  • Les Houches school to be co-organized by EPP member Thomas G

    The next edition of the Les Houches plasma physics school will be co-organized by EPP researcher Thomas G and Mickael Grech (LULI, France) in May 2023. The school was planned to occur in 2021, but it was cancelled due to the COVID-19 pandemic.

    The Les Houches plasma physics school is typically organized every two years at Les Houches, in the beautiful Chamonix Valley in the french Alps, gathering a group of renowned lecturers in plasma physics. Space, astrophysical as well as laboratory plasmas will be considered with a special emphasis on the timely topic of plasmas under extreme conditions as found e.g. in the interior of planets, in the most violent astrophysical environments, or created using extreme-light lasers.

    EPP students and lecturers have participated in previous editions of this school in 2013, 2015, and 2019.

  • 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.

  • Work by Mario Galletti et al. featured on the cover of HPLSE

    The paper “Ultra-broadband near-IR NOPAs based on the nonlinear crystals BiBO and YCOB” by Mario Galletti et al. is featured on the cover of the latest issue of the journal High Power Laser Science and Engineering.

    In this work, the GoLP/IPFN researchers from Universidade de Lisboa, in collaboration with colleagues from the Central Laser Facility, STFC, United Kingdom, consider two alternative crystals for both low- and high-energy, few-cycle optical parametric chirped pulse amplification: bismuth borate (BiBO) and yttrium calcium oxyborate (YCOB).

    The experimental work was performed at IST Laboratory for Intense Lasers (L2I), where they developed a noncollinear optical parametric amplification (NOPA) setup seeded by a continuum pulse generated from a sapphire plate, operating in the near-infrared region, in order to test each crystal.

    For a 5 mm YCOB crystal, they obtained an amplified bandwidth of 200 nm and a gain of ~100, and for a 2.5 mm BiBO crystal they obtained an amplified bandwidth of 240 nm…
