Final Report Summary - SPIN (Symmetry Principles in Nature)
We used general symmetry principles to guide us in understanding holographic models; we in particular argued that a class of permutation orbifolds provides a clear prototype for the gauge/gravity correspondence. We also explored how entanglement structures in holographic theories may be constrained.
We also examined hydrodynamic effective field theories as part of our goal of understanding non-equilibrium dynamics in QFT. We have demonstrated that the considerations of microscopic unitarity and macroscopic manifestation of the second law of thermodynamics to be consequences of an emergent thermal gauge symmetry. This is perhaps the most important results derived in the course of the project.
