Ion acceleration and coherent structures generated by lower hybrid shear-driven instabilities

Journal Article Romero, H ; Ganguli, G ; Lee, Y C - Physical Review Letters; (United States)

It is shown that if [kappa]=[omega][sub [ital S]]/[omega][sub LH][gt]1 ([omega][sub [ital S]] and [omega][sub LH] are the shear and lower hybrid frequencies), a sheared electron cross-field flow excites the electron-ion-hybrid mode, causing significant perpendicular ion acceleration. The electric potential develops coherent structures (vortexlike) longer than the electron Larmor radius, [rho][sub [ital e]]. For [kappa][lt]1, a smooth transition occurs where the wavelength becomes of the order of [rho][sub [ital e]], the lower hybid drift instability dominates, and the formation of vortexlike structures is no longer observed. The results are relevant to laboratory, laser-produced, and space plasmas.

Phase space coherent structure of charged particles system

Journal Article Lin, H ; Shen, B F ; Xu, Z Z - Physics of Plasmas

A class of 3-D numerical solutions of Vlasov-Maxwell equation set is obtained from standard power series solution. Such a class of 3-D numerical solutions corresponds to some phase space coherent structures in electron distribution function, which are more complicated than the well-known hole structure. Based on these solutions, various profiles of related physical quantities are also calculated.

Transverse instability and magnetic structures associated with electron phase space holes

Journal Article Aimin, Du ; Mingyu, Wu ; Quanming, Lu ; ... - Physics of Plasmas

Electron phase space holes (electron holes) are found to be unstable to the transverse instability. Two-dimensional (2D) electromagnetic particle-in-cell simulations are performed to investigate the structures of the fluctuating magnetic field associated with electron holes. The combined actions between the transverse instability and the stabilization by the background magnetic field (B{sub 0}=B{sub 0}e-vector{sub x}) lead a one-dimensional electron hole into several 2D electron holes which are isolated in both the x and y directions. The electrons trapped in these 2D electron holes suffer the electric field drift v{sub E}=ExB{sub 0}/B{sub 0}{sup 2} due to the existence of the perpendicular electricmore »« less

Multistability and phase-space structure of dissipative nonlinear parametric four-wave interactions

Journal Article Coninck, J C.P. ; Lopes, S R ; Viana, R L - Physical Review. E, Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics

We investigate the phase-space structure displayed by a system of four waves interacting by means of nonlinear coupling between two wave triplets, which results in a dissipative high-dimensional vector field presenting an invariant manifold, wherein the dynamics is essentially conservative. The focus is on the coexistence of a large number of periodic attractors in the phase space, with an interwoven structure of the basins of attraction, where low-period attractors have predominance. The time behavior of nearly conserved quantities and the properties of the Lyapunov spectra are used to imply the existence of a lower-dimensional invariant manifold where the dynamics ismore »« less

Anomalous resistivity of current-driven isothermal plasmas due to phase space structuring

Journal Article Buechner, Joerg ; Elkina, Nina - Physics of Plasmas

The anomalous electric resistivity of collisionless plasmas is an important issue in the physics of hot plasmas, e.g., in the context of auroral particle acceleration and of reconnection in the solar corona. The linear stability theory of isothermal current driven space plasmas predicts an ion-acoustic instability if the relative drift velocity of the current carrying particles exceeds a certain threshold, which, generally, depends on the plasma parameters. The spectrum of waves, excited by a marginal instability, is very narrow. Hence, the wave power at saturation and the corresponding electric resistivity due to wave-particle interaction cannot be obtained by means ofmore »« less
