Boris and Exponential Integrators in the Theory of Particles Interacting with Magnetic Turbulence
Andreas Shalchi
The interaction of electrically charged particles with magnetic fields is a fundamental problem in several areas of physics. An example is the motion of energetic particles through…
Parallel and perpendicular diffusion of energetic particles in the near-Sun solar wind observed by Parker Solar Probe
Nibuna Siranjeevi Madam Subashchandar, Lingling Zhao, Andreas Shalchi +6
We investigate energetic particle diffusion in the inner heliosphere (approximately 0.06-0.3 AU) explored by Parker Solar Probe (PSP). Parallel (kappa_parallel) and perpendicular (…
Subspace Approximation to the Focused Transport Equation. II. The Modified Form
B. Klippenstein, A. Shalchi
The transport of energetic particles in a spatially varying magnetic field is described by the focused transport equation. In the past two versions of this equation were investigat…
Solar Coronal Heating: Role of Kinetic and Inertial Alfvén Waves in Heating and Charged Particle Acceleration
Syed Ayaz, Gary P. Zank, Imran A. Khan +3
A comprehensive understanding of solar coronal heating and charged particle acceleration remains one of the most critical challenges in space and astrophysical plasma physics. In t…
Subspace Approximations to the Focused Transport Equation of Energetic Particles, I. The Standard Form
B. Klippenstein, A. Shalchi
The Fokker-Planck equation describing the transport of energetic particles interacting with turbulence is difficult to solve analytically. Numerical solutions are of course possibl…
