Boundary conditions for axionic wormholes, imaginary distance bound and KSW allowability
Shubhashis Mallik, Neha, Gaurav Narain
We study four-dimensional axion wormholes in the Lorentzian mini-superspace path integral using dual scalar and three-form flux formulations. We analyze this duality for generic me…

IR behaviour of one-loop complex saddles
Shubhashis Mallik, Gaurav Narain
Gravitational path-integral over complex metrics with fluctuations is studied in 4D for Einstein-Hilbert gravity in Lorentzian signature, with the aim to inv…

Note on KSW-allowability of Wine-Glass Geometry
Manishankar Ailiga, Gaurav Narain
In this note we consider no-boundary instantons and wine-glass geometries which are of interest in the context of quantum cosmology. While the former usually appears as a dominant…
