The plasmon can be considered a quasi particle since it arises from the quantization of plasma oscillations, just like phonons are quantization of mechanical vibrations.
Also, the Van der Pol Equation for Nonlinear Plasma Oscillations has been studied by Hafeez and Chifu in 2014 [12]; they showed that the Van der pol equation depends on the damping co-efficient [mu] which has varying behaviour.

However, in contrast to the oscillations at the frequencies within the electron cyclotron resonance range [13], the plasma oscillations of a certain ion kind can be excited by an ion beam consisted of another ion kind.
D], the plasma acts as a continuous medium in which the charged particles participate in collective behavior such as plasma oscillations.
Preliminary experiments from three countries indicate that when ultrashort light pulses (less than 40 quadrillionths of a second) are used, electrons might be accelerated by a novel mechanism in which laser light directly accelerates the electrons rather than indirectly through plasma oscillations.
