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…
Resolving Degeneracies in Complex and -KSW
Manishankar Ailiga, Shubhashis Mallik, Gaurav Narain
Lorentzian gravitational path integral for the Gauss-Bonnet gravity in is studied in the mini-superspace ansatz for metric. The gauge-fixed path-integral for Robin boundary ch…
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…
