Large ensembles of charged particles (electrons and ions), aka plasmas, are ubiquitous in Nature. It is often claimed that 99% of matter in the Universe is in plasma state [1, 2]. By their very nature, a plasmas is a highly complex many-body system, whose dynamics in subject to a plethora of physical mechanisms, including long-range inter-particle interactions (“collisions”) and interactions with electric or/and magnetic fields, among others. The intricate interplay among these mechanisms allows for a rich dynamics that makes plasmas an excellent test-bed for nonlinear theories [3]. Among a wide variety of phenomena, collective excitations occur in a plasma: these are propagating vibrations (i.e. waves), characterized by the inherent dispersion and nonlinearity of the plasma medium, in addition to various other mechanisms (e.g. dissipation, forcing and “noise”, among others).
