Tidal heating as a discriminator for horizons in equatorial eccentric extreme mass ratio inspirals

S Datta, R Brito, SA Hughes, T Klinger, P Pani - Physical Review D, 2024 - APS
Tidal heating in a binary black hole system is driven by the absorption of energy and angular
momentum by the black hole's horizon. Previous works have shown that this phenomenon …

Dynamical Love numbers for area quantized black holes

S Nair, S Chakraborty, S Sarkar - Physical Review D, 2023 - APS
We study the tidal deformability of horizonless exotic compact objects, with implications for
area quantized black holes. Since, any such horizonless compact object, including an area …

Imprint of black hole area quantization and Hawking radiation on inspiraling binary

S Datta, KS Phukon - Physical Review D, 2021 - APS
We study the potential of gravitational wave astronomy to observe the quantum aspects of
black holes with tidal heating. According to Bekenstein's quantization, we find that black hole …

Landauer's principle and black hole area quantization

B Bagchi, A Ghosh, S Sen - General Relativity and Gravitation, 2024 - Springer
This article assesses Landauer's principle from information theory in the context of area
quantization of the Schwarzschild black hole. Within a quantum-mechanical perspective …

Signature of nonuniform area quantization on black hole echoes

K Chakravarti, R Ghosh, S Sarkar - Physical Review D, 2022 - APS
A classical black hole is characterized by a horizon that absorbs the radiation of all
frequencies incident on it. The perturbation of these black holes is well understood via …

Echoes of black holes in Einstein-nonlinear electrodynamic theories

A Sang, M Zhang, SW Wei, J Jiang - The European Physical Journal C, 2023 - Springer
Black hole echo is an important observable that can help us better understand gravitational
theories. The non-linear electrodynamic black holes can admit multi-horizon, and the …

Gravitational-wave echoes from numerical-relativity waveforms via spacetime construction near merging compact objects

S Ma, Q Wang, N Deppe, F Hébert, LE Kidder, J Moxon… - Physical Review D, 2022 - APS
We propose a new approach toward reconstructing the late-time near-horizon geometry of
merging binary black holes, and toward computing gravitational-wave echoes from exotic …

Formation and stability of area quantized black holes

K Chakravarti, R Ghosh, S Sarkar - Physical Review D, 2024 - APS
We investigate the ergoregion instability of area-quantized rotating quantum black holes
(QBH) under gravitational perturbation. We show that the instability can be avoided in binary …

Two distinct types of echoes in compact objects

SF Shen, K Lin, T Zhu, YP Yan, CG Shao, WL Qian - Physical Review D, 2024 - APS
In the black hole perturbation theory framework, two different physical pictures for echoes in
compact objects have been proposed. The first mechanism interprets echoes as repeated …

Echoes from Beyond: Detecting Gravitational Wave Quantum Imprints with LISA

N Deppe, L Heisenberg, H Inchauspé… - arXiv preprint arXiv …, 2024 - arxiv.org
We assess the prospects for detecting gravitational wave echoes arising due to the quantum
nature of black hole horizons with LISA. In a recent proposal, Bekenstein's black hole area …
