IAS High Energy Theory Seminar
Topic: Magic and Wormholes
Speaker: Brian SwingleAffiliation: Brandeis University
Date: March 23, 2026 2:30pm
Bloomberg Lecture Hall (IAS) & Zoom
I will discuss the quantum resource known as magic and its analysis in many-fermion systems such as the Sachdev-Ye-Kitaev model. I will show that the SYK calculation of magic can be quantitatively modeled with a gravity calculation involving wormhole geometries in JT gravity coupled to matter. I will also discuss how these results relate to recent holographic models of closed universes.
Based on arxiv.org/abs/2602.12339 with Valerie Bettaque and arxiv.org/abs/2512.00149 with Martin Sasieta and Alejandro Vilar-Lopez.
