String Theory and Holographic Duality
Course Description
This string theory course focuses on holographic duality (also known as gauge / gravity duality or AdS / CFT) as a novel method of approaching and connecting a range of diverse subjects, including quantum gravity / black holes, QCD at extreme conditions, exotic condensed matter systems, and quantum information.

Illustration of how cows at different distances in the bulk correspond to cows of different sizes at a boundary with illustrative text
In holographic duality, a quantum gravity system in a (d+1)-dimensional spacetime is equivalent to a many-body system defined on its d-dimensional boundary. The boundary system is referred to as a “hologram” of the bulk system. For more information about this image, see the syllabus section. (Image by Prof. Liu.)
