“…Different techniques are needed to model the plasma sources, the chemical and surface interactions, and the microscopic processes in the etching of patterns. The plasma is usually modelled with hybrid codes which treat them as a fluid except where particle kinetics is necessary, such as in reactive collisions 32,33 . In this direction, several models have been proposed.…”

The phenomenon of vibrational resonance (VR) is examined and analyzed in a bi-harmonically driven two-fluid plasma model with nonlinear dissipation. An equation for the slow oscillations of the system is analytically derived in terms of the parameters of the fast signal using the method of direct separation of motion. The presence of a high frequency externally applied electric field is found to significantly modify the system's dynamics, and consequently, induce VR. The origin of the VR in the plasma model has been identified, not only from the effective plasma potential but also from the contributions of the effective nonlinear dissipation. Beside several dynamical changes, including multiple symmetry-breaking bifurcations, attractor escapes, and reversed period-doubling bifurcations, numerical simulations also revealed the occurrence of single and double resonances induced by symmetry breaking bifurcations.

“…In this regard, numerical simulations play an important role complementing the analytical theories. Over the past decades, many numerical studies have been performed to reveal various nonlinear phenomena in the Buneman instability [18][19][20][21][22][23] . Despite these efforts, however, theoretical explanations for a variety of the observed nonlinear phenomena remain elusive.…”

Backward waves in the nonlinear regime of the Buneman instability

et al. 2021

Observation of low-and high-frequency backward waves in the nonlinear regime of the Buneman instability is reported. Intense low-frequency backward waves propagating in the direction opposite to the electron drift (with respect to the ion population) of ions and electrons are found. The excitation of these waves is explained based on the linear theory for the stability of the electron velocity distribution function that is modified by nonlinear effects. In the nonlinear regime, the electron distribution exhibits a wide plateau formed by electron hole trapping and extends into the negative velocity region. It is shown that within the linear approach, the backward waves correspond to the weakly unstable or marginally stable modes generated by the large population of particles with negative velocities.

“…Since the pioneer work of Oscar Buneman 11,12 ; a lot of work has been done to understand linear and nonlinear evolution of Buneman instability in the non-relativistic 13,[23][24][25][26][27][28][29][30][31][32][33][34][35][36] and relativistic 18,19,[37][38][39] regime. Various approaches are attempted by several authors [23][24][25] to estimate the saturation value of the Buneman instability; among them Hirose's 25 model successfully predicted that at the quasilinear saturation (or first saturation) the ratio of electrostatic energy density ( k |E k | 2 /8π) to initial kinetic energy density (W 0 = (1/2)n 0 mv 2 0 ) varies with electron to ion mass ratio as ∼ (m/M ) 1/3 .…”

Spatio-temporal evolution of Buneman instability has been followed numerically till its quasilinear quenching and beyond, using an in-house developed electrostatic 1Dand for a wide range of electron to ion mass ratios (m/M), growth rate obtained from simulation agrees well with the numerical solution of the fourth order dispersion relation. Quasi-linear saturation of Buneman instability occurs when ratio of electrostatic field energy density () reaches up to a constant value, which as predicted by Hirose [Plasma Physics 20, 481(1978)], is independent of initial electron drift velocity but depends on electron to ion mass ratio m/M as. This result stands verified in our simulations. Growth of the instability beyond the first saturation (quasilinear saturation ) till its final saturation [Ishihara et. al., PRL 44, 1404(1980] follows an algebraic scaling with time. In contrast to the quasilinear saturation, the ratio of final saturated electrostatic field energy density to initial kinetic energy density, is relatively independent of electron to ion mass ratio and is found to depend only on the initial drift velocity. Beyond the final saturation, electron phase space holes coupled to large amplitude ion solitary waves, a state known as coupled hole-soliton , are seen in our simulations. The propagation characteristics ( amplitude -speed relation ) of these coherent modes is found to be consistent with
