Perturbations of black holes generate fluctuations in spacetime known as gravitational waves. In observational astronomy, the spectra of these waves can now be measured through interferometric experiments such as LIGO and VIRGO. In our approximately asymptotically flat universe, the spectra of quasinormal modes in the two existing channels of black hole perturbations— longitudinal and transverse—are related by the so-called isospectrality property. In this talk, I will present a new, rigorous, and universal spectral duality relation that connects the quasinormal mode spectra of black holes in spacetimes with a negative cosmological constant. Through the AdS/CFT correspondence, this gravitational relation implies a series of nontrivial constraints on the spectra of quantum field theories exhibiting S-duality (or particle–vortex duality), as well as on conformal field theories with double-trace deformations.
