A-type Sigma Models from Differential Poisson Geometry
Cesar Arias, Per Sundell
We study the differential Poisson sigma model (DPSM) in the symplectic case and show that its classical reduction defines a distinguished class of A-type models on symplectic targe…
Reconstructing the boundary of AdS from an infrared defect
Cesar Arias
We argue that the boundary of an asymptotically anti-de Sitter (AdS) space of dimension , say , can be locally reconstructed from a codimension-two defect located in…
Liouville description of conical defects in dS, Gibbons-Hawking entropy as modular entropy, and dS holography
Cesar Arias, Felipe Diaz, Rodrigo Olea +1
We model the back-reaction of a static observer in four-dimensional de Sitter spacetime by means of a singular quotient. The set of fixed points of the …
De Sitter Space and Entanglement
Cesar Arias, Felipe Diaz, Per Sundell
We argue that the notion of entanglement in de Sitter space arises naturally from the non-trivial Lorentzian geometry of the spacetime manifold, which consists of two disconnected…
Einstein-AdS action, renormalized volume/area and holographic Renyi entropies
Giorgos Anastasiou, Ignacio J. Araya, Cesar Arias +1
We exhibit the equivalence between the renormalized volume of asymptotically anti-de Sitter (AAdS) Einstein manifolds in four and six dimensions, and their renormalized Euclidean b…
Bosonic Higher Spin Gravity in any Dimension with Dynamical Two-Form
Cesar Arias, Roberto Bonezzi, Per Sundell
We first propose an alternative to Vasiliev's bosonic higher spin gravities in any dimension by factoring out a modified sp(2) gauge algebra. We evidence perturbative equivalence o…
