Coherent axion electrodynamics in OSIRIS: a counter-propagating axion-photon parametric instability
Miles Radford, Pablo Bilbao, Thomas Grismayer +4
We present a coherent axion-electrodynamics extension of the OSIRIS particle-in-cell code and use it to identify and benchmark a parametric axion-photon instability supported by tw…
Two-Phase Structure of Synchrotron-Cooling-Unstable Relativistic Plasma
Agnieszka Wierzchucka, Pablo J. Bilbao, Robert J. Ewart +2
Using analytic theory, radiative particle-in-cell (PIC) simulations, and fluid simulations, we show that relativistic, synchrotron-cooling, collisionless, high- pair plasmas fil…
An axion framework for Particle-in-Cell codes with Monte-Carlo sampling: emission, absorption, and detailed balance in plasmas
Miles Radford, Ahmed Alsulami, Bertrand Martinez +5
We present an extension of the OSIRIS particle-in-cell (PIC) code that introduces an axion macroparticle species and three axion-production channels commonly used in thermal-plasma…
Double-Adiabatic Equations of State for Relativistic Plasmas
Agnieszka Wierzchucka, Pablo J. Bilbao, Alexander G. R. Thomas +2
The adiabatic equation of state describes the pressure evolution of highly collisional, isotropic plasmas in terms of their density, providing a possible closure of…
General-relativistic and non-ideal radiative cooling in neutron star magnetospheres
João Joaquim, Francisco Assunção, Pablo J. Bilbao +1
Radiation reaction cooling plays an important role in describing the extreme plasma conditions found in the magnetospheres of astrophysical compact objects. Strong electromagnetic…
Laboratory observation of collective beam-plasma instabilities in a relativistic pair jet
J W D Halliday, C D Arrowsmith, A M Goillot +37
We report on a measurement of collective behavior in a relativistic electron-positron pair plasma produced in the laboratory. Using the Fireball platform at CERN's HiRadMat facilit…
Learning collision operators from plasma phase space data using differentiable simulators
Diogo D. Carvalho, Pablo J. Bilbao, Warren B. Mori +2
We propose a methodology to infer collision operators from phase space data of plasma dynamics. Our approach combines a differentiable kinetic simulator, whose core component in th…
