Supersymmetric boundary algebras in AdS gravity: constraints, Dirac brackets and non-locality
Nabamita Banerjee, Vedant Bhutra, Suvankar Dutta +1
We study supersymmetric boundary dynamics in AdS gravity by treating boundary conditions as constrained reductions of a generic Chern-Simons boundary phase space. We focus on h…
Logarithmic corrections to the entropy of near-extremal rotating black holes
Nabamita Banerjee, Koustubh Guha, Muktajyoti Saha
An interesting feature of quantum corrections to the Bekenstein--Hawking entropy is the appearance of logarithmic area terms, whose coefficients are governed by the spectrum of mas…
Supersymmetric extensions of Kac-Moody boundary conditions in AdS gravity
Nabamita Banerjee, Vedant Bhutra, Suvankar Dutta +1
We extend the Kac-Moody (KM) boundary conditions of AdS gravity by incorporating fermionic fields. For AdS supergravity, we show that there are two poss…
Massless limit of massive self-interacting vector fields
Nabamita Banerjee, Jitesh Singh
We study massive self-interacting vector field theories with mass added ``by hand". We show that the massless limit of the quartic self-interacting vector field theory is not smoot…
Mock Modularity Of Twisted Index In CHL Models
Nabamita Banerjee, Vedant Bhutra, Ranveer Kumar Singh
We study the twisted partition function of quarter BPS states in CHL models and show that for a large class of single-centered black holes, the degeneracy of microstates is given b…
AdS S-Matrix for Massive Vector Fields
Nabamita Banerjee, Amogh Neelkanth Desai, Karan Fernandes +2
We generalize a recent ``AdS S-matrix" formulation for interacting massive scalars on AdS spacetimes to the case of massive vector fields. This method relies on taking the infinite…
