# Stability of plasmas through magnetic helicity

@inproceedings{Candelaresi2021StabilityOP, title={Stability of plasmas through magnetic helicity}, author={Simon Candelaresi and Fabio Del Sordo}, year={2021} }

Magnetic helicity, and more broadly magnetic field line topology, imposes constraints on the plasma dynamics. Helically interlocked magnetic rings are harder to bring into a topologically non-trivial state than two rings that are not linked. This particular restriction has the consequence that helical plasmas exhibit increased stability in laboratory devices, in the Sun and in the intergalactic medium. Here we discuss how a magnetic field is stabilizing the plasma and preventing it from…

The theory of plasma relaxation is described and developed. Turbulence, allied with a small resistivity, allows the plasma rapid access to a particular minimum-energy state. This process involves…

There is ample evidence of twisted magnetic structures in the solar corona. This motivates us to consider the magnetic twist as the cause of Alfven frequency continuum in the coronal loops, which can…

### Helicity balance and steady-state strength of the dynamo generated galactic magnetic field

- Physics
- 2000

It is demonstrated that the inclusion of the helicity flux in the magnetic helicity balance in the nonlinear stage of galac- tic dynamo action results in a radical change in the Magnetic field dynamics, which leads to sub- stantially subequipartition values for the equilibrium large-scale magnetic field.

Using mean-field models with a dynamical quenching formalism, we show that in finite domains magnetic helicity fluxes associated with small-scale magnetic fields are able to alleviate catastrophic…

It is conjecture that the existence of an additional topological invariant in any flux tube with a nonzero field: the topological degree of the field line mapping constrains the relaxation, explaining why only one of three example simulations reaches the Taylor state.
