• ZPIC featured in European project for optimization of HPC applications

    The joint European project Effort toward a Highly Productive Programming Environment for Heterogeneous Exascale Computing (EPEEC) has conducted a test on the effective advantages of task-based parallel programming models using ZPIC as a reference High-Performance Computing (HPC) application for kinetic plasma simulations. The results from this test show a path for alternative high-efficiency parallelization of the PIC algorithm that can be straightforwardly applied in many novel architectures, including FPGA and GPGPU based accelerators.
    Different task-based implementations of ZPIC have been developed based on the OmpSs-2 programming model and their performance was tested on two classical test plasma physics problems: laser wakefield acceleration and the Weibel instability. Some of the implementations demonstrated near-perfect scaling for 48 cores despite unbalanced conditions, an impressive result accomplished while retaining the code simplicity of task-based programming. More details of this study can be found here.
    EPEEC’s main goal is to…

  • News for International day of Women in Science

    GoLP is celebrating the international day of Women in Science by launching a Women in Physics group led by Camilla Willim, Marija Vranic, Mariana Moreira and Chiara Badiali. The primary goal of this group is forming and strengthening connections between PhD students at IST across different physics disciplines. Other initiatives will include outreach, coaching and connection with role-model female scientists through formal and informal events. This group’s activities will complement the efforts of Gender Balance @ Técnico, that has been active for the past few years.

  • Article by EPP researchers in PRE Spotlight

    The article “Seeded QED cascades in counter-propagating laser pulses” published in Physical Review E in 2017 by Thomas G, Marija V, Joana M, Ricardo F and Luis OS has been selected for a Physical Review E (PRE) Spotlight on Laser-created Pair Plasmas. Each PRE Spotlight represents a small selection of articles, dealing with the same research area. The article provides an exhaustive study about the growth rates of QED cascades in counter-propagating lasers. In addition to the new analytical work developed by the authors, all recent existing theoretical models for the growth rate from other authors are shown and compared to first-principles QED-PIC simulations. A discussion about the cascade’s threshold is included, based on the analytical and numerical results. The paper is available here.

  • Recent paper in PoP selected as an Editor’s Pick

    A recent paper in Physics of Plasmas by EPP members Bernardo M and Jorge V and collaborators at Rochester University, USA, entitled “Laser-plasma acceleration beyond wave breaking” has been selected by the editors of Physics of Plasmas as a featured article. This paper discusses how superluminal plasma wakefields prevent wave-breaking of strongly nonlinear plasma waves in the blowout regime and thus self-injection of electrons into the plasma wake. This leads to enhanced and cleaner accelerating fields. Our finding could be an important step to further reduce the size and improve the quality of future plasma based accelerators.
