Sergio Xavier, who obtained his Ph.D. from U. Federal do Pará, Brazil, under the supervision of Prof. L. Crispino in August 2024, received a best poster award in the XLII Brazilian National Meeting on the Physics of Particles and Fields. The poster was on work in collaboration with our group.
Three Gr@v members appear in the 2024 updated science-wide author databases of standardized citation indicators, commonly known as the Stanford University ranking of top 2% scientists in the world. The top 100 scientists in Portugal, from the same raking, features one CIDMA and Gr@v researcher.
Group get together to cellebrate Prof. Darío Nuñez, from UNAM, Mexico City, one year visit (Oct 2023 - Sep 2024). Many thanks Darío for the wonderful discussions, positive energy and dynamics. We hope you come back soon!
Nonlinear electrodynamics (NLE) is an umbrella term for various nonlinear generalisations of Maxwell’s theory, usually defined by Lagrangians depending on two quadratic electromagnetic invariants. We discuss two classes of no-go theorems that can be established when NLE fields are coupled to gravity.
On Wednesday 18, we gathered for a dinner in town to celebrate our many visitors. While Víctor Jaramillo (University of Science and Technology of China), Raimon Luna and Milton Ruiz (both from University of Valencia) joined us for a week, we also welcomed longer term guests Ana Bokulić (University of Zagreb) and Razieh Ranjbar (Ferdowsi University).
