• Magnetogenesis explored in simulations published in Physical Review Letters

    The universe is filled with magnetic fields. However, it is widely accepted that in the early universe they did not exist. An important scientific question is how these magnetic fields could have grown from nothing to the level we find them today. epp team members, Ricardo Fonseca and Luís O. Silva, collaborated with  Kevin Schoeffler, and Nuno Loureiro on a paper published in Physical Review Letters addressing this issue. They demonstrate using first principle simulations how magnetic fields are formed by only gradients in the pressure and density. This generation of magnetic fields also plays an important role in many high power laser experiments, which generate magnetic fields on the order of megagauss. These fields form via both the previously predicted Biermann battery mechanism as well as a kinetic plasma instability known as the Weibel instability, depending on the system parameters. These results should have an important impact on both the…

  • EPP team alumnus wins prestigious prize

    The IUPAP General Relativity and Gravitation Young Scientist Prize 2014 was awarded to Jorge Santos, epp team alumni (2002-2005). This is one of the most prestigious prizes for young scientists working in General Relativity. Jorge concluded his MSc at IST in 2005 on parametric instabilities driven by white light, from which resulted two papers (Physical Review Letters and Journal of Mathematical Physics). Jorge is now a Lecturer in Cambridge University, on leave at Stanford University.

  • Paper published in Phys. Rev. Lett. demonstrates the seeding of the self-modulation instability

     
    Paper ’Seeding of Self-Modulation Instability of a Long Electron Bunch in a Plasma’ by Y. Fang et al was published in Physical Review Letters. It describes a series of experiments performed in the Accelerator Test Facility (ATF) at Brookhaven National Laboratory demonstrating the seeding of the self-modulation instability by long bunches with sharp rise density profiles. This work supports the concept of similar experiments in the future, e.g. Self-Modulation Instability (SMI) experiments using long bunches of relativistic protons. More information can be read here.

  • Thomas Grismayer obtains a Starting Grant from FCT

    Thomas Grismayer has been awarded a prestigious FCT Investigator contract in this year’s extremely competitive contest for these new positions.
    Thomas obtained a Starting Grant for his proposal title “Pair dominated plasmas in ultra intense fields: from the laboratory to astrophysics.” The central scientific questions and the research focus of this project will be to determine the conditions for the creation of pair plasmas in the laboratory under the action of ultra intense fields (magnetic field and/or laser pulses) and to investigate the self-consistent collective dynamics of such plasmas with their radiation, both in laboratory and astrophysical conditions such as pulsars and magnetars.
