Ion sound instability driven by ion beam

O. Koshkarov, A. I. Smolyakov, I. D. Kaganovich +1

Ion sound instabilities driven by the ion flow in a system of a finite length are considered by analytical and numerical methods. The ion sound waves are modified by the presence o…

Instability-Enhanced Friction in the Presheath of Two-Ion-Species Plasmas

Scott D. Baalrud, Trevor Lafleur, William Fox +1

The speed at which ions enter a sheath is a fundamental property of a plasma that also provides a useful boundary condition in modeling. A recent theory proposed that this can be s…

Statistical simulation of the magnetorotational dynamo

Jonathan Squire, Amitava Bhattacharjee

Turbulence and dynamo induced by the magnetorotational instability (MRI) are analyzed using quasi-linear statistical simulation methods. It is found that homogenous turbulence is u…

Variational integration for ideal magnetohydrodynamics with built-in advection equations

Yao Zhou, Hong Qin, J. W. Burby +1

Newcomb's Lagrangian for ideal magnetohydrodynamics (MHD) in Lagrangian labeling is discretized using discrete exterior calculus. Variational integrators for ideal MHD are derived…

Rapid Change of Field Line Connectivity and Reconnection in Stochastic Magnetic Fields

Yi-Min Huang, A. Bhattacharjee, Allen H. Boozer

Magnetic fields without a direction of continuous symmetry have the generic feature that neighboring field lines exponentiate away from each other and become stochastic, hence the…

Magnetorotational instability: nonmodal growth and the relationship of global modes to the shearing box

Jonathan Squire, Amitava Bhattacharjee

We study the magnetorotational instability (MRI) using nonmodal stability techniques. Despite the spectral instability of many forms of the MRI, this proves to be a natural method…
