Toward a 3d Ising model with a weakly-coupled string theory dual (2020)
Journal Article
Iqbal, N., & McGreevy, J. (2020). Toward a 3d Ising model with a weakly-coupled string theory dual. SciPost Physics, 9(2), Article 019. https://doi.org/10.21468/scipostphys.9.2.019

It has long been expected that the 3d Ising model can be thought of as a string theory, where one interprets the domain walls that separate up spins from down spins as two-dimensional string worldsheets. The usual Ising Hamiltonian measures the area... Read More about Toward a 3d Ising model with a weakly-coupled string theory dual.

Bulk entanglement entropy for photons and gravitons in AdS$_3$ (2020)
Journal Article
Belin, A., Iqbal, N., & Kruthoff, J. (2020). Bulk entanglement entropy for photons and gravitons in AdS$_3$. SciPost Physics, 8(5), Article 075. https://doi.org/10.21468/scipostphys.8.5.075

We study quantum corrections to holographic entanglement entropy in AdS3/CFT2; these are given by the bulk entanglement entropy across the Ryu-Takayanagi surface for all fields in the effective gravitational theory. We consider bulk U(1) gauge fields... Read More about Bulk entanglement entropy for photons and gravitons in AdS$_3$.
