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…

Idealized Global Models of Accretion Disks with Strong Toroidal Magnetic Fields
Minghao Guo, Eliot Quataert, Jonathan Squire +2
We present global magnetohydrodynamic (MHD) simulations of idealized accretion disks with a strong toroidal magnetic field using an equation of state that fixes the gas thermal sca…

Thermodynamics and collisionality in firehose-susceptible high- plasmas
A. F. A. Bott, M. W. Kunz, E. Quataert +2
We study the evolution of collisionless plasmas that, due to their macroscopic evolution, are susceptible to the firehose instability, using both analytic theory and hybrid-kinetic…
