Emergent metric from wavelet-transformed quantum field theory
Å imon Vedl, Daniel J. George, Fil Simovic +5
We introduce a method of reverse holography by which a bulk metric is shown to arise from locally computable multiscale correlations of a boundary quantum field theory (QFT). The m…
Padé metrics for black hole perturbations and light rings
Swayamsiddha Maharana, Fil Simovic, Ioannis Soranidis +1
Most distinguishing features of black holes and their mimickers are concentrated near the horizon. In contrast, astrophysical observations and theoretical considerations primarily…
Horizon-bound objects: Kerr--Vaidya solutions
Pravin K. Dahal, Swayamsiddha Maharana, Fil Simovic +1
Kerr-Vaidya metrics are the simplest dynamical axially-symmetric solutions, all of which violate the null energy condition and thus are consistent with the formation of a trapped r…
Semi-classical imprints on quasinormal mode spectra
Fil Simovic, Daniel R. Terno
We compute quasinormal mode frequencies for static limits of physical black holes - semi-classical black hole solutions to Einstein-Hilbert gravity characterized by the finite form…
