On the generation of astrophysically-relevant intermittent magnetic turbulence in the laboratory
Itamar Cohen, Weipeng Yao, Archie F. A. Bott +18
Intermittent magnetic turbulence, namely the presence of non-ordered and clusterized fields, is a ubiquitous phenomenon in space and astrophysical plasmas. It is currently understo…
Collisionless whistler heat-flux instability in ultra-high- plasmas
Rhisiart Davies, Prakriti Pal Choudhury, Archie F. A. Bott
Kinetic instabilities, notably the whistler heat-flux instability (WHFI), are known to suppress thermal transport significantly in the moderate- to high- plasmas relevant to man…
Efficient ion re-acceleration in laboratory-produced interpenetrating collisionless shocks
W. Yao, I. Cohen, P. Suarez Gerona +20
Although the origin of cosmic rays (CRs) remains an open question, collisionless magnetized shock waves are widely regarded as key sites for particle acceleration. Recent theories…
Modeling transport in weakly collisional plasmas using thermodynamic forcing
Prakriti Pal Choudhury, Archie F. A. Bott
How momentum, energy, and magnetic fields are transported in the presence of macroscopic gradients is a fundamental question in plasma physics. Answering this question is especiall…
Saturation of the compression of two interacting magnetic flux tubes evidenced in the laboratory
A. Sladkov, C. Fegan, W. Yao +16
Interactions between magnetic fields advected by matter play a fundamental role in the Universe at a diverse range of scales. A crucial role these interactions play is in making tu…
