However\, we still don’t understand why these formulas are true from a canonical point of view. In this talk\, I will attempt to make progress on this problem by developing an analogy between gravitation al entropy formulas in low-dimensional examples of holography and similar- looking formulas that have appeared in the study of entanglement entropy i n emergent gauge theories. This talk will be based on 1807.06575\, 2107.11 872\, and 2107.12634.\n LOCATION:https://researchseminars.org/talk/HET/19/ END:VEVENT END:VCALENDAR
