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.…
