Velocity space origins of pressure-strain interaction in multi-population distributions and its application to magnetic reconnection
M. Hasan Barbhuiya, Paul A. Cassak, Sarah Conley +7
A forefront research question is how energy evolves in weakly collisional plasmas for which departures from local thermodynamic equilibrium (LTE) are significant. The standard appr…
Effects of Unequal Electron-Ion Plasma Beta on Pressure-Strain Interaction in Turbulent Plasmas
M. Hasan Barbhuiya, Subash Adhikari
A common occurrence in weakly collisional space plasmas is the unequal electron-ion temperatures. The pressure-strain interaction provides a mechanism-agnostic pathway for increasi…
Kinetic Scale Energy Budget in Turbulent Plasmas: Role of Electron to Ion Temperature Ratio
Subash Adhikari, M. Hasan Barbhuiya
The dissipation mechanisms in weakly collisional plasmas have been a longstanding topic of investigation, where significant progress has been made in recent years. A recent promisi…
Identifying the Growth Phase of Magnetic Reconnection using Pressure-Strain Interaction
M. Hasan Barbhuiya, Paul A. Cassak, Alex Chasapis +3
Magnetic reconnection often initiates abruptly and then rapidly progresses to a nonlinear quasi-steady state. While satellites frequently detect reconnection events, ascertaining w…
A Magnetic Analog of Pressure-Strain Interaction
M. Hasan Barbhuiya, P. A. Cassak
We study the evolution equation for magnetic energy density for a non-relativistic magnetized plasma in the (Lagrangian) reference frame comoving with the electron bulk velocity. A…
The Kinetic Analogue of the Pressure-Strain Interaction
Sarah A. Conley, James Juno, Jason M. TenBarge +4
Energy transport in weakly collisional plasma systems is often studied with fluid models and diagnostics. However, the applicability of fluid models is necessarily limited when col…
Higher-order nonequilibrium term: Effective power density quantifying evolution towards or away from local thermodynamic equilibrium
M. Hasan Barbhuiya, Paul A. Cassak, Subash Adhikari +3
A common approach to assess the nature of energy conversion in a classical fluid or plasma is to compare power densities of the various possible energy conversion mechanisms. A for…
The Importance of Heat Flux in Quasi-Parallel Collisionless Shocks
Colby C. Haggerty, Damiano Caprioli, Paul A. Cassak +3
Collisionless plasma shocks are a common feature of many space and astrophysical systems and are sources of high-energy particles and non-thermal emission, channeling as much as 20…
Quantifying Energy Conversion in Higher Order Phase Space Density Moments in Plasmas
Paul A. Cassak, M. Hasan Barbhuiya, Haoming Liang +1
Weakly collisional and collisionless plasmas are typically far from local thermodynamic equilibrium (LTE), and understanding energy conversion in such systems is a forefront resear…
Pressure-Strain Interaction: II. Decomposition in Magnetic Field-Aligned Coordinates
Paul A. Cassak, M. Hasan Barbhuiya, H. Arthur Weldon
In weakly collisional and collisionless magnetized plasmas, the pressure-strain interaction describes the rate of conversion between bulk flow and thermal energy density. In this s…
Pressure-Strain Interaction: I. On Compression, Deformation, and Implications For Pi-D
Paul A. Cassak, M. Hasan Barbhuiya
The pressure-strain interaction describes the rate per unit volume that energy is converted between bulk flow and thermal energy in neutral fluids or plasmas. The term has been wri…
Pressure-Strain Interaction: III. Particle-in-Cell Simulations of Magnetic Reconnection
M. Hasan Barbhuiya, Paul A. Cassak
How energy is converted into thermal energy in weakly collisional and collisionless plasma processes such as magnetic reconnection and plasma turbulence has recently been the subje…
Scaling of electron heating by magnetization during reconnection and applications to dipolarization fronts and super-hot solar flares
M. Hasan Barbhuiya, Paul. A. Cassak, Michael. A. Shay +5
Electron ring velocity space distributions have previously been seen in numerical simulations of magnetic reconnection exhausts and have been suggested to be caused by the magnetiz…
Kinetic Entropy-Based Measures of Distribution Function Non-Maxwellianity: Theory and Simulations
Haoming Liang, M. Hasan Barbhuiya, P. A. Cassak +4
We investigate kinetic entropy-based measures of the non-Maxwellianity of distribution functions in plasmas, i.e., entropy-based measures of the departure of a local distribution f…
