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

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

Antonino Flachi: Revisiting the Quantum Vacuum

Salle 318 (IMB) Salle 318 (IMB)

A fundamental prediction of quantum physics is the existence of random fluctuations everywhere in vacuum. This is one of the most remarkable and central ideas in quantum field theory which manifests itself

Jules Lamers: An invitation to long-range quantum integrability

Salle 318 (IMB) Salle 318 (IMB)

Spin chain are quantum-mechanical models for magnetic materials. Special examples are (quantum) integrable: they have many conserved charges whose spectrum can be determined exactly thanks to a rich underlying algebraic structure. While
