Quasinormal modes of supersymmetric microstate geometries from the D1-D5 CFT
TL;DR: In this article, the authors revisited the study of the probe scalar quasinormal modes of a class of three-charge super-symmetric microstate geometries and showed that these modes correspond to slow leakage of excitation from AdS throat to infinity.
Journal ArticleDOI
First law of black hole mechanics with fermions
TL;DR: In this article, the first law of black hole mechanics and the construction of the Lorentz-diffeomorphism Noether charges in the presence of fermionic fields are explored.

TL;DR: In this paper, Sen et al. extended their study to N = 4 CHL orbifold models and identified hair modes in the untwisted as well as twisted sectors, and they showed that after removing the contributions of the hair modes from the microscopic partition functions, the 4d and 5d horizon partition functions agree.
