Quasinormal modes of supersymmetric microstate geometries from the D1-D5 CFT

B Chakrabarty, D Ghosh, A Virmani - Journal of High Energy Physics, 2019 - Springer
A bstract We revisit the study of the probe scalar quasinormal modes of a class of three-
charge super-symmetric microstate geometries. We compute the real and imaginary parts of …

[HTML][HTML] Positivity of discrete information for CHL black holes

S Govindarajan, S Samanta, P Shanmugapriya… - Nuclear Physics B, 2023 - Elsevier
Black holes carry more information about the microstates than just the total degeneracy. As a
concrete example, the Z N-twined helicity trace indices for 1 4-BPS black holes of the CHL …
