Complexity and the bulk volume, a new York time story
Alexandre Belin, Aitor Lewkowycz, Gabor Sarosi
We study the boundary description of the volume of maximal Cauchy slices using the recently derived equivalence between bulk and boundary symplectic forms. The volume of constant m…
The boundary dual of the bulk symplectic form
Alexandre Belin, Aitor Lewkowycz, Gábor Sárosi
In this paper, we study the overlaps of wavefunctionals prepared by turning on sources in the Euclidean path integral. For nearby states, these overlaps give rise to a Kahler struc…
Siegel Paramodular Forms and Sparseness in AdS/CFT
Alexandre Belin, Alejandra Castro, Joao Gomes +1
We discuss the application of Siegel paramodular forms to the counting of polar states in symmetric product orbifold CFTs. We present five special examples and provide exact analyt…
Bulk entanglement entropy in perturbative excited states
Alexandre Belin, Nabil Iqbal, Sagar F. Lokhande
We compute the bulk entanglement entropy across the Ryu-Takayanagi surface for a one-particle state in a scalar field theory in AdS. We work directly within the bulk Hilbert sp…
Comments on a state-operator correspondence for the torus
Alexandre Belin, Jan de Boer, Jorrit Kruthoff
We investigate the existence of a state-operator correspondence on the torus. This correspondence would relate states of the CFT Hilbert space living on a spatial torus to the path…
