Probe theories are only applicable in the regime where the probe’s perturbation of the plasma can be neglected. However, it is not always possible to know, a priori, that a particular probe theory can be successfully applied, especially in low density plasmas. is is especially difficult in the case of transient, low density plasmas. Here, we applied probe diagnostics in combination with a 2D p...

Abstract. We calculate the wake induced in a hot QCD plasma by a fast parton in the framework of linear response theory. We discuss two scenarios: (i) a weakly coupled quark-gluon plasma described by hard-thermal loop perturbation theory and (ii) a strongly coupled quark-gluon plasma which resembles a quantum liquid. We show that a Mach cone can appear in the second scenario, but not in the fir...

Using techniques of effective field theory, we consider the thermodynamical properties of a dilute two-dimensional plasma interacting via a 1/r potential. The first one-loop correction to the partition function is already logarithmically divergent in the effective theory. The finite part of the one-loop induced couplings is then explicitly evaluated by matching the density-density correlator in...

By orbit-limited motion (OLM) theory and the kinetic model, currents carried by electronsand ions on the dust grain are obtained and the effects of temperature and drift velocity of ions on thedust grain electrical potential are considered. The calculations were performed for finding the role of densities of dust grains and ions on the dust grain electrical potential which is the ma...

A microscopic eikonal theory based on photon wave mechanics is established. The diamagnetic (solid state) eld-plasma interaction is shown to play a central role in the theory, and this interaction enables one to introduce a massive transverse photon concept. This quasi-particle enters the eikonal theory in manner similar to the one in which the classical point particle enters Newtonian Mechanic...

on the source of plasma density and electric field perturbations in pmse and pmwe regionspolar mesospheric summer/winter echoes (pmse/pmwe) are very strong radar echoes produced by ionospheric electron density fluctuations at half the radar wavelength. the main focus of this paper is the altitude range 80 to 90 km in summer and altitude range 65-86 km in winter in the polar mesosphere . this pa...

The current theory is closely examined, and found to have inconsistencies. A new theory is developed with new results for both the energy and magnetic moment of a charged particle. The new theory predicts particle behaviour which is opposite to convention: for example, that a plasma will decelerate as it moves through a decreasing magnetic field. Conversely it will accelerate into an increasing...

Abstract Interactions between plasma particles and electromagnetic waves play a crucial role in the dynamics regulation of state space environments. From physics theory, characteristics their interactions with strongly depend on composition plasma, among other factors. In case Earth’s magnetosphere, is usually composed electrons, protons, O+ ions, He+ all particular properties characteristics. ...
