| Resumo | |
We employ the isomonodromic method to study linear scalar massive perturbations of Kerr black holes for generic scalar masses M mu and generic black hole spins a/M. We find that the longest-living quasinormal mode and the first overtone coincide for (M mu )c similar or equal to 0.370 4981 and (a/M)c similar or equal to 0.999 466 0. We also show that the longest-living mode and the first overtone change continuously into each other as we vary the parameters around the point of degeneracy, providing evidence for the existence of a geometric phase around an exceptional point. We interpret our findings through a thermodynamic analogy. (AU) | |
