Quasinormal modes are eigenmodes of dissipative systems. Perturbations of classical
gravitational backgrounds involving black holes or branes naturally lead to quasinormal …

It has been 30 years since the discovery of the Unruh effect. It has played a crucial role in
our understanding that the particle content of a field theory is observer dependent. This …

Recently, Bueno, Cano, and Hennigar [Regular black holes from pure gravity, arXiv:
2403.04827.] proposed a generic approach for incorporating an infinite tower of higher …

We make a thorough investigation of the asymptotic quasinormal modes of the four-and five-
dimensional Schwarzschild black holes for scalar, electromagnetic, and gravitational …

We study quasinormal modes (QNMs) in a five-dimensional electrically charged Bardeen
black hole spacetime by considering the scalar and electromagnetic field perturbations. The …

We compute the absorption cross section and the total power carried by gravitons in the
evaporation process of a higher-dimensional non-rotating black hole. These results are …

We calculate the exact values of the quasinormal frequencies for an electromagnetic field
and a gravitational perturbation moving in D-dimensional de Sitter spacetime (D≥ 4). We …

A bstract We present a detailed discussion of the entanglement structure of vector fields
through canonical quantization. We quantize Maxwell theory in Rindler space in Lorenz …

Charged particle emission from black holes with sufficiently large charge is exponentially
suppressed. As a result, such black holes are driven towards extremality by the emission of …

We analyze the scattering of a planar monochromatic electromagnetic wave incident upon a
Schwarzschild black hole. We obtain accurate numerical results from the partial wave …
