The Paris-Saclay AstroParticle Symposium 2019 has begun at the Institute Pascal
The 2019 AstroPascal workshop on astroparticles is taking place place at the Pascal Institute of the Paris-Saclay University. It is organized by Philippe Brax of IPhT and Yann Mambrini of LPT-Orsay.
Around 30 specialists of astrophysics, cosmology and particle physics will be invited to discuss and work on the themes: Dark Energy and Dark Matter. The format will be flexible enough to allow for strong interactions between participants. There will be working sessions every day and on Fridays, a « conference » format day with invited speakers. We have invited confirmed researchers and are strongly encouraging the presence of their students and/or postdocs. The ultimate aim is to initiate-continue-finalise research projects in a nice environment.
Programme (14th October - 8th November 2019)
First week: Cosmology after GW170817
Second Week: Dark energy where art thou?
Third week: WIMP Dark Matter and its many guises
Fourth week: Beyond the WIMP paradigm?
Bertrand Eynard est un physicien théoricien, qui après une thèse sur les matrices aléatoires (sous la direction de Jean Zinn-Justin), est devenu chercheur au CEA (Commissariat à l'énergie atomique et aux énergies renouvelables) depuis 1995. Ses travaux ont d'abord porté sur les matrices aléatoires où il a apporté d'importantes contributions et écrit et enseigné plusieurs cours. En 2004, il a introduit une nouvelle méthode algébrique pour le calcul du développement asymptotique des matrices aléatoires de grande taille, appelée la "récurrence topologique".
Cette méthode a connu un grand succès car elle s'est trouvée être bien plus générale que les matrices aléatoires: elle apparaît dans de très nombreux domaines de la physique mathématiques, comme la géométrie énumérative, les invariants de Gromov-Witten, la théorie des noeuds, la théorie des cordes et les systèmes intégrables. La récurrence topologique est devenue un sujet mathématique à part entière, enseigné en master et faisant l'objet de plusieurs conférences annuelles. Conjointement avec M. Kontsevich, B. Eynard a été lauréat en 2019 de la bourse européenne ERC synergie pour le projet ReNewQuantum, portant principalement sur l'étude de la récurrence topologique et de ses développements. Toutes nos félicitations à Bertrand !
We are pleased to learn that Lenka Zdeborovà, CNRS researcher at IPhT, has just been awarded the Irène Joliot-Curie "Young Woman Scientist" prize for the year 2018.
The Irène Joliot-Curie Awards are intended to promote women's place in research and technology in France. They are awarded by the Ministry of Higher Education, Research and Innovation and Airbus with the support of the Academy of Sciences and the Academy of Technology.
Lenka is interested in applications of methods developed in statistical physics, such as advanced mean-field methods, replica method and message passing algorithms, for problems in machine learning and artificial intelligence, signal processing, inference and optimization. In other words: what are the problems that can be solved effectively using a computer? If this question is traditionally addressed in the fields related to informatics, she approaches it from the point of view of statistical physics. Theoretical methods of analysis, developed in the statistical physics of disordered systems, are indeed able to provide results and understanding beyond the state of the art existing in mathematics, computer science or statistics.
Congratulations Lenka!
