Finite Dissipation in Anisotropic Magnetohydrodynamic Turbulence
Riddhi Bandyopadhyay, S. Oughton, M. Wan +3
In presence of an externally supported, mean magnetic field a turbulent, conducting medium, such as plasma, becomes anisotropic. This mean magnetic field, which is separate from th…
Scale dependence of energy transfer in turbulent plasma
Yan Yang, Minping Wan, William H. Matthaeus +5
In the context of space and astrophysical plasma turbulence and particle heating, several vocabularies emerge for estimating turbulent energy dissipation rate, including Kolmogorov…
Kinetic range spectral features of cross-helicity using MMS
Tulasi N. Parashar, Alexandros Chasapis, Riddhi Bandyopadhyay +13
We study spectral features of ion velocity and magnetic field correlations in the solar wind and in the magnetosheath using data from the Magnetospheric Multi-Scale (MMS) spacecraf…
Turbulent electromagnetic fields at sub-proton scales: two-fluid and full-kinetic plasma simulations
C. A. González, T. Parashar, D. Gomez +2
Plasma dynamics is a multi-scale problem that involves many spatial and temporal scales. Turbulence connects the disparate scales in this system through a cascade that is establish…
Dependence of Kinetic Plasma Turbulence on Plasma beta
Tulasi N. Parashar, William H. Matthaeus, Michael A Shay
We study the effects of plasma \b{eta} (ratio of plasma pressure to magnetic pressure) on the evolution of kinetic plasma turbulence using fully kinetic particle-in-cell simulation…
Solar Wind Turbulence Studies using MMS Fast Plasma Investigation Data
Riddhi Bandyopadhyay, A. Chasapis, R. Chhiber +17
Studies of solar wind turbulence traditionally employ high-resolution magnetic field data, but high-resolution measurements of ion and electron moments have been possible only rece…
Incompressive Energy Transfer in the Earth's Magnetosheath: Magnetospheric Multiscale Observations
Riddhi Bandyopadhyay, A. Chasapis, R. Chhiber +14
Using observational data from the \emph{Magnetospheric Multiscale} (MMS) Mission in the Earth's magnetosheath, we estimate the energy cascade rate using different techniques within…
Single-mode nonlinear Langevin emulation of magnetohydrodynamic turbulence
Riddhi Bandyopadhyay, William H. Matthaeus, Tulasi N. Parashar
Based on the Langevin equation of Brownian motion, we present a simple model that emulates a typical mode in incompressible magnetohydrodynamic turbulence, providing a demonstratio…
