We report on a single-state measurement of electrical conductivity of warm dense gold in the solid to plasma transition regime. This is achieved using the idealized slab plasma approach of isochoric heating of ultrathin samples by a femtosecond laser, coupled with femtosecond probe measurements of reflectivity and transmission. The experiment also reveals the time scale associated with the disa...

Using particle-in-cell (PIC) simulations, we study the evolution of a strongly magnetized plasma slab propagating into a finite density ambient medium. Like previous work, we find that the slab breaks into discrete magnetic pulses. The subsequent evolution is consistent with diamagnetic relativistic pulse acceleration of [10]. Unlike previous work, we use the actual electron to proton mass rati...

ABSTRACT The modulation of the intensity microwave emission from a plasma slab caused by standing linear kink fast magnetoacoustic wave is considered. stretched along straight magnetic field, and can represent, for example, current sheet in flaring active region corona Sun, or streamer pseudostreamer stalk. density non-uniform perpendicular direction described symmetric Epstein profile. paramet...

The quasilinear scattering mean free path of solar flare electrons and nucleons is calculated for interplanetary plasma wave turbulence consisting of a mixture of slab shear Alfvén waves and isotropic fast magnetosonic waves. It is shown that for well-sampled electron and nucleon mean free paths over a wide and overlapping energy range the underlying frequency power spectra of left-handed and r...

The generation of shear flow by drift waves is an important area of investigation. In a recent paper @Chen et al., Phys. Plasmas 7, 3129 ~2000!# an elegant formalism was developed for the generation of shear/zonal flows by drift waves in a toroidal plasma. The study of shear flow generation in fluids and plasmas is put into perspective. In this paper it is shown how a simple slab geometry analy...
