An explicit, energy-conserving particle-in-cell scheme for relativistic plasmas
Lee Ricketson, Jingwei Hu
We extend the recently-developed explicit, energy-conserving particle-in-cell (PIC) scheme of [1] to the relativistic Vlasov-Maxwell system. As in the non-relativistic case, the me…
Comment on "Impact of particle number and cell-size in fully implicit charge- and energy-conserving particle-in-cell schemes" by N. Savard et al., Phys. Plasmas 32, 073903 (2025)
Luis Chacon, Guangye Chen, Lee Ricketson
We take issue with the conclusions in the recent publication by Savard et al. In the study, the authors implement a fully nonlinear charge- and energy-conserving implicit particle-…
An Explicit Energy-Conserving Particle Method for the Vlasov-Fokker-Planck Equation
Jiyoung Yoo, Jingwei Hu, Lee F. Ricketson
We propose an explicit particle method for the Vlasov-Fokker-Planck equation that conserves energy at the fully discrete level. The method features two key components: a determinis…
A COGENT case study: Supporting Applications with Chombo
Daniel F. Martin, Milo Dorr, Mikhail Dorf +1
We present a case study of how a software framework (Chombo) supported the specific needs of a scientific application (COGENT). Since its inception in 2000, the Chombo framework ha…
An explicit, energy-conserving particle-in-cell scheme
Lee F. Ricketson, Jingwei Hu
We present an explicit temporal discretization of particle-in-cell schemes for the Vlasov equation that results in exact energy conservation when combined with an appropriate spati…
Asymptotic-preserving gyrokinetic implicit particle-orbit integrator for arbitrary electromagnetic fields
Lee Ricketson, Luis Chacón
We extend the asymptotic preserving and energy conserving time integrator for charged-particle motion developed in [Ricketson & Chacón, JCP, 2020] to include finite Larmor-radius (…
