Titill: Field theory compositeness, holographic gravity and higher spins

Ágrip:

I would like to discuss the idea that composite operators in field theory
are key ingredients in holograms of bulk gravitational physics. In practice,
this is well known: Composites are essential in both matrix (Maldacena) and vector (Klebanov-Polyakov) AdS/CFT. I argue that composite correlators in thermal and quenched field theory backgrounds illuminate the importance of compositeness further. They behave as boundary-boundary correlators in geometries with a strong gravitational source in the interior, whether the bulk is Einsteinian or higher spin-like.
