Black hole Near Horizons through the Looking Glass
Arjun Bagchi, Arkachur Bhattacharya, Sharang Rajesh Iyer +1
We show that the near horizon of a generic non-extremal black hole (BH) can be understood in terms of a Carrollian geometry with two null directions, also called a String-Carroll (…
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…
Localized tachyons in C^3/Z_N
David R. Morrison, K. Narayan, M. Ronen Plesser
We study the condensation of localized closed string tachyons in C^3/Z_N nonsupersymmetric noncompact orbifold singularities via renormalization group flows that preserve supersymm…
Notes on hyperscaling violating Lifshitz and shear diffusion
Kedar S. Kolekar, Debangshu Mukherjee, K. Narayan
We explore in greater detail our investigations of shear diffusion in hyperscaling violating Lifshitz theories in arXiv:1604.05092 [hep-th]. This adapts and generalizes the membran…
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…
On the third law of black hole dynamics
Naresh Dadhich, K. Narayan
The third law of black hole dynamics states that the surface gravity (temperature) of black hole cannot be reduced to zero in finite sequence of physical interactions. We argue tha…
