# Influence of tearing instability on magnetohydrodynamic turbulence

@article{Walker2018InfluenceOT, title={Influence of tearing instability on magnetohydrodynamic turbulence}, author={Justin Walker and Stanislav Boldyrev and Nuno F. Loureiro}, journal={Physical Review E}, year={2018} }

It has been proposed recently by Loureiro & Boldyrev (2017) and Mallet et al. (2017) that current sheets formed in the inertial range of magnetohydrodynamic turbulence become affected by the tearing instability at scales smaller than a critical scale $\lambda_\mathrm{c}$, larger than the dissipation scale of turbulence. If true, this process can modify the nature of energy cascade at smaller scales, leading to a new, tearing-mediated regime of MHD turbulence. In this Letter we present a…
