State-dressed local operators in the AdS/CFT correspondence
Eyoab Bahiru, Alexandre Belin, Kyriakos Papadodimas +2
We examine aspects of locality in perturbative quantum gravity and how information can be localized in subregions. In the framework of AdS/CFT, we consider the algebra of single-tr…
Gravitational path integral from the deformation
Alexandre Belin, Aitor Lewkowycz, Gabor Sarosi
We study a deformation of large conformal field theories, a higher dimensional generalization of the deformation. The deformed partition function satisfies a fl…
Entanglement versus entwinement in symmetric product orbifolds
Vijay Balasubramanian, Ben Craps, Tim De Jonckheere +1
We study the entanglement entropy of gauged internal degrees of freedom in a two dimensional symmetric product orbifold CFT, whose configurations consist of strands sewn togeth…
Chaos and relative entropy
Yuya O. Nakagawa, Gábor Sárosi, Tomonori Ugajin
One characterization of a chaotic system is the quick delocalization of quantum information (fast scrambling). One therefore expects that in such a system a state quickly becomes l…
AdS holography and the SYK model
Gábor Sárosi
These are lecture notes based on a series of lectures presented at the XIII Modave Summer School in Mathematical physics aimed at PhD students and young postdocs. The goal is to gi…
Modular Hamiltonians of excited states, OPE blocks and emergent bulk fields
Gábor Sárosi, Tomonori Ugajin
We study the entanglement entropy and the modular Hamiltonian of slightly excited states reduced to a ball shaped region in generic conformal field theories. We set up a formal exp…
Echoes of chaos from string theory black holes
Vijay Balasubramanian, Ben Craps, Bartłomiej Czech +1
The strongly coupled D1-D5 conformal field theory is a microscopic model of black holes which is expected to have chaotic dynamics. Here, we study the weak coupling limit of the th…
Relative entropy of excited states in conformal field theories of arbitrary dimensions
Gábor Sárosi, Tomonori Ugajin
Extending our previous work, we study the relative entropy between the reduced density matrices obtained from globally excited states in conformal field theories of arbitrary dimen…
Relative entropy of excited states in two dimensional conformal field theories
Gábor Sárosi, Tomonori Ugajin
We study the relative entropy and the trace square distance, both of which measure the distance between reduced density matrices of two excited states in two dimensional conformal…
