Owen Pavel Fernandez Piedra, Jeferson de Oliveira
TL;DR
This paper investigates how quantum vacuum polarization affects the quasinormal modes of charged black holes, showing that quantum effects modify oscillation frequencies and improve the black hole's oscillatory behavior compared to classical models.
Contribution
It provides the first detailed analysis of vacuum polarization effects on quasinormal modes in semiclassical charged black holes.
Findings
Quantum vacuum polarization shifts quasinormal mode frequencies.
Semiclassical black holes exhibit more stable oscillations.
Quantum effects enhance the oscillatory nature of black holes.
Abstract
We report the results concerning the influence of vacuum polarization due to quantum massive vector, scalar and spinor fields on the scalar sector of quasinormal modes in spherically symmetric charged black holes. The vacuum polarization from quantized fields produces a shift in the values of the quasinormal frequencies, and correspondingly the semiclassical system becomes a better oscillator with respect to the classical Reissner-Nordstr\"om black hole.
