Cosmological Vlasov–Poisson equations for dark matter: recent developments and connections to selected plasma problems

C Rampf - Reviews of Modern Plasma Physics, 2021 - Springer
The cosmic large-scale structures of the Universe are mainly the result of the gravitational
instability of initially small-density fluctuations in the dark-matter distribution. Dark matter …

A simple, heuristic derivation of the Balescu–Lenard kinetic equation for stellar systems

C Hamilton - Monthly Notices of the Royal Astronomical Society, 2021 - academic.oup.com
The unshielded nature of gravity means that stellar systems are inherently inhomogeneous.
As a result, stars do not move in straight lines. This obvious fact severely complicates the …

Collisional simulations of the modulator section in coherent electron cooling

A Al Marzouk, B Erdélyi - Physical Review Accelerators and Beams, 2024 - APS
The first section of any coherent electron cooling (CeC) system is the modulator, where the
density of the electron beam is modulated by the copropagating ion beam. This density …

Unveiling the singular dynamics in the cosmic large-scale structure

C Rampf, U Frisch, O Hahn - Monthly Notices of the Royal …, 2021 - academic.oup.com
It is known that the gravitational collapse of cold dark matter leads to infinite-density caustics
that seed the primordial dark-matter haloes in the large-scale structure. The development of …

Nonlinear dynamics of nonadiabatic chirping-frequency Alfvén modes in tokamak plasmas

X Wang, S Briguglio, A Bottino, M Falessi… - Plasma Physics and …, 2023 - iopscience.iop.org
Frequency chirping of Alfvén modes, a phenomenon observed in tokamak fusion plasmas
driven by energetic particles (EPs), can result in significant losses of EPs. In this study, we …

Collision rates estimated from exact N-body simulations of a one-dimensional plasma

E Gravier, T Drouot, M Lesur, A Guillevic… - Physics of …, 2023 - pubs.aip.org
In a plasma, the charged particles interact via long-range forces, and this interaction causes
the plasma to exhibit collective effects. If the graininess or coupling parameter g goes to zero …
