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 o…
A Deterministic Ionization Algorithm for the OSIRIS Particle-in-Cell Framework
Stephen DiIorio, Ricardo Fonseca, Frank Tsung +2
Ionization is critical in the formation and evolution of plasma dynamics; collisional ionization, in particular, is an often overlooked source of electrons when dealing with laser-…
Pair-loaded electron-only magnetic reconnection using laser-driven capacitor coils
Brandon K. Russell, Qian Qian, Rebecca Fitzgarrald +12
We propose and simulate a laboratory platform to study the effects of positrons in magnetic reconnection using laser-driven capacitor coils. Using particle-in-cell simulations, we…
A Fully Spin and Polarization Resolved Strong Field QED Algorithm for Particle-in-Cell Codes
Q. Qian, D. Seipt, M. Vranic +3
Modern ultra-intense laser facilities can generate electromagnetic fields strong enough to accelerate particles to near-light speeds over micron-scale distances and also approach t…
High brightness multi-MeV photon source driven by a petawatt-scale laser wakefield accelerator
E. Gerstmayr, B. Kettle, M. J. V. Streeter +16
We present an experimental demonstration of a bright multi-MeV gamma source driven by a petawatt laser. The source generates on average photons above 1 MeV…
Bright polarised x-ray flashes from dense plasmas
Q. Qian, C. P. Ridgers, S. V. Bulanov +5
Creating a plasma dominated by strong-field QED (SFQED) effects is a major goal of new multi-PW laser facilities. This is motivated by the fact that the fundamental dynamics of suc…
