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…

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…
