• 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.

  • Fundação Calouste Gulbenkian awards scholarship to Óscar A

    Óscar Amaro was awarded a scholarship “Novos Talentos em Tecnologias Quânticas” by Fundação Calouste Gulbenkian. In the next 10 months, Óscar will work on a research project that aims to apply quantum algorithms to a plasma physics problem, under supervision of Marija Vranic. This program has an objective to stimulate young scholars to study Quantum Technologies, thereby stimulating the development of national competences in this field.

  • “Turbulence | Voice of Space” featured in ERC social media

    Our scientific communication project “Turbulence | Voice of Space” was recently featured in European Research Council (ERC) social media. In a video created in the context of the ERC Public Engagement with Research Award announcement, Luis OS explains how creating virtual reality (VR) environments from real simulation data helped us engage experts and the general public with our research on extreme plasma astrophysics. Learn more about our VR Lab and check our demos here.

  • EPP researchers and IPFN collaborators propose new regime for superradiant emission in Nature Physics paper

    In a paper published today, September 14, in the journal Nature Physics, Extreme Plasma Physics (EPP) team members Jorge V., Miguel P. and Ricardo F. along with the founder of GoLP, Tito M., report a generalised superradiance mechanism, which uses transversely modulated – instead of longitudinally modulated – charged particle beams. Superradiant emission is desirable because it leads to the brightest x-ray beams, being at the core of free electron lasers. It has been long thought that the existence of many particles per radiated wavelength is a key requirement for superradiance. Fulfilling this requirement is a challenge, but according to the work published today, superradiance can occur even for bunches that are arbitrarily diluted, as long as they are suitably modulated in a transverse direction. This work thus breaks a long standing tenet at the core of today’s most advanced light sources. Generalised superradiance may…

  • Fabrizio del G is awarded PhD in Physics

    EPP team member Fabrizio del G has successfully defended his PhD thesis on September 8, 2020. Due to the current pandemic situation, Fabrizio’s defence was held remotely. His thesis committee was composed by Mattias Marklund (University of Gothenburg), Dmitri Uzdensky (University of Colorado Boulder), Jorge Vieira (IST) and Thomas Grismayer (IST), and was presided by Luis Lemos Alves (IST). Many congratulations to Fabrizio and the best wishes for his future life and career.
