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…
CMB from CFT
Ishan Mata, Suvrat Raju, Sandip Trivedi
During inflation, spacetime is approximately described by de Sitter space which is conformally invariant with the symmetry group SO(1,4). This symmetry can significantly constrain…
Entangled Dilaton Dyons
Nilay Kundu, Prithvi Narayan, Nilanjan Sircar +1
Einstein-Maxwell theory coupled to a dilaton is known to give rise to extremal solutions with hyperscaling violation. We study the behaviour of these solutions in the presence of a…
Supersymmetric Chern-Simons Theories with Vector Matter
Sachin Jain, Sandip P. Trivedi, Spenta R. Wadia +1
In this paper we discuss SU(N) Chern-Simons theories at level k with both fermionic and bosonic vector matter. In particular we present an exact calculation of the free energy of t…
Bianchi Attractors: A Classification of Extremal Black Brane Geometries
Norihiro Iizuka, Shamit Kachru, Nilay Kundu +3
Extremal black branes are of interest because they correspond to the ground states of field theories at finite charge density in gauge/gravity duality. The geometry of such a brane…
