We present experiments and theoretical studies on the propagation of Josephson fluxons and electromagnetic waves in parallel arrays of Josephson junctions in the limit of small discreteness. Illustration of this article EU-funded researchers in the UK and US have helped to solve the mystery of why the Sun's atmosphere is so much hotter than its surface. Work was on the boundaries of plasmas and ion rarefaction waves—most of the work was experimental using a Langmuir probe in the basement lab in Oxford's Engineering Science building. Weak shocks, i.e., those of small amplitude, can be well described within the hydrodynamic approximation. Shock waves are supersonic disturbances propagating in a fluid and giving rise to dissipation and drag. The ensuing plasma wave, measuring millions of degrees in temperature, lasted for. Analogously, just as buoyancy effects guide water waves, plasma oscillations are related to waves in the electron component of the plasma called Langmuir waves. The result: the magnetic fields fluctuate depending on their position in the plasma, however, regardless of time - unlike, for example, electromagnetic waves such as light waves, which fluctuate over time. Only compressive structures (density/potential hill) are found to exist that evolve due to the propagation of two types of waves, namely fast wave and slow wave. Two MIT scientists have shown that radio waves can be used to corral super hot plasmas in fusion reactors, a big break in turning fusion into reality. This Friday, a solar eruption of spectacular proportions took place. Physicists have succeeded in the first real-time observation of laser produced electron plasma waves and electron bunches accelerated by them. The theory of damping and nonlinear frequency shifts from particles resonant with ion-acoustic waves (IAWs) is presented for multi-ion species plasma and compared to driven wave Vlasov simulations. "At the heart of the theory is a pair of old, dense stars called white dwarfs, orbiting each other so closely that their gravitational forces create violent tidal waves of plasma that break near the surfaces of the stars. Due to their special properties, dust acoustic waves can propagate inside these plasmas like sound waves in air, and can be studied with the naked eye or with standard video cameras.
