially confined plasmas, high-energy density plasma science, warm dense matter -Ionospheric, solar-system, and astrophysical plasmas -Lasers, particle beams, accelerators, radiation generation -Radiation emission, absorption, and transport -Low-temperature plasmas, plasma applications, plasma sources, sheaths -Dusty plasmas
