WebThe vibrations of the electronic plasma are considered, which arise as a result of an arbitrary initial non-equilibrium distribution in it. It is shown that the vibrations of the field in plasma are always damped, and the dependence of the frequency and of the damping decrement on the wave vector is determined for small and for large values of the latter. WebIn physics, a plasmon is a quantum of plasma oscillation.Just as light (an optical oscillation) consists of photons, the plasma oscillation consists of plasmons.The plasmon can be considered as a quasiparticle since it arises from the quantization of plasma oscillations, just like phonons are quantizations of mechanical vibrations.
