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…

Comparative Study of Indicators of Chaos in the Closed and Open Dicke Model

Prasad Pawar, Arpan Bhattacharyya, B. Prasanna Venkatesh

The Dicke model, renowned for its superradiant quantum phase transition, also exhibits a transition from regular to chaotic dynamics. In this work, we provide a systematic, compara…

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…

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…
