Universal Ladder Structure Across Scales: From Quantum to Black Hole Physics
Rajes Ghosh, Rajendra Prasad Bhatt, Sumanta Chakraborty +1
Second-order ordinary linear differential equations appear ubiquitously across physics, describing the behavior of systems from the quantum world of atoms to the classical world of…
Response of a Kerr black hole to a generic tidal perturbation
Rajendra Prasad Bhatt, Sumanta Chakraborty, Sukanta Bose
We derive the response, the real part of which provides the tidal Love numbers, for non-extremal as well as extremal Kerr black holes under generic tidal perturbations. Our results…
Scalar tidal response of a rotating BTZ black hole
Rajendra Prasad Bhatt, Chiranjeeb Singha
We study the response of a rotating BTZ black hole to the scalar tidal perturbation. We show that the real component of the tidal response function isn't zero, indicating that a ro…
Rotating black holes experience dynamical tides
Rajendra Prasad Bhatt, Sumanta Chakraborty, Sukanta Bose
We find the dynamical tidal response of a Kerr black hole (BH) and demonstrate its tidal Love numbers to be non-vanishing when present in a non-axisymmetric external tidal field. T…
