IR behaviour of one-loop complex $R \times S^{3}$ saddles

Shubhashis Mallik, Gaurav Narain

Gravitational path-integral over $R \times S^{3}$ complex metrics with fluctuations is studied in 4D for Einstein-Hilbert gravity in Lorentzian signature, with the aim to inv…

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 $A d S_{d + 1}$ black hole geometries in canonical and grand canonical ensemble for $d \geq 3$ . It is…

Resolving Degeneracies in Complex $R \times S^{3}$ and $θ$ -KSW

Manishankar Ailiga, Shubhashis Mallik, Gaurav Narain

Lorentzian gravitational path integral for the Gauss-Bonnet gravity in $4 D$ 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…
