Kinetic plasma turbulence cascade spans multiple scales ranging from macroscopic fluid flow to sub-electron scales. Mechanisms that dissipate large scale energy, terminate the inertial range cascade and convert kinetic energy into heat are hotly debated. Here we revisit these puzzles using fully kinetic simulation. By performing scale-dependent spatial filtering on the Vlasov equation, we extract information at prescribed scales and introduce several energy transfer functions. This approach… 

Pressure–Strain Interaction as the Energy Dissipation Estimate in Collisionless Plasma

The dissipative mechanism in weakly collisional plasma is a topic that pervades decades of studies without a consensus solution. We compare several energy dissipation estimates based on energy

Pathways to Dissipation in Weakly Collisional Plasmas

Observed turbulence in space and astrophysics is expected to involve cascade and subsequent dissipation and heating. Contrary to standard collisional fluid turbulence, the weakly collisional

Free Energy Sources in Current Sheets Formed in Collisionless Plasma Turbulence

Collisionless dissipation of macroscopic energy into heat is an unsolved problem of space and astrophysical plasmas, e.g., solar wind and Earth’s magnetosheath. The most viable process under

The process of conversion or dissipation of energy in nearly collisionless turbulent space plasma is yet to be fully understood. The existing models offer different energy dissipation mechanisms

Cascades and Dissipative Anomalies in Nearly Collisionless Plasma Turbulence

We develop first-principles theory of kinetic plasma turbulence governed by the Vlasov-Maxwell-Landau equations in the limit of vanishing collision rates. Following an exact renormalization-group

Coherent Structures and Spectral Energy Transfer in Turbulent Plasma: A Space-Filter Approach.

A strong relationship between scale-to-scale energy transfer and coherent structures is demonstrated and the inhomogeneity of the turbulence cascade induced by topological structures in the magnetic field is quantified for the first time.

Statistical Survey of Collisionless Dissipation in the Terrestrial Magnetosheath

Kinetic dissipation of turbulence is an important physical process occurring in collisionless plasmas. Using in‐situ data from the Magnetospheric Multiscale (MMS) Mission, we investigate the

We investigate properties of solar-wind-like plasma turbulence using direct numerical simulations. We analyze the transition from large, magnetohydrodynamic (MHD) scales to the ion characteristic

Kinetic simulations based on the Eulerian Hybrid Vlasov-Maxwell (HVM) formalism permit the examination of plasma turbulence with useful resolution of the proton velocity distribution function (VDF).



Cascade of kinetic energy in three-dimensional compressible turbulence.

The conservative cascade of kinetic energy is established using both Fourier analysis and a new exact physical-space flux relation in a simulated compressible turbulence, indicating a statistical self-similarity of kineticEnergy cascades.

Intermittent Dissipation and Heating in 3D Kinetic Plasma Turbulence.

High resolution, fully kinetic, three dimensional simulation of collisionless plasma turbulence shows the development of turbulence characterized by sheetlike current density structures spanning a range of scales, and presents evidence that these current sheet structures are sites for heating and dissipation, and that stronger currents signify higher dissipation rates.

It is proved that interscale transfer of kinetic energy in compressible turbulence is dominated by local interactions, and establishes the existence of an ensuing inertial range over which mean subgrid scale kinetic energy flux becomes constant, independent of scale.

Intermittent dissipation at kinetic scales in collisionless plasma turbulence.

High resolution kinetic simulations of collisionless plasma driven by shear show the development of turbulence characterized by dynamic coherent sheetlike current density structures spanning a range of scales down to electron scales, indicating that kinetic scale plasma, like magnetohydrodynamics, becomes intermittent due to current sheet formation.
