Classical Black Hole Scattering to Celestial Amplitudes in Effective Theories of Gravity
Saptaswa Ghosh
This thesis investigates quantum field theoretic approaches to classical gravity beyond General Relativity. Using worldline effective field theory, worldline quantum field theory,…
Observables from classical black hole scattering in Scalar-Tensor theory of gravity from worldline quantum field theory
Arpan Bhattacharyya, Debodirna Ghosh, Saptaswa Ghosh +1
In this article, we compute the two observables, impulse and waveform, in a black hole scattering event for the Scalar-Tensor theory of gravity with a generic scalar potential usin…
Heterotic Footprints in Classical Gravity: PM dynamics from On-Shell soft amplitudes at one loop
Arpan Bhattacharyya, Saptaswa Ghosh, Ankit Mishra +1
We study classical scattering of charged black holes in Einstein-Maxwell-Dilaton (EMD) theory. Working in the classical (Post-Minkowskian) regime, we extract the conservative two-b…
Finite cutoff JT gravity: Baby universes, Matrix dual, and (Krylov) Complexity
Arpan Bhattacharyya, Saptaswa Ghosh, Sounak Pal +1
In this paper, as an application of the `Complexity = Volume' proposal, we calculate the growth of the interior of a black hole at late times for finite cutoff JT gravity. Due to t…
Worldline effective field theory of inspiralling black hole binaries in presence of dark photon and axionic dark matter
Arpan Bhattacharyya, Saptaswa Ghosh, Sounak Pal
We investigate the correction to the potential that gives rise to the bound orbits and radiation from non-spinning inspiralling binary black holes in a dark matter environment cons…
On the resolution of categorical symmetries in (Non-) Unitary Rational CFTs
Arpan Bhattacharyya, Saptaswa Ghosh, Sounak Pal +1
We explore several aspects of the categorical symmetry-resolved entanglement entropy (SREE) in two-dimensional Rational Conformal Field Theories (RCFTs) and express it directly in…
