Miðbiksmat/Midway evaluation: Alexia Nix

Speaker: Alexia Nix, University of Iceland Date: October 18 Time: 15.00 Place: VRII-156 Title: Wilson loops and precision holography Abstract: The main objective of this talk is the study of holography beyond the conformal paradigm. A specific example of this is realized through the study of 1/2-BPS Wilson loops in maximally supersymmetric Yang-Mills theories on […]

Miðbiksmat/Midway evaluation: Vyshnav Mohan

Speaker: Vyshnav Mohan Date: October 16 Time: 13.00 Place: Oddi-203 Title: Complexity, Bulk Reconstruction, and Semiclassical Black Holes Abstract:  Quantum computational complexity is an information-theoretic measure that probes the finer details of the Hilbert space of a quantum system. We will study two of its avatars: Krylov complexity and holographic complexity. We will then show

Miðbiksmat/Midway evaluation: Evangelos Tsolakidis

Speaker: Evangelos Tsolakidis Time and Place: September 16, kl. 13.20, VRII-138 Title: Deformations and Gauge Fields Abstract: Deformations of Quantum Field Theories are an essential tool in our collective attempt to understand the fundamental nature of our universe. They correspond to the so-called interaction terms of a theory, and affect experimentally measurable quantities. In this

Midway evaluation, Daniel Amankwah

Room: Via Zoom. Link to be sent.Time: Friday, December 11, at 10:00. Doctoral student: Daniel Amankwah Project title: Scaling limits of random, face-weighted, tree like planar maps. Project description: The doctoral project lies in the scope of random planar maps. We investigate scaling limits of various classes of discrete planar maps which are by construction “tree-like”.
