plasma oscillation

Field worked on plasma oscillations and later became interested in cosmology.

In physics, a plasmon is a quantum of plasma oscillation.

They are also inherently unstable, prone to phenomena such as plasma oscillation and thermal runaway.

This is a plasma oscillation resonance or plasmon.

In the moving frame of the electron beam, the velocity modulation is equivalent to a plasma oscillation.

Alfvén waves (low frequency hydromagnetic plasma oscillations) are named in his honor.

Its name is an abbreviation of the term transmission line shunted plasma oscillation qubit.

To visualize a plasma oscillation, imagine a cube of metal placed in an external electric field pointing to the right.

They are similar in geometry to plasma oscillations in that they have to be transversal.

Plasma oscillations are rapid oscillations of the electron density in conducting media such as plasmas or metals.

Since plasmons are the quantization of classical plasma oscillations, most of their properties can be derived directly from Maxwell's equations.

In a bounded plasma, fringing electric fields can result in propagation of plasma oscillations, even when the electrons are cold.

The idea is that a laser which delivers a large amount of power in a very short pulse can cause ionization in a gas followed by plasma oscillation.

It is possible to imagine Plasma oscillation as waves in the sea, and the particles as surfers trying to catch the wave, all moving in the same direction.

If the plasma frequency is higher than the cyclotron frequency, then the upper hybrid oscillation transforms continuously into the plasma oscillation.

A plasmon is a collective excitation, which is the quantum of plasma oscillations (wherein all the electrons simultaneously oscillate with respect to all the ions).

Plasma oscillations caused energy to flood out of the core, in neutrino-antineutrino pairs, and the birds swooped around the core, drinking in this glow of new radiance.

Other quasiparticles or collective excitations include phonons (particles derived from the vibrations of atoms in a solid), plasmons (particles derived from plasma oscillations), and many others.

Electron gas can undergo plasma oscillation, which is waves caused by synchronized variations in electron density, and these produce energy emissions that can be detected by using radio telescopes.

Otherwise, the frequency of the mode related to the upper hybrid oscillation remains above the cyclotron frequency, and the mode related to the plasma oscillation remains below the plasma frequency.

Plasma frequency: The electron plasma frequency (measuring plasma oscillations of the electrons) is large compared to the electron-neutral collision frequency (measuring frequency of collisions between electrons and neutral particles).

The plasmon is a quasiparticle resulting from the quantization of plasma oscillations just as photons and phonons are quantizations of electromagnetic and mechanical vibrations, respectively (although the photon is an elementary particle, not a quasiparticle).

This oscillation is closely related to the plasma oscillation found in unmagnetized plasmas or parallel to the magnetic field, where the ω term arises from the electrostatic restoring force and the 3k2v2 term arises from the restoring force of electron pressure.

Discrepancies with the Boltzmann relation can occur, for example, when oscillations occur so fast that the electrons cannot find a new equilibrium (see e.g. plasma oscillations) or when the electrons are prevented from moving by a magnetic field (see e.g. lower hybrid oscillations).
