Hessian Matching for Machine-Learned Coarse-Grained Molecular Dynamics
Sanya Murdeshwar, Sanjit Shashi, Kevin Bachelor +3
Coarse-grained (CG) molecular dynamics enables simulations of atomic systems such as biomolecules at timescales inaccessible to all-atom (AA) methods, but existing CG neural potent…
Holographic generative flows with AdS/CFT
Ehsan Mirafzali, Sanjit Shashi, Sanya Murdeshwar +3
Holography, in the form of the anti-de Sitter/conformal field theory (AdS/CFT) correspondence, offers a natural setting for generative modelling. Data on a boundary manifold lifts…
Thermal effective actions from conformal boundary conditions in gravity
Batoul Banihashemi, Edgar Shaghoulian, Sanjit Shashi
Recent work has studied the thermodynamics of gravity subjected to conformal boundary conditions, where the trace of the extrinsic curvature and the conformal class of metrics…
Background ambiguity and the Gödel double copy
Brian Kent, Tucker Manton, Sanjit Shashi
In this work, we investigate the assumptions regarding spacetime backgrounds underlying the classical double copy. We argue (contrary to the norm) that single-copy fields naturally…
Flat space gravity at finite cutoff
Batoul Banihashemi, Edgar Shaghoulian, Sanjit Shashi
We study the thermodynamics of Einstein gravity with vanishing cosmological constant subjected to conformal boundary conditions. Our focus is on comparing the series of subextensiv…
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…
Imprints of phase transitions on Kasner singularities
Elena Caceres, Sanjit Shashi, Hao-Yu Sun
Under the AdS/CFT correspondence, asymptotically AdS geometries with backreaction can be viewed as CFT states subject to a renormalization group (RG) flow from an ultraviolet (UV)…
Transport across interfaces in symmetric orbifolds
Saba Asif Baig, Sanjit Shashi
We examine how conformal boundaries encode energy transport coefficients -- namely transmission and reflection probabilities -- of corresponding conformal interfaces in symmetric o…
Scrambling in quantum cellular automata
Brian Kent, Sarah Racz, Sanjit Shashi
Scrambling is the delocalization of quantum information over a many-body system and underlies all quantum-chaotic dynamics. We employ discrete quantum cellular automata as classica…
Holographic BCFT Spectra from Brane Mergers
Shovon Biswas, Jani Kastikainen, Sanjit Shashi +1
We use holography to study the spectra of boundary conformal field theories (BCFTs). To do so, we consider a 2-dimensional Euclidean BCFT with two circular boundaries that correspo…
Anisotropic Flows into Black Holes
Elena Caceres, Sanjit Shashi
We consider anisotropic black holes in the context of holographic renormalization group (RG) flows. We construct an -function that is stationary at the boundary and the horizon…
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…
Trans-IR Flows to Black Hole Singularities
Elena Caceres, Arnab Kundu, Ayan K. Patra +1
We study analytic continuations of holographic renormalization group (RG) flows beyond their infrared (IR) fixed points. Such "trans-IR" flows are a natural framework for describin…
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…
Structure of Holographic BCFT Correlators from Geodesics
Jani Kastikainen, Sanjit Shashi
We compute correlation functions, specifically 1-point and 2-point functions, in holographic boundary conformal field theory (BCFT) using geodesic approximation. The holographic mo…
Circuit Complexity in Topological Quantum Field Theory
Josiah Couch, Yale Fan, Sanjit Shashi
Quantum circuit complexity has played a central role in recent advances in holography and many-body physics. Within quantum field theory, it has typically been studied in a Lorentz…
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…
Page Curves and Bath Deformations
Elena Caceres, Arnab Kundu, Ayan K. Patra +1
We study the black hole information problem within a semiclassically gravitating AdS black hole coupled to and in equilibrium with a -dimensional thermal conformal bath. We…
Warped Information and Entanglement Islands in AdS/WCFT
Elena Caceres, Arnab Kundu, Ayan K. Patra +1
We use the notion of double holography to study Hawking radiation emitted by the eternal BTZ black hole in equilibrium with a thermal bath, but in the form of warped CFT degree…
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…
Quotient-AdS/BCFT: Holographic Boundary CFT on AdS Quotients
Sanjit Shashi
The holographic principle, being a generic feature of quantum gravity, should allow for the consideration of dualities other than AdS/CFT. The AdS/BCFT correspondence, in which the…
A Killing Vector Treatment of Multiboundary Wormholes
Elena Caceres, Arnab Kundu, Ayan K. Patra +1
The two-sided BTZ black hole has been instrumental in elucidating several aspects of AdS/CFT. Similarly, multiboundary wormholes provide a useful and rich arena in which probing qu…
