Estimation of Effective Viscosity to Quantify Collisional Behavior in Collisionless Plasma
Subash Adhikari, Carlos Gonzalez, Yan Yang +4
While dissipation in collisional plasma is defined in terms of viscosity and resistivity, the exact functional form of dissipation i.e., the so-called dissipation function in nearl…
Revisiting compressible and incompressible pressure-strain interaction in kinetic plasma turbulence
Subash Adhikari, Yan Yang, William H. Matthaeus
In this study, we revisit the pressure-strain interaction in kinetic turbulence, and in particular we re-examine the decomposition of pressure-strain interaction into compressive a…
Scale Filtering Analysis of Kinetic Reconnection and its Associated Turbulence
Subash Adhikari, Yan Yang, William H. Matthaeus +3
Previously, using an incompressible von Kármán-Howarth formalism, the behavior of cross-scale energy transfer in magnetic reconnection and turbulence was found to be essentially id…
Statistics of Pressure Fluctuations in Turbulent Kinetic Plasmas
Subash Adhikari, William H. Matthaeus, Tulasi N. Parashar +2
In this study we explore the statistics of pressure fluctuations in kinetic collisionless turbulence. A 2.5D kinetic particle-in-cell (PIC) simulation of decaying turbulence is use…
Effect of a guide field on the turbulence like properties of magnetic reconnection
Subash Adhikari, Michael A. Shay, Tulasi N. Parashar +4
The effect of an external guide field on the turbulence-like properties of magnetic reconnection is studied using five different 2.5D kinetic particle-in-cell (PIC) simulations. Th…
Magnetic reconnection as an energy cascade process
S. Adhikari, T. N. Parashar, M. A. Shay +5
Reconnection and turbulence are two of the most commonly observed dynamical processes in plasmas, but their relationship is still not fully understood. Using 2.5D kinetic particle-…
