Energetic bounds on gyrokinetic instabilities. Part I: Fundamentals
P. Helander, G. G. Plunk
Upper bounds on the growth of free energy in gyrokinetics are derived. These bounds apply to all local gyrokinetic instabilities in the geometry of a flux tube, i.e. a slender volu…

Upper bounds on gyrokinetic instabilities
P. Helander, G. G. Plunk
A family of rigorous upper bounds on the growth rate of local gyrokinetic instabilities in magnetized plasmas is derived from the evolution equation for the Helmholtz free energy.…

Heat conduction in an irregular magnetic field: Part II. Heat transport as a measure of the effective non-integrable volume
Elizabeth J. Paul, Stuart R. Hudson, Per Helander
Given the large anisotropy of transport processes in magnetized plasmas, the magnetic field structure can strongly impact heat diffusion: magnetic surfaces and cantori form barrier…
