Description
Conventional particle-in-cell methods for modeling plasma accelerators are prone to a variety of numerical instabilities and artifacts which can make them unreliable for long simulations. This is due to two issues: a lack of fidelity in the dispersion of the electromagnetic field update, and grid heating. We present a new class of algorithms, symplectic particle-in-mode (symPIM) algorithms, which are not subject to either of these artifacts. This makes symPIMs suitable for modeling long plasma stages with high fidelity.
