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…

A Weyl's law for black holes
José Luis Jaramillo, Rodrigo P. Macedo, Oscar Meneses-Rojas +2
We discuss a Weyl's law for the quasi-normal modes of black holes that recovers the structural features of the standard Weyl's law for the eigenvalues of Laplacian-like operators i…
