Quasi-linear theory of perpendicular ion heating by critically balanced turbulence
Zade Johnston, Jonathan Squire
In collisionless astrophysical plasmas, turbulence mediates the partitioning of free energy among cascade channels and its dissipation into ion and electron heat. The resulting ion…
A Unified Phenomenology of Ion Heating in Low- Plasmas: Test-Particle Simulations
Zade Johnston, Jonathan Squire, Romain Meyrand
We argue that stochastic and resonant ion heating, often viewed as distinct processes in low- collisionless plasmas, are the far limits of a continuum controlled by nonlinear br…
Pressure anisotropy and viscous heating in weakly collisional plasma turbulence
Jonathan Squire, Matthew W Kunz, Lev Arzamasskiy +3
Pressure anisotropy can strongly influence the dynamics of weakly collisional, high-beta plasmas, but its effects are missed by standard magnetohydrodynamics (MHD). Small changes t…
On the properties of Alfvénic switchbacks in the expanding solar wind: the influence of the Parker spiral
Jonathan Squire, Zade Johnston, Alfred Mallet +1
Switchbacks -- rapid, large deflections of the solar wind's magnetic field -- have generated significant interest as possible signatures of the key mechanisms that heat the corona…
On the properties of Alfvénic switchbacks in the expanding solar wind: three-dimensional numerical simulations
Zade Johnston, Jonathan Squire, Alfred Mallet +1
Switchbacks -- abrupt reversals of the magnetic field within the solar wind -- have been ubiquitously observed by Parker Solar Probe (PSP). Their origin, whether from processes nea…
