From the Old to the New Starobinsky Inflation
Shinji Hirano
Starobinsky's original model of inflation, driven by the trace anomaly of conformal fields, and its (scalaron) formulation are often treated separately. The original anomal…
A Third-Quantized Description of Spacetime Wormholes in AdS/CFT
Shinji Hirano
We propose an extension of AdS/CFT in which quantum gravitational wavefunctions of connected bulk geometries are assembled into a Fock space of universes. Splitting and joining int…
Wavefunctions of AdS Universes and -deformed Torus Partition Functions
Shinji Hirano
We study wavefunctions of quantum gravity in asymptotically AdS spacetimes and their relation to -deformed torus partition functions. We show that the deformed partit…
The holography of duality in Super-Yang-Mills theory
Oren Bergman, Shinji Hirano
The space of supersymmetric Yang-Mills theories exhibits an intricate structure of global one-form symmetries and duality orbits. In this paper we s…
Replica Wormholes from Liouville Theory
Shinji Hirano, Tsunehide Kuroki
The replica wormholes are a key to the existence of the islands that play a central role in a recent proposal for the resolution of the black hole information paradox. In this pape…
Deformation of Stress-Tensor Correlators from Random Geometry
Shinji Hirano, Tatsuki Nakajima, Masaki Shigemori
We study stress-tensor correlators in the -deformed conformal field theories in two dimensions. Using the random geometry approach to the deformation, we devel…
