Krylov complexity and the growth of the black hole interior in 3D gravity
Arpan Bhattacharyya, Sounak Pal, Juan F. Pedraza
We investigate the growth of the black hole interior in three-dimensional gravity from the boundary theory. For the two-sided BTZ black hole, we propose a boundary reconstruction o…
Pure gravity OPE density for genus-two handlebody in
Saptaswa Ghosh, Sounak Pal
In this work, we compute the operator product expansion density for the genus-two handlebody by exploiting its duality with extremal conformal field theories arXiv:0710.2129. Using…
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…
