Collisionless dynamo seeds from phase mixing-induced electron slippage
István Pusztai, Lise Hanebring, James Juno
Magnetic fields permeating the Universe on the largest astrophysical scales are thought to result from dynamo amplification in weakly collisional turbulence, but the origin of the…
From Weibel seeds to collisionless dynamos beyond pair-plasmas
Lise Hanebring, James Juno, Ammar Hakim +2
Bridging the spatiotemporal scales of magnetic seed field generation and subsequent dynamo amplification in the weakly collisional intracluster medium presents an extreme numerical…
Eulerian and Lagrangian electron energization during magnetic reconnection
Konrad Steinvall, Louis Richard, Tünde Fülöp +2
Electron energization by magnetic reconnection has historically been studied in the Lagrangian guiding-center framework. Insights from such studies include that Fermi acceleration…
Reduced modeling of scrape-off losses of runaway electrons during tokamak disruptions
Oskar Vallhagen, Lise Hanebring, Tünde Fülöp +2
Accurate modeling of runaway electron generation and losses during tokamak disruptions is crucial for the development of reactor-scale tokamak devices. In this paper we present a r…
