Kinetic-j: A computational kernel for solving the linearized Vlasov equation applied to calculations of the kinetic, configuration space plasma current for time harmonic wave electric fields

We present the Kinetic-j code, a computational kernel for evaluating the linearized Vlasov equation with application to calculating the kinetic plasma response (current) to an applied time harmonic wave electric field. This code addresses the need for a configuration space evaluation of the plasma current to enable kinetic full-wave solvers for waves in hot plasmas to move beyond the limitations of the traditional Fourier spectral methods. We benchmark the kernel via comparison with the standard k-space forms of the hot plasma conductivity tensor.

本报告推出 Kinetic-j 代码，该代码为一计算内核，旨在评估线性化 Vlasov 方程，并应用于计算受时间谐波电场作用的动性等离子体响应（电流）。该代码旨在满足对等离子体电流配置空间评估的需求，从而使得针对高温等离子体中波动的动力学全波求解器能够突破传统傅里叶频谱方法所受的限制。我们通过将内核与标准 k 空间形式的热等离子体电导率张量进行对比，对内核进行了基准测试。
