Mutual Information of Generalized Free Fields
Valentin Benedetti, Horacio Casini, Pedro J. Martinez
We study generalized free fields (GFF) from the point of view of information measures. We first review conformal GFF, their holographic representation, and the ambiguities in the a…
Pacman geometries and the Hayward term in JT gravity
Raúl Arias, Marcelo Botta-Cantcheff, Pedro J. Martinez
We study the Hayward term describing corners in the boundary of the geometry in the context of the Jackiw-Teitelboim gravity. These corners naturally arise in the computation of Ha…
Thermalization of Holographic Excited States
Pedro J. Martinez, Guillermo A. Silva
We propose a real time holographic framework to study thermalization processes of a family of QFT excited states. The construction builds on Skenderis-van Rees's holographic duals…
Entropic order parameters in weakly coupled gauge theories
Horacio Casini, Javier M. Magan, Pedro J. Martinez
The entropic order parameters measure in a universal geometric way the statistics of non-local operators responsible for generalized symmetries. In this article, we compute entropi…
Rényi entropies and area operator from gravity with Hayward term
Marcelo Botta-Cantcheff, Pedro J. Martinez, Juan F. Zarate
In the context of the holographic duality, the entanglement entropy of ordinary QFT in a subregion in the boundary is given by a quarter of the area of an minimal surface embedded…
Modular Hamiltonian for (holographic) excited states
Raúl Arias, Marcelo Botta-Cantcheff, Pedro J. Martinez +1
In this work we study the Tomita-Takesaki construction for a family of excited states that, in a strongly coupled CFT - at large -, correspond to coherent states in an asymptoti…
Holographic excited states in AdS Black Holes
Marcelo Botta-Cantcheff, Pedro J. Martínez, Guillermo A. Silva
We have recently presented a geometry dual to a Schwinger-Keldysh closed time contour, with two equal length Euclidean sections, which can be thought of as dual to the Thermo…
The Gravity Dual of Real-Time CFT at Finite Temperature
Marcelo Botta-Cantcheff, Pedro J. Martínez, Guillermo A. Silva
We present a spherically symmetric aAdS gravity solution with Schwinger-Keldysh boundary condition dual to a CFT at finite temperature defined on a complex time contour. The geomet…
Interacting fields in real-time AdS/CFT
Marcelo Botta-Cantcheff, Pedro J. Martínez, Guillermo A. Silva
We compute time-ordered 2- and 3-pt correlation functions of CFT scalar operators between generic in/out states. The calculation is holographically carried out by considering a non…
On excited states in real-time AdS/CFT
Marcelo Botta-Cantcheff, Pedro J. Martínez, Guillermo A. Silva
The Skenderis-van Rees prescription, which allows the calculation of time-ordered correlation functions of local operators in CFT's using holographic methods is studied and applied…
