Title: Haagerup Inequalities and Super-Additivity of the Regularized Minimum Output Entropy

Abstract: I will present some work of Collins-Youn on applications of the Haagerup inequality on free groups to the construction of quantum channels which witness super-addivity of the regularized minimum output entropy.

Title: Calabi-Yau Geometry of the Multiloop Sunset Feynman Integrals

Abstract: We will explore the "geometric gems" that emerge naturally when computing the simplest infinite family of Feynman integrals. These include Hessians of cubic surfaces, complete intersections in permutohedral varieties, and Landau-Ginzburg mirrors of weak Fano varieties. An iterative fibration structure on Calabi-Yau varieties, and a consequent iterative description of their periods, is ultimately crucial to understanding these Feynman integrals. We derive from this a conjectural "motivic mirror" principle that recasts Feynman integrals in terms of Landau-Ginzburg models fibered by motivic Calabi-Yau varieties.
