Bertrand Eynard, Paolo Gregori, Dimitrios Mitsios and Soufiane Oukassi from the IPhT are among the organisers of the August 2024 session (29 July - 23 August) of the prestigious "Les Houches" International School of Physics. The Les Houches Quantum Geometry School (Mathematical methods for gravity, gauge theories and non-perturbative physics) will bring together leading experts in theoretical physics. It will offer to 50 students from all over the world introductory courses covering topics such as quantum gravity, gauge theories and non-perturbative physics. These courses will focus on the methods of mathematical physics, in particular the theory of random matrices, topological recurrence, resurgence and moduli space. This event is part of the ERC-SyG Project ReNewQuantum.   School website : https://houches24.github.io/

Since the 1980s, many exact results have been discovered in 2d CFT, from critical exponents to correlation functions to complete solutions of certain models. In d>2, there is a wealth of numerical results as well as promising analytic approaches, but comparably fewer exact answers. The aim of this conference is to review the most promising analytic methods and results in CFT in any dimension. In particular we will try to understand to which extent the 2d methods can be extended to d>2, and what is missing to exactly solve d>2 CFTs. Speakers: Fernando Alday Colin Guillarmou Yifei He Gregory Korchemsky Petr Kravchuk Elli Pomoni Ingo Runkel  Hubert Saleur Volker Schomerus Xin Sun Emilio Trevisani Philine van Vliet Registration: The conference is in person only, and limited to 45 participants, who are supposed to attend all the talks. People who would like to participate should fill the registration form no later than June 10th.

The Institute of Theoretical Physics (IPhT), formerly SPhT, is internationally known for the excellence of its scientific research, but has also a very ancient history. Its evolution is inextricably linked to that of the CEA and is almost as old. Its adventure began in 1947 with a small group of physicians passionated for abstraction, and to date more than 500 people have shared the life of the Institute, as well as the many visitors from all over the world. Today, 48 permanent researchers, 25 graduate students and 30 postdoctoral fellows, as well as the support staff, work at IPhT.

The retreat of the Institute of Theoretical Physics was held in Autrans (Vercors) from May 23 to 25. The approximately one hundred participants enjoyed the benefits of the altitude and the gorgeous environment surrounding the Escandille congress center, which hosted the event. This intense and joyful retreat provided an opportunity to strengthen the cohesion between members of our laboratory and to discuss among ourselves issues of science and the life of the Institute. The IPhT is characterized by a broad spectrum of research topics. In order to highlight the skills and to pedagogically transmit the knowledge to other non-expert colleagues, 7 scientific presentations of IPhT researchers were organized, complemented by 2 presentations held by external speakers, Professors Luc Blanchet (Institut d'Astrophysique de Paris, long-term visitor at IPhT) and Emil Martinec (University of Chicago).

In the past 10 years, the French community working on maps on surfaces has come together several times per year during the so-called "maps days".

La description microscopique des trous noirs est un défi depuis plus de quarante ans. Il existe aujourd'hui un certain nombre d'approches prometteuses pour résoudre ce problème et l'objectif principal de cette conférence et de ce workshop est de réunir des experts dans ces domaines afin d'identifier les synergies, de s'engager dans une critique constructive et de résoudre les conflits apparents. Une attention particulière sera accordée à la dynamique de la microstructure des trous noirs : comment la matière entrante est brouillée et comment l'information est récupérée. La conférence se tiendra seulement en ligne le lundi 6 juin (jour férié en France) puis en personne à l'IPhT, CEA-Saclay du mardi 7 au vendredi 10 juin. Chaque jour de la conférence sera également retransmis. Inscription sur le site web.

Thermalization and out of equilibrium dynamics of many body strongly interacting quantum systems have been the subject of a recent burst of research activities. In particular the dynamics of operator and information spreading (scrambling) as well as its chaotic behavior have been recently investigated starting from models originated in the context of strongly correlated many body systems and have found application to black holes physics. This has been triggered by the appearance of a new class of exactly soluble large N quantum field theories, such as the celebrated Sachdev-Ye-Kitaev model. The aim of this workshop is to review the recent advances in the field and to stimulate further research in this direction which lies at the interface between statistical and condensed matter physics and high-energy/mathematical physics. Due to the current situation, the conference will take place online.
