Revisiting non-relativistic limits
AbstractWe show that the full spurionic symmetry of Galilean-invariant field theories can be deduced when those theories are the limits of relativistic parents. Under the limit, the non-relativistic...
View ArticleUniversal entanglement and boundary geometry in conformal field theory
AbstractEmploying a conformal map to hyperbolic space cross a circle, we compute the universal contribution to the vacuum entanglement entropy (EE) across a sphere in even-dimensional conformal field...
View ArticleBosonizing three-dimensional quiver gauge theories
AbstractWe start with the recently conjectured 3d bosonization dualities and gauge global symmetries to generate an infinite sequence of new dualities. These equate theories with non-Abelian product...
View ArticleEmbedding three-dimensional bosonization dualities into string theory
AbstractWe give simple string theory embeddings of several recently introduced dualities between 2+1-dimensional Chern-Simons matter theories using probe brane holography. Our construction is reliable...
View ArticleLocality and anomalies in warped conformal field theory
AbstractWe study various aspects of warped conformal field theories (WCFTs) in two dimensions. We find new Lagrangian WCFTs, and show that all known Lagrangian WCFTs are local only after an infinite...
View ArticleA master bosonization duality
AbstractWe conjecture a new sequence of dualities between Chern-Simons gauge theories simultaneously coupled to fundamental bosons and fermions. These dualities reduce to those proposed by Aharony when...
View Article’t Hooft anomalies and boundaries
AbstractWe argue that there is an obstruction to placing theories with ’t Hooft anomalies on manifolds with a boundary, unless the symmetry associated with the anomaly can be represented as a...
View ArticleDissipative hydrodynamics in superspace
AbstractWe construct a Schwinger-Keldysh effective field theory for relativistic hydrodynamics for charged matter in a thermal background using a superspace formalism. Superspace allows us to...
View ArticleAn entropy current in superspace
AbstractWe provide a mechanism by which an entropy current can be constructed in a supersymmetric formulation of the low-energy effective action for the Schwinger-Keldysh generating functional. This...

AbstractWe rewrite the Chern-Simons description of pure gravity on global AdS3 and on Euclidean BTZ black holes as a quantum field theory on the AdS boundary. The resulting theory is (two copies of)...

AbstractWe study U(N )k Chern-Simons theory coupled to fundamental fermions and scalars in a large N‘t Hooft limit. We compute the thermal free energy at high temperature, as well as two- and...

AbstractWe compute the path integral of three-dimensional gravity with negative cosmological constant on spaces which are topologically a torus times an interval. These are Euclidean wormholes, which...

AbstractIt has long been known that the coarse-grained approximation to the black hole density of states can be computed using classical Euclidean gravity. In this work we argue for another entry in...

AbstractWe reconsider the role of wormholes in the AdS/CFT correspondence. We focus on Euclidean wormholes that connect two asymptotically AdS or hyperbolic regions with 𝕊1× 𝕊d−1 boundary. There is no...

AbstractWe consider quantum algebras of observables associated with subregions in theories of Einstein gravity coupled to matter in the GN→ 0 limit. When the subregion is spatially compact or...
