Quantum Love and ringdown near extremality
Arindam Bhattacharjee, Muktajyoti Saha, M. V. S. Saketh
In this paper we discuss the quasinormal modes and the tidal responses of a four-dimensional asymptotically flat Reissner-Nördstrom black hole near extremality and investigate the…
Quantum Love Numbers are Non-Zero
Asaad Elkhidir, Godwin Martin, Julio Parra-Martinez +1
The static Love numbers of four-dimensional Schwarzschild black holes vanish classically. We show that this is not true in the quantum theory. Working in the worldline effective fi…
Dynamical tidal Love numbers of black holes under generic perturbations: Connecting black hole perturbation theory with effective field theory
Sumanta Chakraborty, M. V. S Saketh, Tanja Hinderer +1
The foundation for modeling the coupling of the internal structure of compact objects in binary systems to their dynamics and emitted gravitational waves is a systematic effective…
Strong-field Gravitational Wave Lensing in the Kerr Background
M. V. S. Saketh, Rajes Ghosh, Anuj Mishra
Gravitational-wave (GW) lensing can encode valuable information about the properties of the intervening lens, but most existing studies remain restricted to the small-deflection, w…
Kerr-Newman quasinormal modes and Seiberg-Witten theory
Hector O. Silva, Jung-Wook Kim, M. V. S. Saketh
It was recently suggested the quasinormal-mode spectrum of black holes is related to a class of four-dimensional super Yang-Mills theories described by Seiberg-Witt…
Investigating tidal heating in neutron stars via gravitational Raman scattering
M. V. S. Saketh, Zihan Zhou, Suprovo Ghosh +2
We present a scattering amplitude formalism to study the tidal heating effects of nonspinning neutron stars incorporating both worldline effective field theory and relativistic ste…
Dynamical Tidal Response of Kerr Black Holes from Scattering Amplitudes
M. V. S. Saketh, Zihan Zhou, Mikhail M. Ivanov
We match scattering amplitudes in point particle effective field theory (EFT) and general relativity to extract low frequency dynamical tidal responses of rotating (Kerr) black hol…
Modeling horizon absorption in spinning binary black holes using effective worldline theory
M. V. S. Saketh, Jan Steinhoff, Justin Vines +1
The mass and spin of black holes (BHs) in binary systems may change due to the infall of gravitational-wave (GW) energy down the horizons. For spinning BHs, this effect enters at 2…
Scattering of gravitational waves off spinning compact objects with an effective worldline theory
M. V. S. Saketh, Justin Vines
We study the process, within classical general relativity, in which an incident gravitational plane wave, of weak amplitude and long wavelength, scatters off a massive spinning com…
Conservative and radiative dynamics in classical relativistic scattering and bound systems
M. V. S. Saketh, Justin Vines, Jan Steinhoff +1
As recent work continues to demonstrate, the study of relativistic scattering processes leads to valuable insights and computational tools applicable to the relativistic bound-orbi…
Probing the large scale structure using gravitational-wave observations of binary black holes
Aditya Vijaykumar, M. V. S. Saketh, Sumit Kumar +2
Third generation gravitational-wave (GW) detectors are expected to detect a large number of binary black holes (BBHs) to large redshifts, opening up an independent probe of the lar…
Torsion driven Inflationary Magnetogenesis
M. V. S. Saketh, R. Kothari, P. Jain
We show that breaking of the conformal invariance of electromagnetic Lagrangian which is required for inflationary magnetogenesis arises naturally in the Poincar{é} Gauge Theory. W…
