Cost functionals for holographic complexity

Friday, April 12, 2024 - 15:00 to 16:00
Hall A, Arts Block, North Campus, Maynooth and on Teams


The Department of Theoretical Physics welomes Dr. Sergio Hoertner (Luxembourg) to give his talk on Cost functionals for holographic complexity

Complexity has been introduced in the holographic dictionary as a dual descriptor of the growth of the Einstein-Rosen bridge in the interior of a black hole long after thermalization. Several proposals relating boundary complexity to the bulk geometry have been constructed, most notably based on bulk volume and action. We present a framework for the discussion of holographic complexity based on cost functionals. Connections with TTbar deformations and spin chains will be highlighted.
