Holographic complexity with TT deformation — •Souvik Banerjee, Johanna Erdmenger, and Emma Loos — Julius-Maximilians-University Würzburg, Würzburg, Germany

TT deformed CFTs are dual to semiclassical gravity in AdS spacetime with a finite radial cutoff. Complexity of boundary CFT operators, on the other hand, has an intimate connection to radial depth in the bulk. The duality between TT deformed CFTs and gravitational physics at a cut off AdS spacetime will therefore be an ideal playground to test holographic proposals for complexity. This also helps in understanding quantitatively and explicitly, the renormalization group flow in the bulk and thereby explaining the emergence of AdS spacetime in the tensor network like cMERA.
