Notes on time entanglement and pseudo-entropy
K. Narayan, Hitesh K. Saini
Following arXiv:2210.12963 [hep-th], we investigate aspects of the time evolution operator regarded as a density operator and associated entanglement-like structures in various qua…
de Sitter space, extremal surfaces and "time-entanglement"
K. Narayan
We refine previous investigations on de Sitter space and extremal surfaces anchored at the future boundary . Since such surfaces do not return, they require extra data or boun…
Small Schwarzschild de Sitter black holes, quantum extremal surfaces and islands
Kaberi Goswami, K. Narayan
We study 4-dimensional Schwarzschild de Sitter black holes in the regime where the black hole mass is small compared with the de Sitter scale. Then the de Sitter temperature is ver…
M5-brane prongs, string soliton bound states and wall-crossing
Varun Gupta, K. Narayan
We study abelian M5-brane field configurations representing BPS bound states of self-dual string solitons whose locations correspond to the endlines of M2-branes ending on the M5-b…
Cosmologies, singularities and quantum extremal surfaces
Kaberi Goswami, K. Narayan, Hitesh K. Saini
Following arXiv:2012.07351 [hep-th], we study quantum extremal surfaces in various families of cosmologies with Big-Crunch singularities, by extremizing the generalized entropy in…
Cosmological singularities, entanglement and quantum extremal surfaces
A. Manu, K. Narayan, Partha Paul
We study aspects of entanglement and extremal surfaces in various families of spacetimes exhibiting cosmological, Big-Crunch, singularities, in particular isotropic Kasner. T…
