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…
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,…
On the resolution of categorical symmetries in (Non-) Unitary Rational CFTs
Arpan Bhattacharyya, Saptaswa Ghosh, Sounak Pal +1
We explore several aspects of categorical symmetry-resolved entanglement entropy (SREE) directly within two-dimensional rational conformal field theory (RCFT) (without invoking any…
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…
Love beyond Einstein: Metric reconstruction and Love number in quadratic gravity using WEFT
Arpan Bhattacharyya, Saptaswa Ghosh, Naman Kumar +2
We study tidal Love numbers of static black holes in four-dimensional quadratic theory of gravity, extending the result of GR. We use worldline effective field theory (WEFT) method…
The Sky Remembers everything: Celestial amplitude, Shadow and OPE in quadratic EFT of gravity
Arpan Bhattacharyya, Saptaswa Ghosh, Sounak Pal
In this paper, we compute the celestial amplitude arising from higher curvature corrections to Einstein gravity, incorporating phase dressing. The inclusion of such corrections lea…
