A Holographic Map from AdS to CFT
Manish Ramchander, Ronak M Soni
We propose a holographic map from the semiclassical Hilbert space of pure general relativity in to that of . We define the bulk Hilbert space by se…
Emergent Area Operators in the Boundary
Ronak M Soni
In some cases in two and three bulk dimensions without bulk local degrees of freedom, I look for area operators in a fixed boundary theory. In each case, I define an exact quantum…
Minimal Areas from Entangled Matrices
Jackson R. Fliss, Alexander Frenkel, Sean A. Hartnoll +1
We define a relational notion of a subsystem in theories of matrix quantum mechanics and show how the corresponding entanglement entropy can be given as a minimisation, exhibiting…
A New Covariant Entropy Bound from Cauchy Slice Holography
Ronak M Soni, Aron C. Wall
We begin an investigation of a new holographic covariant entropy bound (HCEB) in gravity. This bound arises from Cauchy slice holography, a recently proposed duality between the bu…
Multipartite edge modes and tensor networks
Chris Akers, Ronak M. Soni, Annie Y. Wei
Holographic tensor networks model AdS/CFT, but so far they have been limited by involving only systems that are very different from gravity. Unfortunately, we cannot straightforwar…
Extremality as a Consistency Condition on Subregion Duality
Ronak M Soni
In JT gravity coupled to a CFT, I argue without using the path integral that the entanglement wedge of a boundary region is bounded by a quantum extremal surface (QES). For any can…
A Type Approximation of the Crossed Product
Ronak M Soni
I show that an analog of the crossed product construction that takes type algebras to type algebras exists also in the type case. This is particularly natural wh…
Boundary Description of Microstates of the Two-Dimensional Black Hole
Amr Ahmadain, Alexander Frenkel, Krishnendu Ray +1
We identify the microstates of the non supersymmetric, asymptotically flat 2d black hole in the dual c=1 matrix quantum mechanics (MQM). We calculate the partition function of the…
On the Spread of Entanglement at Finite Cutoff
Evan Coleman, Ronak M Soni, Sungyeon Yang
We study how entanglement spreads in the boundary duals of finite-cutoff three-dimensional theories with positive, negative and zero cosmological constant, the …
de Sitter Microstates from and the Hawking-Page Transition
Evan Coleman, Edward A. Mazenc, Vasudev Shyam +4
We obtain microstates accounting for the Gibbons-Hawking entropy in , along with a subleading logarithmic correction, from the solvable deformation of a seed CF…
Islands with Gravitating Baths: Towards ER = EPR
Louise Anderson, Onkar Parrikar, Ronak M Soni
We study the Page curve and the island rule for black holes evaporating into gravitating baths, with an eye towards establishing a connection with the ER=EPR proposal. We consider…
Seeing the Entanglement Wedge
Adam Levine, Arvin Shahbazi-Moghaddam, Ronak M Soni
We study the problem of revealing the entanglement wedge using simple operations. We ask what operation a semiclassical observer can do to bring the entanglement wedge into causal…
A Deformation for Curved Spacetimes from 3d Gravity
Edward A. Mazenc, Vasudev Shyam, Ronak M Soni
We propose a generalisation of the deformation to curved spaces by defining, and solving, a suitable flow equation for the partition function. We provide evidence it is…
A Path Integral Realization of Joint , and Flows
Jeremías Aguilera-Damia, Victor I. Giraldo-Rivera, Edward A. Mazenc +2
We recast the joint , and deformations as coupling the original theory to a mixture of topological gravity and gauge theory. This geometrizes the ge…
-Deformed Actions and (1,1) Supersymmetry
Evan A. Coleman, Jeremias Aguilera-Damia, Daniel Z. Freedman +1
We describe an algorithmic method to calculate the deformed Lagrangian of a given seed theory by solving an algebraic system of equations. This method is derived from th…
Entanglement Entropy, Relative Entropy and Duality
Upamanyu Moitra, Ronak M Soni, Sandip P. Trivedi
A definition for the entanglement entropy in both Abelian and non-Abelian gauge theories has been given in the literature, based on an extended Hilbert space construction. The resu…
Scalar Asymptotic Charges and Dual Large Gauge Transformations
Miguel Campiglia, Laurent Freidel, Florian Hopfmüller +1
In recent years soft factorization theorems in scattering amplitudes have been reinterpreted as conservation laws of asymptotic charges. In gauge, gravity, and higher spin theories…
On the Dynamics of Near-Extremal Black Holes
Pranjal Nayak, Ashish Shukla, Ronak M Soni +2
We analyse the dynamics of near-extremal Reissner-Nordström black holes in asymptotically four-dimensional Anti-de Sitter space (AdS). We work in the spherically symmetric appr…
A Note on S-Matrix Bootstrap for Amplitudes with Linear Spectrum
Pranjal Nayak, Rohan R. Poojary, Ronak M Soni
We work out constraints imposed by channel duality and analyticity on tree-level amplitudes of four identical real scalars, with the assumptions of a linear spectrum of exchanged p…
Entanglement Entropy in (3+1)-d Free Gauge Theory
Ronak M Soni, Sandip P. Trivedi
We consider the entanglement entropy for a free theory in dimensions in the extended Hilbert space definition. By taking the continuum limit carefully we obtain a re…
Aspects of Entanglement Entropy for Gauge Theories
Ronak M Soni, Sandip P. Trivedi
A definition for the entanglement entropy in a gauge theory was given recently in arXiv:1501.02593. Working on a spatial lattice, it involves embedding the physical state in an ext…
On The Entanglement Entropy For Gauge Theories
Sudip Ghosh, Ronak M. Soni, Sandip P. Trivedi
We propose a definition for the entanglement entropy of a gauge theory on a spatial lattice. Our definition applies to any subset of links in the lattice, and is valid for both Abe…
