The (No) Boundary Proposal and excited states in de Sitter holography
Marcelo Botta-Cantcheff, Facundo Lorenzo Cruz, Pedro J. Martinez
In the AdS/CFT framework, vacuum and excited states are systematically described by imposing arbitrary Dirichlet boundary conditions at the AdS boundary. Furthermore, there are exp…
Real-time methods in JT/SYK holography
Raúl Arias, Marcelo Botta-Cantcheff, Pedro J. Martinez
We study the conventional holographic recipes and its real-time extensions in the context of the correspondence between SYK quantum mechanics and JT gravity. We first observe that…
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…
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…
