Boundaries in Free Higher Derivative Conformal Field Theories
Adam Chalabi, Christopher P. Herzog, Krishnendu Ray +3
We consider free higher derivative theories of scalars and Dirac fermions in the presence of a boundary in general dimension. We establish a method for finding consistent conformal…
Weyl Anomalies of Four Dimensional Conformal Boundaries and Defects
Adam Chalabi, Christopher P. Herzog, Andy O'Bannon +2
Motivated by questions about quantum information and classification of quantum field theories, we consider Conformal Field Theories (CFTs) in spacetime dimension with a c…
Islands in Multiverse Models
Sergio E. Aguilar-Gutierrez, Aidan Chatwin-Davies, Thomas Hertog +2
We consider multiverse models in two-dimensional linear dilaton-gravity theories as toy models of false vacuum eternal inflation. Coupling conformal matter we calculate the Von Neu…
Monodromy Defects in Free Field Theories
Lorenzo Bianchi, Adam Chalabi, Vladimír Procházka +2
We study co-dimension two monodromy defects in theories of conformally coupled scalars and free Dirac fermions in arbitrary dimensions. We characterise this family of conformal…
Kaluza-Klein Spectroscopy for the Leigh-Strassler SCFT
Nikolay Bobev, Emanuel Malek, Brandon Robinson +2
We apply recently developed tools from exceptional field theory to calculate the full Kaluza-Klein spectrum of the AdS Pilch-Warner solution of type IIB supergravity. Through t…
Central Charges of 2d Superconformal Defects
Adam Chalabi, Andy O'Bannon, Brandon Robinson +1
In conformal field theories (CFTs) of dimension , two-dimensional (2d) conformal defects are characterised in part by central charges defined via the defect's contribution to…
Partial-Symmetry-Breaking Phase Transitions
Masanori Hanada, Brandon Robinson
We demonstrate a novel feature of certain phase transitions in theories with large rank symmetry group that exhibit specific types of non-local interactions. A typical example of s…
From the Weyl Anomaly to Entropy of Two-Dimensional Boundaries and Defects
Kristan Jensen, Andy O'Bannon, Brandon Robinson +1
We study whether the relations between the Weyl anomaly, entanglement entropy (EE), and thermal entropy of a two-dimensional (2D) conformal field theory (CFT) extend to 2D boundari…
Wilson Surface Central Charge from Holographic Entanglement Entropy
John Estes, Darya Krym, Andy O'Bannon +2
We use entanglement entropy to define a central charge associated to a two-dimensional defect or boundary in a conformal field theory (CFT). We present holographic calculations of…
Boundary and Defect CFT: Open Problems and Applications
Natan Andrei, Agnese Bissi, Matthew Buican +18
Proceedings of the workshop "Boundary and Defect Conformal Field Theory: Open Problems and Applications," Chicheley Hall, Buckinghamshire, UK, 7-8 Sept. 2017.
Master 3d Bosonization Duality with Boundaries
Kyle Aitken, Andreas Karch, Brandon Robinson
We establish the action of the three-dimensional non-Abelian bosonization dualities in the presence of a boundary, which supports a non-anomalous two-dimensional theory. In particu…
Deconstructing S-Duality
Kyle Aitken, Andreas Karch, Brandon Robinson
We use the technique of deconstruction to lift dualities from 2+1 to 3+1 dimensions. In this work we demonstrate the basic idea by deriving S-duality of maximally supersymmetric el…
3d Abelian Dualities with Boundaries
Kyle Aitken, Andrew Baumgartner, Andreas Karch +1
We establish the action of three-dimensional bosonization and particle-vortex duality in the presence of a boundary, which supports a non-anomalous two-dimensional theory. We confi…
Supersymmetric D3/D5 for massive defects on curved space
Brandon Robinson, Christoph F. Uhlemann
We construct the holographic dual for SYM on and coupled to massive supersymmetric quenched flavor fields on a codimension-1 def…
More Abelian Dualities in 2+1 Dimensions
Andreas Karch, Brandon Robinson, David Tong
We expand on the recent derivation of 3d dualities using bosonization. We present in some detail a general class of Abelian duals.
Holographic Black Hole Chemistry
Andreas Karch, Brandon Robinson
Thermodynamic quantities associated with black holes in Anti-de Sitter space obey an interesting identity when the cosmological constant is included as one of the dynamical variabl…
A Precision Test of AdS/CFT with Flavor
Andreas Karch, Brandon Robinson, Christoph F. Uhlemann
In this letter we put AdS/CFT dualities involving probe branes to a precision test. On the holographic side we use a new class of supersymmetric D7-brane embeddings into AdS$_5\tim…
Supersymmetric D3/D7 for holographic flavors on curved space
Andreas Karch, Brandon Robinson, Christoph F. Uhlemann
We derive a new class of supersymmetric D3/D7 brane configurations, which allow to holographically describe N=4 SYM coupled to massive N=2 flavor degrees of freedom on spaces of co…
The holographic dual of a Hawking pair has a wormhole
Kristan Jensen, Andreas Karch, Brandon Robinson
In previous work, two of us constructed the holographic dual of a single Einstein-Podolsky-Rosen (EPR) pair in maximally supersymmetric Yang-Mills theory. Here we extend that work…
