Non-Dynamic Alignment in Magnetohydrodynamic Turbulence
Amir Jafari
Dynamic alignment in MHD turbulence is commonly interpreted as a tendency of Elsässer increments to align toward smaller inertial-range scales. This interpretation is based on the…
Multi-Scale Coherence of Represented Flows
Amir Jafari
Many problems in nonlinear and statistical physics are formulated through represented flows, including physical-space vector fields, phase-space drift fields, and truncated renorma…
Statistical Flux Freezing with Magnetic Path-lines in Turbulence
Amir Jafari
Magnetic flux freezing states that, in ideal magnetohydrodynamics, magnetic flux is transported by the flow and magnetic field lines remain frozen into the plasma. In turbulent pla…
Effective Field Theories in Magnetohydrodynamics
Amir Jafari
We briefly review the recent developments in magnetohydrodynamics, which in particular deal with the evolution of magnetic fields in turbulent plasmas. We especially emphasize (i)…
Does Magnetic Reconnection Change Topology?
Amir Jafari
We employ well-known concepts from statistical physics, quantum field theories and general topology to study magnetic reconnection, topology-change and their connection in incompre…
