Speakers: Erwan Allys (LPENS Paris) New statistical descriptions related to the so-called Scattering Transform recently obtained attractive results for several astrophysical applications. These statistics share ideas with convolutional neural networks, but do not require to be learned, allowing for very efficient characterization of non-Gaussian processes from a very small amount of data. In this talk, […]

Speakers: Diego Guadagnoli (LAPTh Annecy), Ludovico Vittorio (LAPTh, Université Savoie Mont-Blanc and CNRS, Annecy, France) Teacher: Balasubramanian Ananthanarayan (Anant), Bangalore, Indian Inst. Sci. Language: English Summary The course is placed at the interface between particle physics and mathematical physics. It is addressed to PhD-level students, and aims at introducing, in a self-contained way, fundamental concepts […]

Speakers: Jakob Moritz (CERN) . Abstract: The simplest cosmology compatible with the accelerated expansion of our universe is de Sitter space. Yet, more than 25 years after the discovery of ``dark energy’’, concrete de Sitter vacua of string theory have remained elusive. In this talk I will present the first fully concrete string compactifications that yield, […]

Speakers: Paolo Creminelli (ICTP, Trieste) The coefficients of the operators of an effective field theory (EFT) are constrained to satisfy certain inequalities, under the (mild) assumption that the UV completion satisfies general requirements of causality and unitarity. I discuss the extension of these ideas to theories where the Lorentz symmetry is spontaneously broken, as it […]

This is the 5th instance of the in-person AnLy meetings between neighboring institutions (IP2I Lyon, LAPTh Annecy, LPENSL Lyon) on string and field theory topics. It will take place at ENS Lyon, room MGN1-103 (1st floor, research side), on the 03rd December 2024.   Travel: Options between Lyon and Annecy are train (or train + bus), […]

Speakers: Gilles Parez As you may know, my research interests lie at the intersection of integrable systems and quantum information. This JC will be the occasion for me to give a *literal* introduction to the latter.  Many papers (and grant proposal) about quantum information and quantum entanglement in many-body systems contain a version of the […]

Speakers: Gilles Parez (Lapth) Many papers (and grant proposal) about quantum information and quantum entanglement in many-body systems contain a version of the following sentence in their introduction: "It is very efficient to use quantities originally defined in the context of quantum information, such as entanglement measures, to detect and characterize quantum phase transitions in […]

Speakers: Philippe Brax (CEA) . Abstract: I will review the problems caused by light scalar fields in particular with respect to gravitational tests and consider a new type of screening mechanism which allows to evade them. This involves two fields, an axion-like field and a dilaton, for which I will also present new results on their […]

Speakers: Christophe Grojean (DESY (Hamburg) and Humboldt University (Berlin)) Le futur collisionneur circulaire se profile comme le prochain grand défi scientifique à relever. Son programme ambitieux devrait occuper la physique des hautes énergies pour les décennies à venir.  Qu'il s'agisse d’explorer le modèle standard avec une précision sans précédent ou de rechercher de nouvelles particules, […]
