“The Holographic Mystique”

In the recent years, there has been a remarkable proliferation of the holographic techniques originating from ‘bona fide’ string theory into a number of other fields, including condensed matter. This emergent confluence of ideas from high energy, gravity, quantum information, and many-body theory has become a new frontier where some of the most challenging fundamental questions are being addressed. However, many of the current condensed mater-related holographic applications remain deeply controversial and their true status is yet to be ascertained. In this talk I’ll review the state of the field, focusing on a few condensed matter examples of analogue holography (flexible graphene and optical metamaterials) as well as its soluble (Sachdev-Ye-Kitaev and Witten-Gurau) toy models.
