We discuss analytic continuation from d-dimensional Lorentzian de Sitter (dSd) to d-dimensional Lorentzian anti-de Sitter (AdSd) space–time. We show that AdSd, with opposite signature of the metric, can be obtained as analytic continuation of a portion of dSd. This implies that the dynamics of (positive square-mass) scalar particles in AdSd can be obtained from the dynamics of tachyons in dSd. We discuss this correspondence both at the level of the solution of the field equations and of the…

Massive gravitino propagator in maximally symmetric spaces and fermions in dS/CFT

We extend the method of calculation of propagators in maximally symmetric spaces (Minkowski, dS, AdS and their euclidean versions) in terms of intrinsic geometric objects to the case of massive spin

Dark energy from holographic theories with hyperscaling violation

A bstractWe show that analytical continuation maps scalar solitonic solutions of Einstein-scalar gravity, interpolating between an hyperscaling violating and an Anti de Sitter (AdS) region, in flat

De Sitter scattering amplitudes in the Born approximation

We present a covariant framework to compute scattering amplitudes and potentials in a de Sitter background. In this setting, we compute the potential of a graviton-mediated scattering process

Two-dimensional dS/CFT correspondence

We investigate de Sitter/conformal field theory (dS/CFT) correspondence in two dimensions. We define the conserved mass of de Sitter spacetime and formulate the correspondence along the lines of the

Conformal vacua and entropy in de Sitter space

The de Sitter/conformal field theory (dS/CFT) correspondence is illuminated through an analysis of massive scalar field theory in d-dimensional de Sitter space. We consider a one-parameter family of

Vacuum states and the S matrix in dS / CFT

We propose a definition of dS/CFT correlation functions by equating them to S-matrix elements for scattering particles from I^- to I^+. In planar coordinates, which cover half of de Sitter space, we

The dS/CFT correspondence

A holographic duality is proposed relating quantum gravity on dSD (D-dimensional de Sitter space) to conformal field theory on a single SD−1 ((D-1)-sphere), in which bulk de Sitter correlators with

Mass, entropy and holography in asymptotically de Sitter spaces

We propose a novel prescription for computing the boundary stress tensor and charges of asymptotically de Sitter (dS) spacetimes from data at early or late time infinity. If there is a holographic

We investigate a recent proposal for defining a conserved mass in asymptotically de Sitter spacetimes that is based on a conjectured holographic duality between such spacetimes and Euclidean
