Characteristics of monotonic sheaths near a wall with grazing magnetic incidence
Alessandro Geraldini, Robert J. Ewart, Stephan Brunner +1
We consider a magnetised plasma in contact with an absorbing planar wall, where the angle between the magnetic field and the wall is small, (in radians) and the system…
Universal fluctuation spectrum of Vlasov-Poisson turbulence
Michael L. Nastac, Robert J. Ewart, James Juno +2
The thermal fluctuation spectrum of the electric field arising due to particle noise in a quiescent Vlasov-Poisson plasma was derived in the 1960s. Here, we derive the universal fl…
Relaxation to universal non-Maxwellian equilibria in a collisionless plasma
Robert J. Ewart, Michael L. Nastac, Pablo J. Bilbao +3
Generic equilibria are derived for turbulent relaxing plasmas via an entropy-maximization procedure that accounts for the short-time conservation of certain collisionless invariant…
Ring momentum distributions as a general feature of Vlasov dynamics in the synchrotron dominated regime
Pablo. J. Bilbao, Robert J. Ewart, Francisco Assunçao +2
We study how radiation reaction leads plasmas initially in kinetic equilibrium to develop features in momentum space, such as anisotropies and population inversion, resulting in a…
Phase-space entropy cascade and irreversibility of stochastic heating in nearly collisionless plasma turbulence
Michael L. Nastac, Robert J. Ewart, Wrick Sengupta +3
We consider a nearly collisionless plasma consisting of a species of `test particles' in 1D-1V, stirred by an externally imposed stochastic electric field. The mean effect on the p…
