Finding closure: approximating Vlasov-Poisson using finitely generated cumulants

C Uhlemann - Journal of Cosmology and Astroparticle Physics, 2018 - iopscience.iop.org
Since dark matter almost exclusively interacts gravitationally, the phase-space dynamics is
described by the Vlasov-Poisson equation. A key characteristic is its infinite cumulant …

Investigating the use of field solvers for simulating classical systems

A Eberhardt, A Banerjee, M Kopp, T Abel - Physical Review D, 2020 - APS
We explore the use of field solvers as approximations of classical Vlasov-Poisson systems.
This correspondence is investigated in both electrostatic and gravitational contexts. We …

Localized instabilities of the Wigner equation as a model for the emergence of Rogue Waves
