Genuine Multi-Entropy in Abelian Chern--Simons Theory: Exact Key-Ring Collapse and Its Breakdown for Generic Link States
Yen-Cheng Chang, Kaberi Goswami, Norihiro Iizuka +1
We study genuine multi-entropy in Abelian Chern-Simons theory. For key-ring link states, where only the linking numbers between one distinguished component and the rem…
Attractor saddle for 5D black hole index
Soumya Adhikari, Pavan Dharanipragada, Kaberi Goswami +1
In a recent paper, Anupam, Chowdhury, and Sen [arXiv:2308.00038] constructed the non-extremal saddle that reproduces the supersymmetric index of the BMPV black hole with three inde…
No-boundary extremal surfaces in slow-roll inflation and other cosmologies
Kaberi Goswami, K. Narayan, Gopal Yadav
Building on previous work on de Sitter extremal surfaces anchored at the future boundary, we study no-boundary extremal surfaces in slow-roll inflation models, with perturbations t…
Small Schwarzschild de Sitter black holes, the future boundary and islands
Kaberi Goswami, K. Narayan
We continue the study of 4-dimensional Schwarzschild de Sitter black holes in the regime where the black hole mass is small compared with the de Sitter scale, following arXiv:2207.…
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…
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…
