From bulk flows to boundary generators and costs
Rafael Carrasco, Carlos Pérez-Pardavila
Holographic complexity admits a broad family of bulk observables, yet their relation to boundary state-preparation costs remains unclear. We propose a local prescription that assoc…
Seeing Page Curves and Islands with Blinders On
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +3
This paper summarizes recent discussions of the Page curve and the information paradox, and responds to the reasoning and examples from arXiv:2506.04311. We review arguments demons…
Families of Hitchin Systems in Type-D
Aswin Balasubramanian, Jacques Distler, Ron Donagi +1
The Coulomb branch geometry of a 4d SCFT is encoded in the data of a complex integrable system. In class-S, this is the Hitchin System (of ADE type) on the puncture…
The Hitchin Image in Type-D
Aswin Balasubramanian, Jacques Distler, Ron Donagi +1
Motivated by their appearance as Coulomb branch geometries of Class S theories, we study the image of the local Hitchin map in tame Hitchin systems of type-D with residue in a spec…
Constraining braneworlds with entanglement entropy
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +4
We propose swampland criteria for braneworlds viewed as effective field theories of defects coupled to semiclassical gravity. We do this by exploiting their holographic interpretat…
Subregion Entropy for the Doubly Holographic Global Black String
Andreas Karch, Carlos Perez-Pardavila, Marcos Riojas +1
We study the growth of entanglement entropy in a doubly holographic model of gravity for a spherical AdS black hole. Compared to previous work, which was limited to the case of pla…
Entropy of Radiation with Dynamical Gravity
Carlos Perez-Pardavila
We compute the subregion entanglement entropy for a doubly holographic black string model. This system consists of a non-gravitating bath and a gravitating brane, where we incorpor…
Jackiw-Teitelboim Gravity from the Karch-Randall Braneworld
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +4
In this letter, we show that Jackiw-Teitelboim (JT) gravity can be naturally realized in the Karch-Randall braneworld. Notably the role of the dilaton in JT gravity is played by th…
Entanglement Phase Structure of a Holographic BCFT in a Black Hole Background
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +4
We compute holographic entanglement entropy for subregions of a BCFT thermal state living on a nongravitating black hole background. The system we consider is doubly holographic an…
Inconsistency of Islands in Theories with Long-Range Gravity
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +4
In ordinary gravitational theories, any local bulk operator in an entanglement wedge is accompanied by a long-range gravitational dressing that extends to the asymptotic part of th…
Information Transfer with a Gravitating Bath
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +4
Late-time dominance of entanglement islands plays a critical role in addressing the information paradox for black holes in AdS coupled to an asymptotic non-gravitational bath. A na…
