Macroparticles with different weights relax to different temperatures in Particle-In-Cell simulations
Remi Lehe, Arianna Formenti, Justin R. Angus +1
A distinctive feature of Particle-In-Cell (PIC) simulations is the use of macroparticles, each representing many physical particles. The associated macroparticle weight can vary fr…
HiPACE++: a portable, 3D quasi-static Particle-in-Cell code
Severin Diederichs, Carlo Benedetti, Axel Huebl +6
Modeling plasma accelerators is a computationally challenging task and the quasi-static particle-in-cell algorithm is a method of choice in a wide range of situations. In this work…
A Hybrid Nodal-Staggered Pseudo-Spectral Electromagnetic Particle-In-Cell Method with Finite-Order Centering
Edoardo Zoni, Remi Lehe, Olga Shapoval +5
Electromagnetic particle-in-cell (PIC) codes are widely used to perform computer simulations of a variety of physical systems, including fusion plasmas, astrophysical plasmas, plas…
Porting WarpX to GPU-accelerated platforms
A. Myers, A. Almgren, L. D. Amorim +20
WarpX is a general purpose electromagnetic particle-in-cell code that was originally designed to run on many-core CPU architectures. We describe the strategy followed to allow Warp…
Pseudo-spectral Maxwell solvers for an accurate modeling of Doppler harmonic generation on plasma mirrors with Particle-In-Cell codes
G. Blaclard, H. Vincenti, R. Lehe +1
With the advent of PW class lasers, the very large laser intensities attainable on-target should enable the production of intense high order Doppler harmonics from relativistic las…
An efficient and portable SIMD algorithm for charge/current deposition in Particle-In-Cell codes
H. Vincenti, R. Lehe, R. Sasanka +1
In current computer architectures, data movement (from die to network) is by far the most energy consuming part of an algorithm (10pJ/word on-die to 10,000pJ/word on the network).…
A spectral unaveraged algorithm for free electron laser simulations
Igor A. Andriyash, Remi Lehe, Victor Malka
We propose and discuss a numerical method to model electromagnetic emission from the oscillating relativistic charged particles and its coherent amplification. The developed techni…
