In a recent Letter in Physical Review D, selected for the Physics newsmagazine of the American Physical Society and as Editor’s Suggestion, a team of researchers of GoLP (Nitin S, now at CINECA, Kevin S, now in Bochum U, and Luis OS), established a new strong bound on dark electromagnetism, the equivalent of electromagnetism to dark mattter. Dark matter and its properties are at the core of some of the most fundamental questions in physics and the present work shows that plasma physics inspired models and simulations can help constrain some of the properties of dark matter.
The simplest model for an electromagnetic-like interaction in the dark sector is equivalent to the electromagnetic interaction between opposite dark charge identical mass particles i.e. dark electromagnetism. Under this hypothesis, dark matter can behave like a cold collisionless plasma of self-interacting dark matter particles, and exhibit plasma-like instabilities with observational consequences.The…

In 2020, the Ministry of Science celebrates 25 years of the first Ministry of Science in Portugal. Our team will be present with the installation of Giannandrea I and Fabio C, Turbulence Voice of Space and GoLP VR Lab on April 17th 2020 in Teatro Thalia.

 

And now they come in three flavours! Following our tradition (see the “2014 Natas”, “2015 Natas”, “2016 Natas”, “2017 Natas”, “2018 Natas“), the prizes for the winners of the image, video, and VR of 2019, the “natas” of visualization, were awarded to Kevin Schoeffler (center), Nitin Shukla (right, in the slide, 2nd time winner), and Fabio Cruz (left, 4th time winner). The term “Nata” was coined by one of the previous winners Paulo Alves: “Nata” is a tasty Portuguese pastry that everybody likes. It’s as enjoyable as having our simulations running nicely on a big supercomputer. It can also mean being at the top, at a high level, important.” Nata is also a new open source visualisation framework recently launched by epp team members. Many congratulations to the 2019 winners! The images and videos have been posted on the team website here and will…

Luis OS will deliver a plenary talk at the 47th European Physical Society Conference on Plasma Physics (EPS2020) in Sitges near Barcelona, Spain, that will be held from June 22 to 26, 2020. The talk will address recent advances in the emerging field of extreme plasma physics.

On December 5 2019, Luis OS was elected corresponding member of the Academy of Sciences of Lisbon. Founded in 1779, the Academy of Sciences of Lisbon, comprises two classes (Sciences and Letters), each with seven sections, with up to 5 members and 10 corresponding members per class. Luis OS was elected in the section of Physics.

Happy holidays to all our researchers, professionals, families, alumni, and friends, and a Happy 2020 with lots of personal and professional successes and great science! (and don´t forget to check the GoLP VR Lab with your new Oculus!)

In the most recent PRACE call for supercomputing time, Luis Silva and Jorge Vieira, GoLP/IPFN researchers and professors in the physics department, have received 36 million cpu-core hours for MareNostrum in Spain and 60 million cpu-core hours for Piz Daint in Switzerland, respectively. The award for Luis Silva is the second year renewal of the project PULSAR, aimed at understanding, from first principles, the magnetosphere of compact objects such as pulsars and black holes, and the award for Jorge Vieira is for the one year project OptiMom, with the goal of investigating how intense laser beams with exotic properties could enhance compact plasma accelerators and light sources. The estimated combined value of these awards exceeds 2 Million euros, and corresponds to the computing power of 11000 cores running continuously for one year.

Our team member Nitin S has successfully defended his PhD thesis on June 19, 2019. Many congratulations to Nitin (center) and all the best for his future life & sci endeavors In the picture, Nitin rejoices with his thesis committee (from left to right: Ricardo F, Jorge V, Nitin S, Bob Bingham and Tito Mendonça).

GoLP organised and hosted the visit of Gérard Mourou to Portugal that included talks at Pavilhão do Conhecimento, at IST, and at U.Porto, with dinner with GoLP PIs, the president of IPFN, and the president of DF, and the visit to one of the CPA labs of GoLP.

Luis OS, Ricardo F, Thomas G, and Marija V attended SPIE 2019 in Prague, from April 1st to April 3rd to deliver invited talks on extreme plasma physics, exascale computing, beam-beam physics and probing strong-field QED, and positron and gamma ray sources from intense laser-matter interactions.This was also an opportunity to strengthen our ongoing collaborations and discuss joint projects with several of the attendees.
