Journée de l’équipe GADT

René BaireI (IMB)

9h30-10h30 Théo MartyFlot de Reeb-Anosov en dimension 3Les flots d'Anosov représentent une famille importante de systèmes dynamiques (hyperbolique). Il existe plusieurs constructions de flots d'Anosov en dimension 3: suspension (hyperbolique), flot géodésique

Wolfgang Wieland: Quantum Geometry of the Light Cone

Recently, I introduced a non-perturbative quantization of impulsive gravitational null initial data. In this talk, I present the key results established thus far. The starting point is the characteristic null initial problem for tetradic gravity

Yoshihisa Saito: On elliptic root systems and their applications

Salle 318 (IMB) Salle 318 (IMB)

In the middle of 1980's, motivated by study of singularity theories, K. Saito introduced the notion of "elliptic root systems". Roughly speaking, they are root systems with two null directions. Furthermore, he

Volker Betz: The effective mass of the polaron

Salle 318 (IMB) Salle 318 (IMB)

The polaron describes a charged particle moving in a polarizable medium. Due to the interaction with the medium, the particle appears to be heavier that it would be outside the medium. This

COLLOQUIUM David Krejčiřík « Is the optimal rectangle a square? « 

Salle René Baire (IMB) Salle René Baire (IMB)

Speakers: David Krejčiřík (Czech Technical University in Prague)We give a light talk on optimality of shapes in geometry and physics. First, we recollect classical geometric results that the disk has the largest area (respectively,

Edward Mazenc: Strings From Feynman Diagrams

Salle 318 (IMB) Salle 318 (IMB)

How are bulk strings related to boundary Feynman diagrams? I will give an overview of my work with Rajesh Gopakumar on deriving the closed string dual to the simplest possible gauge theory,

Flash Talk session.

Please prepare a 5-minute talk on a topic of your choice. This could be related to your research, an object you are passionate about, or even a theorem statement.This is a wonderful

Lukas Müller: Topological defects

Salle 318 (IMB) Salle 318 (IMB)

Recently, the study of higher categories of topological defects in quantum field theory has gained significant attention due to their connection to categorical symmetries. These higher categories exhibit noteworthy additional structures, depending

Journée scientifique de l’IMB

amphi Bernard (UFR Sciences et Techniques)

Yu Hamada: Knotted comic strings in particle physics models

Salle 318 (IMB) Salle 318 (IMB)

Cosmic strings (or vortex strings) are topological defects arising when U(1) symmetry is spontaneously broken in quantum field theories. In three-dimensional relativistic systems, loops of cosmic strings are known to be unstable
