Since its public release in 2015, the [EPOCH][1] particle-in-cell community code has accumulated a large base of over 1100 registered users, becoming an indispensable workhorse tool for many groups worldwide whose research specialisation ranges from high-power laser-plasma interactions and QED-plasmas, to kinetic instabilities in tokamaks, space physics and particle accelerator design. EPOCH...

we consider a few options to access the ultimate QED limit of matter in the strong electro-magnetic field, when \xi \alpha^2/3 > 1, where \alpha=1/137 is the fine-structure constant and \xi is the nonlinear quantum parameter.
This regime of fully non-perturbative QED has long been assumed to be not accessible experimentally. Yet, the progress in laser technology and particle accelerators may...

Started in 2013, the electromagnetic PIC code SMILEI has achieved significant progress, both on the physics and performance aspects. To match its open-source and community-driven approach, it is now well documented and has a user-friendly design. New physics modules include collisions, ionization, radiation reaction, multiphoton Breit-Wheeler pair creation, an envelope model for laser-plasma...

Computing radiated fields from particle-in-cell (PIC) simulations are limited by the grid resolution. In PIC codes, the spatial scales are either the plasma skin-depth or the laser wavelength. Hence, resolving the radiated fields on the PIC grid requires extremely large computational resources. As the PIC codes can compute the particle trajectories for the entire simulation duration, a...
