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…
Complex Saddles of Charged-AdS Gravitational partition function
Manishankar Ailiga, Shubhashis Mallik, Gaurav Narain
In this paper, we consider the Euclidean partition function of uncharged and charged black hole geometries in canonical and grand canonical ensemble for . It is…
Boundary choices and one-loop complex gravitational path integral
Manishankar Ailiga, Shubhashis Mallik, Gaurav Narain
The path integral of 4D Einstein-Hilbert gravity for the de Sitter-like Universe with fluctuations is investigated, and the transition amplitude from one boundary configuration to…
Lorentzian Robin Universe of Gauss-Bonnet Gravity
Manishankar Ailiga, Shubhashis Mallik, Gaurav Narain
The gravitational path-integral of Gauss-Bonnet gravity is investigated and the transition from one spacelike boundary configuration to another is analyzed. Of particular interest…
