dS/CFT at uniform energy density and a de Sitter "bluewall"
Diptarka Das, Sumit R. Das, K. Narayan
We describe a class of spacetimes that are asymptotically de Sitter in the Poincare slicing. Assuming that a dS/CFT correspondence exists, we argue that these are gravity duals to…
Quantum Quench and Double Trace Couplings
Pallab Basu, Diptarka Das, Sumit R. Das +1
We consider quantum quench by a time dependent double trace coupling in a strongly coupled large N field theory which has a gravity dual via the AdS/CFT correspondence. The bulk th…
Double Trace Flows and Holographic RG in dS/CFT correspondence
Diptarka Das, Sumit R. Das, Gautam Mandal
If there is a dS/CFT correspondence, time evolution in the bulk should translate to RG flows in the dual euclidean field theory. Consequently, although the dual field is expected t…
