A simple procedure for generating a Kappa distribution in PIC simulation

arXiv:2512.04272v1 Announce Type: new
Abstract: For kinetic modeling of plasma processes in space, a rejection-sampling procedure for generating a Kappa distribution in particle-in-cell (PIC) simulation is proposed. A Pareto distribution is employed as an envelope distribution. The procedure only requires uniform variates, and its acceptance efficiency is $approx 0.73$–$0.8$.
