Cours du LPTMS : Raoul Santachiara

Cours du LPTMS Introduction to Conformal Field Theory The conformal field theory (CFT) approach aims to find the solutions of the infinite set of equations imposed by conformal invariance. This approach has been successfully employed in diverse areas of physics and mathematics for almost thirty years. We will survey the basics ideas of the CFT …

Séminaire du LPTMS: Ian McCulloch

Topological insulating phase in the molecular compound $mathrm{Mo_3 S_7 (dmit)_3}$ Ian McCulloch (University of Queensland, Australie) Using the infinite-size density matrix renormalization group (iDMRG) approach, we show that a Hubbard-like model on a triangular cluster, representative of the compound $mathrm{Mo_3 S_7 (dmit)_3}$, is in the universally class of the symmetry-protected topological 1D Haldane insulator, despite …

Tri-séminaire de Physique Statistique : Vincent Vargas

Complex Gaussian multiplicative Chaos Vincent VARGAS (Dépt. de Mathématique (DMA), Ecole Normale Supérieure Paris)  The mathematical theory of Gaussian multiplicative chaos was founded by J. P. Kahane in 1985. This theory has numerous applications in mathematical physics: 2d Liouville quantum gravity in the conformal gauge (boundary and non boundary Liouville measure, KPZ equation), the Kolmogorov-Obukhov …
