Dynamical tidal response of regular black holes: Perturbative analysis and shell EFT interpretation
Arpan Bhattacharyya, Naman Kumar, Shailesh Kumar
We compute the frequency-dependent quadrupolar tidal response of Bardeen, Hayward, and Fan-Wang regular black holes in the polar and axial sectors by solving the coupled gravitatio…

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…
