Spectral estimates, stability conditions, and the rotating screw-pinch

Eliezer Hameiri

Research output: Contribution to journalArticlepeer-review


This article presents two sufficient conditions for the linear stability of rotating ideal plasmas, the first based on conservation of circulation and the second based on circle theorems applicable to linear Hamiltonian systems. The circle theorems also provide bounds on eigenmodes in the complex plane. All results are applied to the rotating screw-pinch which can be described by a single second-order ordinary differential equation.
