Nonequilibrium dynamics of the O(N) model on dS_3 and AdS crunches
S. Prem Kumar, Vladislav Vaganov
We study the nonperturbative quantum evolution of the interacting O(N) vector model at large-N, formulated on a spatial two-sphere, with time dependent couplings which diverge at f…
Quasinormal modes and holographic correlators in a crunching AdS geometry
S. Prem Kumar, Vladislav Vaganov
We calculate frequency space holographic correlators in an asymptotically AdS crunching background, dual to a relevant deformation of the M2-brane CFT placed in de Sitter spacetime…
Holographic entanglement entropy for massive flavours in dS_4
Vladislav Vaganov
We examine the holographic entanglement entropy of spherical regions in de Sitter space in the presence of massive flavour fields which are modelled by probe D7 branes in AdS_5xS^5…
Probing crunching AdS cosmologies
S. Prem Kumar, Vladislav Vaganov
Holographic gravity duals of deformations of CFTs formulated on de Sitter spacetime contain FRW geometries behind a horizon, with cosmological big crunch singularities. Using a spe…
