Public opinion about solar radiation management: A cross-cultural study in 20 c...
Contzen, N.; Perlaviciute, G.; Steg, L.; Reckels, S. C.; Alves, S.; Bidwell, D.; Böhm, G.; Bonaiuto, M.; Chou, L.-F.; Corral-Verdugo, V.; Dessi, F.Some argue that complementing climate change mitigation measures with solar radiation management (SRM) might prove a last resort to limit global warming to 1.5 °C. To make a socially responsible decision on whether to use SRM, it is important to consider also public opinion, across the globe and particularly in the Global South, which would face the greatest risks from both global warming and SRM. However, most...
A new field solver for modeling of relativistic particle-laser interactions usi...
Li, F.; Miller, K. G.; Xu, X.; Tsung, F. S.; Decyk, V. K.; An, W.; Fonseca, R. A.; Mori, W. B.A customized finite-difference field solver for the particle-in-cell (PIC) algorithm that provides higher fidelity for wave-particle interactions in intense electromagnetic waves is presented. In many problems of interest, particles with relativistic energies interact with intense electromagnetic fields that have phase velocities near the speed of light. Numerical errors can arise due to (1) dispersion errors i...

Controlling the numerical Cerenkov instability in PIC simulations using a custo...
Li, F.; Yu, P. C.; Xu, X.; Fiuza, F.; Decyk, V. K.; Dalichaouch, T.; Davidson, A.; Tableman, A.; An, W.; Tsung, F. S.; Fonseca, R. A.; Lu, W.In this paper we present a customized finite-difference-time-domain (FDTD) Maxwell solver for the particle-in-cell (PIC) algorithm. The solver is customized to effectively eliminate the numerical Cerenkov instability (NCI) which arises when a plasma (neutral or non-neutral) relativistically drifts on a grid when using the PIC algorithm. We control the EM dispersion curve in the direction of the plasma drift of ...
Enabling Lorentz boosted frame particle-in-cell simulations of laser wakefield ...
Yu, P.; Xu, X.; Davidson, A.; Tableman, A.; Dalichaouch, T.; Li, F.; Meyers, M. D.; An, W.; Tsung, F. S.; Decyk, V. K.; Fiuza, F.; Vieira, J.When modeling laser wakefield acceleration (LWFA) using the particle-in-cell (PIC) algorithm in a Lorentz boosted frame, the plasma is drifting relativistically at beta(b)c towards the laser, which can lead to a computational speedup of similar to gamma(2)(b)=(1-beta(2)(b))-1. Meanwhile, when LWFA is modeled in the quasi-3D geometry in which the electromagnetic fields and current are decomposed into a limited n...
