Viscosity and confinement in magnetized plasma
Robert W. Johnson
An alternative to the Braginskii decomposition is proposed, one rooted in treating the viscosity as a scalar quantity in a coordinate-free representation. With appropriate applicat…

Non-Newtonian viscosity in magnetized plasma
Robert W. Johnson
The particle and momentum balance equations can be solved on concentric circular flux surfaces to determine the effective viscous drag present in a magnetized tokamak plasma in the…

Glueballs in Flatland
Robert W. Johnson
The pure gauge theory in 2+1 dimensions is explored, through both a phenomenological model and a lattice calculation. The Isgur-Paton model is extended to include a curvature term…
