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…

Predicting the Z-pinch Dimits shift through gyrokinetic tertiary instability analysis of the entropy mode
A. Hallenbert, G. G. Plunk
The Dimits shift, an upshift in the onset of turbulence from the linear instability threshold, caused by self-generated zonal flows, can greatly enhance the performance of magnetic…

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.…
