Self-consistent Mean Field theory in weakly ionized media
Nicolas Leprovost, Eun-Jin Kim
We present a self-consistent mean field theory of the dynamo in 3D and turbulent diffusion in 2D in weakly ionized gas. We find that in 3D, the backreaction does not alter the beta…
Dynamics of Mesoscale Magnetic Field in Diffusive Shock Acceleration
P. H. Diamond, M. A. Malkov
We present a theory for the generation of mesoscale (, where is the cosmic ray gyroradius) magnetic fields during diffusive shock acceleration. The decay or mo…
On the gamma-ray spectra radiated by protons accelerated in SNR shocks near molecular clouds: The case of SNR RX J1713.7-3946
M. A. Malkov, P. H. Diamond, R. Z. Sagdeev
Cosmic rays (CRs) are thought to be accelerated in SNRs. The most favorable situation for proving that the main, hadronic CR component is accelerated there is when CRs interact wit…
Turbulent Diffusion of Magnetic Fields in Weakly Ionized Gas
Eun-jin Kim, P. H. Diamond
The diffusion of uni-directional magnetic fields by two dimensional turbulent flows in a weakly ionized gas is studied. The fields here are orthogonal to the plane of fluid motion.…
On the possible reason for non-detection of TeV-protons in SNRs
M. A. Malkov, P. H. Diamond, T. W. Jones
The theory of shock acceleration predicts the maximum particle energy to be limited only by the acceleration time and the size (geometry) of the shock. This led to optimistic estim…
Fast Zonal Field Dynamo in Collisionless Kinetic Alfven Wave Turbulence
I. Gruzinov, A. Das, P. H. Diamond
The possibility of fast dynamo action by collisionless kinetic Alfven Wave turbulence is demonstrated. The irreversibility necessary to lock in the generated field is provided by e…
