Equipartition between Alfvénic turbulence and energetic ions as the origin of the -5 common spectrum in the heliosphere
Stanislav Boldyrev, Daniel Humphrey, Vadim Roytershteyn
Suprathermal ion tails throughout the heliosphere follow a ``common spectrum,'' . We show that scale-by-scale equipartition between strong Alfvénic turbulence a…

Particle acceleration in Alfvénic turbulence with a strong guide field
Daniel Humphrey, Stanislav Boldyrev, Vadim Roytershteyn
Magnetically dominated Alfvénic turbulence creates an effective environment for particle acceleration. However, when a strong mean field is present, traditional mechanisms like mir…

Distributions of particles accelerated by strong Alfvénic turbulence
Stanislav Boldyrev, Daniel Humphrey, Vadim Roytershteyn +1
This work presents a model for generating nonthermal power-law tails of particles' energy probability density functions in turbulent collisionless plasmas, applicable to both non-r…
