Scalar QNM spectra of Kerr and Reissner-Nordström revealed by eigenvalue repulsions in Kerr-Newman
Recent studies of the gravito-electromagnetic frequency spectra of Kerr-Newman (KN) black holes have revealed two families of quasinormal modes...

Analyticity of Quasinormal Modes in the Kerr and Kerr–de Sitter Spacetimes
We prove that quasinormal modes (or resonant states) for linear wave equations in the subextremal Kerr and Kerr–de Sitter spacetimes are real...

Unconventional photon blockade induced by the self-Kerr and cross-Kerr nonlinearities
We study the use of the self-Kerr and cross-Kerr nonlinearities to realize strong photon blockade in a weakly driven, four-mode optomechanical...

Strong Cosmic Censorship in Kerr-Newman-de Sitter
Christodoulou’s formulation of Strong Cosmic Censorship (SCC) holds true for Kerr-de Sitter black holes. On the other hand, Reissner-Nordström-de...

Gravitational radiations of Kerr black hole from warped symmetries
The warped conformal symmetries have been found in the covariant phase space of a set of non-trivial diffeomorphism near the Kerr black hole horizon....

Testing beyond-Kerr spacetimes with GWTC-3
The Kerr spacetime is a fundamental solution of general relativity (GR), describing the gravitational field around a rotating, uncharged black hole...

Warped conformal symmetries of the accelerating Kerr black hole
Recent studies on the holographic descriptions of Kerr black holes indicate that the conformal or the warped conformal symmetries are responsible for...

Compactifying the Kerr-Schild double copy
We show that the classical double copy relationship for Kerr-Schild spacetimes can be dimensionally reduced to give a natural notion of the double...

The ultrarelativistic limit of Kerr
The massless (or ultrarelativistic) limit of a Schwarzschild black hole with fixed energy was determined long ago in the form of the Aichelburg-Sexl...

Light propagation in Kerr spacetime
We explicitly solve the equations for the propagation of an electromagnetic wave up to the subleading order geometric optics expansion in the Kerr...

Sudden breakdown of effective field theory near cool Kerr-Newman black holes
It was recently shown that (near-)extremal Kerr black holes are sensitive probes of small higher-derivative corrections to general relativity. In...

Kerr Stability in External Regions
In 2003, Klainerman and Nicolò [
14 ] proved the stability of Minkowski in the case of the exterior of an outgoing null cone. Relying on the method...

Collisions of particles near Kerr-MOG black holes
We consider the collision of two particles having distinct rest masses and orbiting near a Kerr-MOG black hole, and we further determine the...

Thermodynamics of the near-extremal Kerr spacetime
We examine the thermodynamics of a near-extremal Kerr black hole, and demonstrate that the geometry behaves as an ordinary quantum system with a...

Kerr binary dynamics from minimal coupling and double copy
We construct a new Yang-Mills Lagrangian based on a notion of minimal coupling that incorporates classical spin effects. The construction relies on...

Kerr black hole shadows cast by extraordinary light rays with Weyl corrections
We investigate the equation of motion for photons with Weyl corrections in a Kerr black hole spacetime in a small coupling case. Our results show...

Massively scalable Kerr comb-driven silicon photonic link
The growth of computing needs for artificial intelligence and machine learning is critically challenging data communications in today’s data-centre...

Adiabatic theory in Kerr spacetimes
We outline the essential features of the adiabatic theory and demonstrate how test particle motion in general relativity may be investigated using...

Parametrically driven pure-Kerr temporal solitons in a chip-integrated microcavity
The discovery that externally driven nonlinear optical resonators can sustain ultrashort pulses (solitons) corresponding to coherent optical...

Quantum Kerr-de Sitter black holes in three dimensions
We use braneworld holography to construct a three-dimensional quantum-corrected Kerr-de Sitter black hole, exactly accounting for semi-classical...
