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…
Radiation reaction cooling as a source of anisotropic momentum distributions with inverted populations
Pablo J. Bilbao, Luis O. Silva
Under the presence of strong electromagnetic fields and radiation reaction, plasmas develop anisotropic momentum distributions, characterized by a population inversion. This is a g…
Kinetic theory of particle-in-cell simulation plasma and the ensemble averaging technique
Michael Touati, Romain Codur, Frank Tsung +3
We derive the kinetic theory of fluctuations in physically and numerically stable particle-in-cell (PIC) simulations of electrostatic plasmas. The starting point is the single-time…
Machine Learning-based models in particle-in-cell codes for advanced physics extensions
Chiara Badiali, Pablo J. Bilbao, Fábio Cruz +1
In this paper we propose a methodology for the efficient implementation of Machine Learning (ML)-based methods in particle-in-cell (PIC) codes, with a focus on Monte-Carlo or stati…
Coherent emission from QED cascades in pulsar polar caps
Fábio Cruz, Thomas Grismayer, Alexander Y. Chen +2
Pulsar magnetospheres are thought to be filled with electron-positron plasma generated in pair cascades. The driving mechanism of these cascades is the emission of gamma-ray photon…
The impact of kinetic effects on the properties of relativistic electron-positron shocks
A. Stockem, F. Fiuza, R. A. Fonseca +1
We assess the impact of non-thermally shock-accelerated particles on the magnetohydrodynamic (MHD) jump conditions of relativistic shocks. The adiabatic constant is calculated dire…
