A geometric approach to QNMs in optics: application to pseudospectrum and structural stability
Lamis Al Sheikh, José Luis Jaramillo
We develop a geometric--spectral framework for the computation and stability analysis of quasi-normal modes (QNMs) in open optical cavities of compact support. The hyperboloidal ap…
Asymptotics and Universality in Black Holes: from the quasinormal Weyl's law to the binary merger waveform
José Luis Jaramillo, Lamis Al Sheikh, Jérémy Besson +7
Current state-of-the-art approaches to black hole (BH) dynamics, encompassing several effective approximation schemes, offer a remarkable control of the quantitative aspects of str…
Integrability in Perturbed Black Holes: Background Hidden Structures
José Luis Jaramillo, Michele Lenzi, Carlos F. Sopuerta
In this work we investigate the presence of integrable hidden structures in the dynamics of perturbed non-rotating black holes (BHs). This can also be considered as a first step in…
Structural aspects of the anti-de Sitter black hole pseudospectrum
Valentin Boyanov, Vitor Cardoso, Kyriakos Destounis +2
Black holes in anti-de Sitter spacetime provide an important testing ground for both gravitational and field-theoretic phenomena. In particular, the study of perturbations can be u…
