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…

MHV Graviton Scattering Amplitudes and Current Algebra on the Celestial Sphere
Shamik Banerjee, Sudip Ghosh, Partha Paul
The Cachazo-Strominger subleading soft graviton theorem for a positive helicity soft graviton is equivalent to the Ward identities for currents. This n…

Cosmological singularities and 2-dimensional dilaton gravity
Ritabrata Bhattacharya, K. Narayan, Partha Paul
We study Big-Bang or -Crunch cosmological singularities in 2-dimensional dilaton-gravity-scalar theories, in general obtained by dimensional reduction of higher dimensional theorie…
