Quenched vs Annealed: Glassiness from SK to SYK
C. L. Baldwin, B. Swingle
Abstract
The Sachdev-Ye-Kitaev model of interacting fermions is a powerful tool for studying quantum gravity. A new analysis identifies spin-glass physics in any local version of the model, raising the question of whether quantum gravity requires fermions.
