We develop a quantitative relationship between magnetic diffusion and the level of randomness, or stochasticity, of the diffusing magnetic field in a magnetized medium. A general mathematical formulation of magnetic stochasticity in turbulence has been developed in previous work in terms of the L_{p} norm S_{p}(t)=1/2∥1-B[over ̂]_{l}·B[over ̂]_{L}∥_{p}, pth-order magnetic stochasticity of the stochastic field B(x,t), based on the coarse-grained fields B_{l} and B_{L} at different scales l≠L…

Statistical analysis of stochastic magnetic fields.
TLDR
Theoretical predictions of the theoretically predicted global relationship between stochasticity and cross energy is observed in different subvolumes of the simulation box and indicate ubiquitous local field-fluid slippage and reconnection events in MHD turbulence.
3D turbulent reconnection: Theory, tests, and astrophysical implications
Magnetic reconnection, topological changes in magnetic fields, is a fundamental process in magnetized plasmas. It is associated with energy release in regions of magnetic field annihilation, but this
Fast nuclear spin relaxation rates in tilted cone Weyl semimetals: redshift factors from Korringa relation
TLDR
It is demonstrated that such a strong enhancement for ζ ≲ 1 that gives rise to very fast relaxation rates, is contributed by a new hyperfine interactions arising from the tilt itself.

Power and complexity in stochastic reconnection
The level of spatial complexity associated with a given vector field on an arbitrary range of scales \iffalse ${\bf F(x}, t)$ can be quantified by a simple, time-dependent function $S(t)={1\over
Turbulent drag reduction in magnetohydrodynamic and quasi-static magnetohydrodynamic turbulence
In hydrodynamic turbulence, the kinetic energy injected at large scales cascades to the inertial range, leading to a constant kinetic energy flux. In contrast, in magnetohydrodynamic (MHD)

Topology and stochasticity of turbulent magnetic fields.
TLDR
The results support the well-founded yet partly overlooked picture in which magnetic reconnection in turbulent fluids occurs on a wide range of scales as a result of nonlinearities at large scales (turbulence inertial range) and nonidealities at small scales (dissipative range).

TLDR
An important application of these results is the kinematic, fluctuation dynamo in nonhelical, incompressible turbulence at magnetic Prandtl number (Pr(m)) equal to unity, which demonstrates a strong similarity between the Pr(m)=1 and 0 dynamos.
Generalized flows, intrinsic stochasticity, and turbulent transport
The study of passive scalar transport in a turbulent velocity field leads naturally to the notion of generalized flows, which are families of probability distributions on the space of solutions to
Reconnection in a weakly stochastic field
We examine the effect of weak, small-scale magnetic field structure on the rate of reconnection in a strongly magnetized plasma. This affects the rate of reconnection by reducing the transverse scale
Flux-freezing breakdown in high-conductivity magnetohydrodynamic turbulence
TLDR
An analysis of a simulation of magnetohydrodynamic turbulence at high conductivity that exhibits Richardson dispersion, which leads to line motions that are completely indeterministic or ‘spontaneously stochastic’, as predicted in analytical studies.
TURBULENT GENERAL MAGNETIC RECONNECTION
Plasma flows with an MHD-like turbulent inertial range, such as the solar wind, require a generalization of General Magnetic Reconnection (GMR) theory. We introduce the slip-velocity source vector,
Magnetohydrodynamic Turbulence Revisited
In 1965, Kraichnan proposed that MHD turbulence occurs as a result of collisions between oppositely directed Alfven wave packets. Recent work has generated some controversy over the nature of
Stochastic Reconnection for Large Magnetic Prandtl Numbers
We consider stochastic magnetic reconnection in high-β plasmas with large magnetic Prandtl numbers, Pr m > 1. For large Pr m , field line stochasticity is suppressed at very small scales, impeding
