extremal surfaces, replicas, boundary Renyi entropies in and time entanglement
Kanhu Kishore Nanda, K. Narayan, Somnath Porey +1
We develop further previous work on de Sitter extremal surfaces and time entanglement structures in quantum mechanics. In the first part, we first discuss explicit quotient geometr…

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…
