Hot accretion flows contain collisionless plasmas that are believed to be capable of accelerating particles very high energies, as a result turbulence generated by the magnetorotational instability (MRI). We conduct unstratified shearing-box simulations MRI in ideal magnetohydrodynamic (MHD), and inject energetic (relativistic) test simulation snapshots detailed investigation on particle diffus...

Coupling Particle-Based Reaction-Diffusion Simulations with Reservoirs Mediated by PDEs

The motion of Brownian test particles in a model random potential with time dependent correlations is investigated using four methods: renormalized perturbation, perturbation using Martin, Siggia, and Rose functional formalism (MSR), the Edwards variational method on the MSR functional, and renormalization group with the MSR function. The disorder averaged one-particle propagators determined by...
