Posted on June 5, 2013 by Physics Today · BBC: Electroencephalography (EEG) measures electrical activity on the scalp generated by the firing of neurons in the brain. Pilot's brain waves remotely control the flight of a model helicopter. As such, they have been studied as models for many important natural phenomena, such as deep water waves, ion-acoustic waves in plasmas, and propagation of laser pulses in optical fibers. Do such waves occur in plasmas, the most prevalent state of matter in the universe? The physics of Alfven waves book download. As they flow past each other, slight ripples can be quickly amplified into the giant waves loved by surfers. ABSTRACT: The work I will present focuses on a high power electromagnetic pulse in the electron plasma frequency range impinging on a fully magnetized plasma, at the Large Plasma Device (LAPD) at UCLA. In a plasma, atomic nuclei (ions) are separated from electrons, and immensely strong electric fields can build up between the oppositely charged particles when they are separated by the waves behind a powerful laser pulse. Confirmation that interacting magnetic plasma waves can generate “daughter” waves of a higher frequency supports the current picture of how turbulence leads to heat in astrophysical plasma. Waves in plasmas generated by a rotating magnetic field and implications to radiation belts. Like gases, they are made of particles bumping around in a shapeless glob. The concepts of plasma description by magnetohydrodynamics, kinetic theory, and particle simulation are stepwise introduced. 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. Collective processes are discussed in terms of plasma waves and instabilities. The study, based on data from ESA's Cluster mission, has mapped different types of electrostatic waves in this region.

A recently published article treating thermal waves in a magnetized plasma is explained for a non-technical audience as an example of current research in plasma physics.
