Singletons and Logarithmic Cft in Ads/cft Correspondence
We discuss a possible relation between singletons in AdS space and logarithmic conformal field theories at the boundary of AdS. It is shown that the bulk Lagrangian for singleton field (singleton dipole) induces on the boundary the two-point correlation function for logarithmic pair. Bulk interpretation of mixing between logarithmic operator D and zero mode operator C under the scale transforma...

We discuss the origin of logarithmic operators in AdS 3 string theory. It is shown that j = − 1 2 representation can give logarithmic correlation functions in the boundary CFT. Singletons play a special role in AdS 3 /CF T 2 correspondence as they also give logarithmic correlation functions in boundary CFT. For this one has to cross the j = − 1 2 barrier and define correlation functions for j >...
متن کاملOn the AdS/CFT Correspondence and Logarithmic Operators
Logarithmic conformal field theory is investigated using the ADS/CFT correspondence and a novel method based on nilpotent weights. Using this device we add ghost fermions and point to a BRST invariance of the theory. PACS : 11.25.Hf

* In my opinion the connection of fractional-level and supergroup Wess-ZuminoWitten models to string theory is remote. It is definitely not substantiated in any of the given references. Unless this connection can be described more concretely (a precise reference to a paper in which this is discussed would be enough), these models should rather be counted among those “studied for their own sake”.
متن کامل/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...
