Quasinormal modes from D1-D5 CFT

Debodirna Ghosh
Chennai Mathematical Institute.


In this talk, I will explain

(i) the probe scalar Quasinormal modes (QNM) of a class of three-charge microstate geometries and show that the mode spectrum includes slow decaying modes pointed out by Eperon, Reall and Santos.

(ii) Further, I will explain the behaviour of the QNMs by studying the scalar wavefunction in detail.

(iii) Finally, I will show that the mode spectrum can be reproduced from a D1-D5 CFT analysis.
