Large-c BCFT Entanglement Entropy with Deformed Boundaries from Emergent JT Gravity
Dominik Neuenfeld, Christopher Tellinger
We study the effect of boundary deformations on the von Neumann entropy of subregions in two-dimensional boundary conformal field theories (BCFTs) at zero and finite temperature. T…
The Flat-Space Limit of AdS Coupled to a Bath
Dominik Neuenfeld
We explain how to take a well-defined flat-space limit of brane models of AdS coupled to a non-gravitating bath. In the dual BCFT this amounts to a triple-scaling limit where both…
Real-Time Scattering in Ising Field Theory using Matrix Product States
Raghav G. Jha, Ashley Milsted, Dominik Neuenfeld +2
We study scattering in Ising Field Theory (IFT) using matrix product states and the time-dependent variational principle. IFT is a one-parameter family of strongly coupled non-inte…
Liouville gravity at the end of the world: Deformed defects in AdS/BCFT
Dominik Neuenfeld, Andrew Svesko, Watse Sybesma
We study shape deformations of two-dimensional end-of-the-world (ETW) branes, such as those in bottom-up models of two-dimensional holographic boundary conformal field theories (BC…
On the Causality Paradox and the Karch-Randall Braneworld as an EFT
Dominik Neuenfeld, Manu Srivastava
Holography on cutoff surfaces can appear to be in tension with causality. For example, as argued by Omiya and Wei [arxiv:2107.01219], double holography seemingly allows for superlu…
Bounds on gravitational brane couplings and tomography in AdS3 black hole microstates
Ji Hoon Lee, Dominik Neuenfeld, Ashish Shukla
We study information theoretic properties of planar black hole microstates in 2 + 1 dimensional asymptotically anti-de Sitter spacetime, modeled by black holes with an end-of-the-w…
The Dictionary for Double Holography and Graviton Masses in d Dimensions
Dominik Neuenfeld
Doubly-holographic models, also known as Karch-Randall brane worlds, have shown to be very useful for understanding recent developments around computing entropies in semi-classical…
Homology Conditions for RT Surfaces in Double Holography
Dominik Neuenfeld
Recently, a novel formula for computing entropy in theories coupled to semi-classical gravity has been devised. Using this so-called island formula the entropy of semi-classical bl…
Quantum Extremal Islands Made Easy, Part II: Black Holes on the Brane
Hong Zhe Chen, Robert C. Myers, Dominik Neuenfeld +2
We discuss holographic models of extremal and non-extremal black holes in contact with a bath in d dimensions, based on a brane world model introduced in arXiv:2006.04851. The main…
Quantum Extremal Islands Made Easy, Part I: Entanglement on the Brane
Hong Zhe Chen, Robert C. Myers, Dominik Neuenfeld +2
Recent progress in our understanding of the black hole information paradox has lead to a new prescription for calculating entanglement entropies, which involves special subsystems…
Soft photon theorems from CFT Ward identites in the flat limit of AdS/CFT
Eliot Hijano, Dominik Neuenfeld
S-matrix elements in flat space can be obtained from a large AdS-radius limit of certain CFT correlators. We present a method for constructing CFT operators which create incoming a…
Brane dynamics from the first law of entanglement
Sean Cooper, Dominik Neuenfeld, Moshe Rozali +1
In this note, we study the first law of entanglement in a boundary conformal field theory (BCFT) dual to warped AdS cut off by a brane. Exploiting the symmetry of boundary-centered…
Infrared-safe scattering without photon vacuum transitions and time-dependent decoherence
Dominik Neuenfeld
Scattering in 3+1-dimensional QED is believed to give rise to transitions between different photon vacua. We show that these transitions can be removed by taking into account off-s…
Positive gravitational subsystem energies from CFT cone relative entropies
Dominik Neuenfeld, Krishan Saraswat, Mark Van Raamsdonk
The positivity of relative entropy for spatial subsystems in a holographic CFT implies the positivity of certain quantities in the dual gravitational theory. In this note, we consi…
On the need for soft dressing
Daniel Carney, Laurent Chaurette, Dominik Neuenfeld +1
In order to deal with IR divergences arising in QED or perturbative quantum gravity scattering processes, one can either calculate inclusive quantities or use dressed asymptotic st…
Dressed infrared quantum information
Daniel Carney, Laurent Chaurette, Dominik Neuenfeld +1
We study information-theoretic aspects of the infrared sector of quantum electrodynamics, using the dressed-state approach pioneered by Chung, Kibble, Faddeev-Kulish and others. In…
Infrared quantum information
Daniel Carney, Laurent Chaurette, Dominik Neuenfeld +1
We discuss information-theoretic properties of low-energy photons and gravitons in the S-matrix. Given an incoming n-particle momentum eigenstate, we demonstrate that unobserved so…
