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 th... read more

Probe Branes, time dependent couplings and thermallization in AdS/CFT
Speaker(s): Sumit Das
Abstract: We study time dependent couplings in conformal field theories using rotating probe branes in AdS X S spacetimes. We find that induced metrics on the brane worldvolumes develop horizons with characteristic Hawking temperatures even when there is no black hole in the bulk. This framework is used to ob... read more

Gauge Duals of some Singularities
Speaker(s): Sumit Das
Abstract: Certain classes of cosmological backgrounds in asymptotically anti-de-Sitter space-times have hologropically dual descriptions in terms of gauge theories. We analyse such backgrounds with smooth initial conditions, where curvatures become strong in a finite time and the gravity equations break down.... read more
