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...

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...

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...

Magneto-optical Kerr effect in surface engineered 2D hexagonal boron nitride
Magnetism in atomically thin functional materials can be an important phenomenon for exploring two-dimensional magneto-optics. Magneto-optical...

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...

Topological Kerr effects in two-dimensional magnets with broken inversion symmetry
The whorls of localized moments in chiral magnetic structures, such as skyrmions, lead to a quantized topological charge, which may make them useful...

Theory of optical axion electrodynamics and application to the Kerr effect in topological antiferromagnets
Emergent axion electrodynamics in magneto-electric media is expected to provide novel ways to detect and control material properties with...

The Kerr–Bumblebee exact massive and massless scalar quasibound states and Hawking radiation
In this letter, we will focus on the Klein–Gordon equation with rotating axially symmetric black hole solution of the Einstein–Bumblebee theory, so...

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...

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...

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...

Three-state nematicity and magneto-optical Kerr effect in the charge density waves in kagome superconductors
The kagome lattice provides a fascinating playground to study geometrical frustration, topology and strong correlations. The newly discovered kagome...

A Rutherford-like formula for scattering off Kerr-Newman BHs and subleading corrections
By exploiting the Kerr-Schild gauge, we study the scattering of a massive (charged) scalar off a Kerr-Newman black hole. In this gauge, the...

Conserved charges of the Kerr black hole revisited
We revisit the Kerr black hole as cast in the Boyer–Lindquist, Kerr–Schild and Weyl canonical coordinates, and calculate its total mass/energy and...

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...

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...

The extremal Kerr entropy in higher-derivative gravities
We investigate higher derivative corrections to the extremal Kerr black hole in the context of heterotic string theory with α ′ corrections and of a...

Theoretical studies of magneto-optical Kerr and Faraday effects in two-dimensional second-order topological insulators
Optical approaches are useful for studying the electronic and spin structure of materials. Here, based on the tight-binding model and linear response...
