Journal Article

We compute the bulk entanglement entropy across the Ryu-Takayanagi surface for a oneparticle state in a scalar field theory in AdS3. We work directly within the bulk Hilbert space and include the spatial spread of the scalar wavefunction. We give clo... Read More about Bulk entanglement entropy in perturbative excited states.

Wilson lines and Ishibashi states in AdS3/CFT2 (2018)

We provide a refined interpretation of a gravitational Wilson line in AdS3 in terms of Ishibashi states in the dual CFT2. Our strategy is to give a method to evaluate the Wilson line that accounts for all the information contained in the representati... Read More about Wilson lines and Ishibashi states in AdS3/CFT2.

Generalized global symmetries and holography (2018)
Journal Article
Hofman, D., & Iqbal, N. (2018). Generalized global symmetries and holography. SciPost Physics, 4(1), Article 005. https://doi.org/10.21468/scipostphys.4.1.005

We study the holographic duals of four-dimensional field theories with 1-form global symmetries, both discrete and continuous. Such higher-form global symmetries are associated with antisymmetric tensor gauge fields in the bulk. Various different rea... Read More about Generalized global symmetries and holography.
