Renormalization of entanglement entropy from topological terms
(American Physical Society, 2018-05)
We propose a renormalization scheme for entanglement entropy of three-dimensional CFTs with a four-dimensional asymptotically AdS gravity dual in the context of the gauge/gravity correspondence. The procedure consists in ...
Modular Hamiltonian for holographic excited states
(American Physical Society, 2020-07)
In this work we study the Tomita-Takesaki construction for a family of excited states that, in a strongly coupled CFT—at large N—correspond to coherent states in an asymptotically AdS spacetime geometry. We compute the ...
A note on the N = 2 super- W3 holographic dictionary
(Springer Science and Business Media Deutschland GmbH, 2020-12)
This is a long-overdue companion paper to [1]. We study the relation between sl(3|2) Chern-Simons supergravity on AdS3 and two-dimensional CFT’s with N = 2 super-W3 symmetry. Specifically, we carry out a complete analysis ...
Pulsating strings in Lunin-Maldacena backgrounds
(SPRINGER, 2011)
We consider pulsating strings in Lunin-Maldacena backgrounds, specifically in deformed Minkowski spacetime and deformed AdS(5) x S(5). We find the relation between the energy and the oscillation number of the pulsating ...
Open strings on D-branes from ABJM
(2015-06-08)
Abstract: We study open strings on giant gravitons (D-branes on cycles) in the ABJM/AdS<inf>4</inf> × ℂℙ<sup>3</sup> correspondence. We find that their energy spectrum has the same form as the one for closed strings, with ...
Violating the string winding number maximally in anti-de Sitter space
(American Physical Society, 2011-07)
We study n-string scattering amplitudes in three-dimensional anti-de Sitter space (AdS3). We focus our attention on the processes in which the winding number conservation is violated maximally, that is, those processes in ...
Finite dimensional vertex
(Springer, 2011-12-01)
The spectrum of linearized excitations of the Type IIB SUGRA on AdS(5) x S-5 contains both unitary and non-unitary representations. Among the non-unitary, some are finite-dimensional. We explicitly construct the pure spinor ...
