The Kraichnan Model and Non-Equilibrium Statistical Physics of Diffusive Mixing
Gregory Eyink, Amir Jafari
We discuss application of methods from the Kraichnan model of turbulent advection to the study of non-equilibrium concentration fluctuations arising during diffusion in liquid mixt…
Nanoflare Theory Revisited
Amir Jafari, Ethan Vishniac, Siyao Xu
Local magnetic reversals are an inseparable part of magnetohydrodynamic (MHD) turbulence whose collective outcome on an arbitrary scale in the inertial range may lead to a global s…
Power and spatial complexity in stochastic reconnection
Amir Jafari, Ethan Vishniac, Vignesh Vaikundaraman
The level of spatial complexity associated with a given vector field on an arbitrary range of scales \iffalse can be quantified by a simple, time-dependent function…
3D Turbulent Reconnection: Theory, Tests and Astrophysical Implications
Alex Lazarian, Gregory L. Eyink, Amir Jafari +4
Magnetic reconnection, topological change in magnetic fields, is a fundamental process in magnetized plasmas. It is associated with energy release in regions of magnetic field anni…
Carrier Density Oscillation in photoexcited Semiconductors
Ebrahim Najafi, Amir Jafari, Bolin Liao +1
The perturbation of a semiconductor from the thermodynamic equilibrium often leads to the display of nonlinear dynamics and formation of spatiotemporal patterns due to the spontane…
Magnetic topology in fluids
Amir Jafari, Ethan Vishniac
We study the evolution of turbulent magnetic fields from a topological point of view, invoking commonplace mathematical tools from general topology and dynamical systems theory whi…
