Fluid descriptions of quantum plasmas

Transport in ITER-like plasmas in neoclassical, fluid and gyrokinetic descriptions

Abstract. Turbulent and neoclassical transport in a reference hybrid-mode ITER plasmas is studied using a hierarchy of modeling tools. Transport from ITG/TEM instability is studied with nonlinear gyrokinetic simulations and compared with results from quasilinear fluid and gyro-Landau fluid models. Simulations include full kinetic ion and electron dynamics, although a pure-D mixture is assumed f...

Hybrid Particle/Fluid Modeling of Plasmas

Particle in cell (PIC) methods enjoy great success in modeling devices that include moderately dense plasmas. However, as the plasma density becomes high in a large volume, the number of particles to track becomes computationally prohibitive. Reducing the number of particles by creating larger “macro particles” introduces significant numerical error. Alternatively, highdensity plasmas in large ...

Electromagnetic and Fluid Analysis of Collisional Plasmas

Kinetic theory for quantum plasmas

Quantum plasmas have been studied theoretically for more than four decades. Important early applications include the electron gas in metals and the electron-hole plasma in semiconductors and dimensionally reduced nanostructures. Experiments with lasers and ion beams are now making dense quantum plasmas of electrons and (classical) ions accessible in the laboratory giving rise to increased theor...

How to model quantum plasmas

Traditional plasma physics has mainly focused on regimes characterized by high temperatures and low densities, for which quantummechanical effects have virtually no impact. However, recent technological advances (particularly on miniaturized semiconductor devices and nanoscale objects) have made it possible to envisage practical applications of plasma physics where the quantum nature of the par...
