/cft Correspondence
Given a local quantum field theory net A on the de Sitter spacetime dS, where geodesic observers are thermalized at Gibbons-Hawking temperature, we look for observers that feel to be in a ground state, i.e. particle evolutions with positive generator, providing a sort of converse to the HawkingUnruh effect. Such positive energy evolutions always exist as noncommutative flows, but have only a pa...
متن کاملThe Kerr/CFT Correspondence
Quantum gravity in the region very near the horizon of an extreme Kerr black hole (whose angular momentum and mass are related by J = GM2) is considered. It is shown that consistent boundary conditions exist, for which the asymptotic symmetry generators form one copy of the Virasoro algebra with central charge cL = 12J ~ . This implies that the near-horizon quantum states can be identified with...
متن کاملAbout dS / CFT Correspondence
In this paper we will study some aspects of dS/CFT correspondence. We will focus on the relation between Witten's non-standard de Sitter inner product and correlators in the holographic dual conformal field theory. We will argue that from the definition of Witten's inner product and conjecture that the Hilbert space of initial states of massive scalar field on I − in de Sitter space corresponds...
متن کامل/ CFT correspondence on torus
The AdS/CFT correspondence is established for the case of AdS 3 space compactified on a filled rectangular torus with the CFT field on the boundary.
متن کاملThe 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 S ((D-1)-sphere), in which bulk de Sitter correlators with points on the boundary are related to CFT correlators on the sphere, and points on I+ (the future boundary of dSD) are mapped to the antipodal points on S relative to those on I−. For the case of dS3, w...
