FFT-based free space Poisson solvers: why Vico-Greengard-Ferrando should replace Hockney-Eastwood
Junyi Zou, Eugenia Kim, Antoine J. Cerfon
Many problems in beam physics and plasma physics require the solution of Poisson's equation with free-space boundary conditions. The algorithm proposed by Hockney and Eastwood is a…
Dimits shift, avalanche-like bursts, and Solitary propagating structures in the two-field Flux-Balanced Hasegawa-Wakatani model for plasma edge turbulence
Di Qi, Andrew J. Majda, Antoine J. Cerfon
We show that the recently introduced two-field flux-balanced Hasegawa-Wakatani (BHW) model captures the key features of drift-wave turbulent transport mediated by zonal flows obser…
A Flux-Balanced Fluid Model for Collisional Plasma Edge Turbulence: Numerical Simulations with Different Aspect Ratios
Di Qi, Andrew J. Majda, Antoine J. Cerfon
We investigate the drift wave -- zonal flow dynamics in a shearless slab geometry with the new flux-balanced Hasegawa-Wakatani model. As in previous Hasegawa-Wakatani models, we ob…
A Flux-Balanced Fluid Model for Collisional Plasma Edge Turbulence: Model Derivation and Basic Physical Features
Andrew J. Majda, Di Qi, Antoine J. Cerfon
We propose a new reduced fluid model for the study of the drift wave -- zonal flow dynamics in magnetically confined plasmas. Our model can be viewed as an extension of the classic…
Fast and spectrally accurate evaluation of gyroaverages in non-periodic gyrokinetic-Poisson simulations
Joseph Guadagni, Antoine J. Cerfon
We present a fast and spectrally accurate numerical scheme for the evaluation of the gyroaveraged electrostatic potential in non-periodic gyrokinetic-Poisson simulations. Our metho…
