Trapping: The "Waterfall" of Vlasov-Poisson Dynamics and the Post-Transient Emergence of Drift-Independent Hole Structures in Collisionless Plasmas
Hans Schamel
A key aspect of structure formation in collisionless plasmas is particle trapping or, more precisely, the gap this process leaves in the theoretical description. While the dynamics…
On the linearity and stability of electrostatic structures based on the Schamel equation
Hans Schamel, Efim Pelinovsky, Marcelo V Flamarion
This paper contributes in the first part to the correct understanding of the linear limit in the Schamel equation (S-equation) from the perspective of structure formation in collis…
Pattern formation in Vlasov-Poisson plasmas beyond Landau caused by the continuous spectra of electron and ion hole equilibria
Hans Schamel
This review presents an upgraded wave theory adapted to the high fluctuation level of driven realistic i.e. non-idealized plasmas. Above all, this means giving up the well-known co…
Ultra slow electron holes in collisionless plasmas: stability at high ion temperature
D. Mandal, D. Sharma, H. Schamel
Numerical simulations recover ultra slow electron holes (EH) of electron-acoustic genre propagating stably well below the ion acoustic speed where the ion response disallows any kn…
Electron hole instability in linearly sub-critical plasmas
Debraj Mandal, Devendra Sharma, Hans Schamel
Electron holes (EH) are highly stable non-linear structures met omnipresently in driven collision-less hot plasmas. A mechanism destabilizing small perturbations into holes is esse…
The successive formation and disappearance of density structures in simple expanding systems
A. R. Karimov, H. Schamel
The Lagrangian fluid description is employed to solve the initial value problem for one-dimensional, compressible fluid flows represented by the Euler-Poisson system. Exact nonline…
