Mutual Information from Modular Flow in General CFTs
César A. Agón, Pablo Bueno, Adem Deniz Piskin +1
The vacuum mutual information (MI) of subregion algebras provides a universal window into the data of general conformal field theories (CFTs). Exploiting the geometric nature of th…

Amplification of new physics in the quasinormal mode spectrum of highly-rotating black holes
Pablo A. Cano, Marina David, Guido van der Velde
We show that perturbatively-small higher-derivative corrections to the Einstein-Hilbert action can lead to order-one modifications of the quasinormal mode spectrum of near-extremal…

Eikonal quasinormal modes of highly-spinning black holes in higher-curvature gravity: a window into extremality
Pablo A. Cano, Marina David, Guido van der Velde
We carry out the first computation of gravitational quasinormal modes of black holes with arbitrary rotation in a theory with higher-derivative corrections. Our analysis focuses on…
