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…
Bringing global gyrokinetic turbulence simulations to the transport timescale using a multiscale approach
Jeffrey B. Parker, Lynda L. LoDestro, Daniel Told +5
The vast separation dividing the characteristic times of energy confinement and turbulence in the core of toroidal plasmas makes first-principles prediction on long timescales extr…
Multilevel Monte Carlo simulation of Coulomb collisions
M. S. Rosin, L. F. Ricketson, A. M. Dimits +2
We present a new, for plasma physics, highly efficient multilevel Monte Carlo numerical method for simulating Coulomb collisions. The method separates and optimally minimizes the f…
