Large-N Collective Fields and de Sitter / CFT correspondence
Speaker(s): Sumit Das
Abstract: We derive the collective theory of singlet fields of large-N Sp(N) spin models and display its unconventional features. Using the known relationship between O(N) collective fields and higher spin fields of Vasiliev theory in AdS space, we argue that the unique features of the Sp(N) collective theory suggest an interpretation in terms of a higher spin theory in de Sitter space, as proposed by Anninos, Hartman and Strominger.  This is reminiscent of the way the Liouville mode is naturally  interpreted as time in supercritical worldsheet string theory.
