On extreme points of the diffusion polytope
M. J. Hay, J. Schiff, N. J. Fisch
We consider a class of diffusion problems defined on simple graphs in which the populations at any two vertices may be averaged if they are connected by an edge. The diffusion poly…

Ignition threshold for non-Maxwellian plasmas
Michael J. Hay, Nathaniel J. Fisch
An optically thin -B plasma loses more energy to bremsstrahlung than it gains from fusion reactions, unless the ion temperature can be elevated above the electron tempera…

Maximal energy extraction under discrete diffusive exchange
Michael J. Hay, Jeremy Schiff, Nathaniel J. Fisch
Waves propagating through a bounded plasma can rearrange the densities of states in the six-dimensional velocity-configuration phase space. Depending on the rearrangement, the wave…
