AdS plane waves and entanglement entropy
K. Narayan, Tadashi Takayanagi, Sandip P. Trivedi
AdS plane waves describe simple backgrounds which are dual to anisotropically excited systems with energy fluxes. Upon dimensional reduction, they reduce to hyperscaling violating…
AdS null deformations with inhomogeneities
K. Narayan
We study null deformations arising as near horizon limits of D3-brane analogs of inhomogenous plane waves. Restricting to normalizable deformations for the ca…
Cosmological singularities, AdS/CFT and de Sitter deformations
K. Narayan
We review aspects of certain time-dependent deformations of containing cosmological singularities and their gauge theory duals. Towards understanding these solutions bett…
On Lifshitz scaling and hyperscaling violation in string theory
K. Narayan
We explore string/M-theory constructions of holographic theories with Lifshitz scaling exponent and hyperscaling violation exponent , finding a range of -values. Some o…
