Computing nonlinearity ratios using second order black hole perturbation theory
Jasveer Singh, Vardarajan Suneeta
We revisit an analytical approximation scheme for computing nonlinearity ratios involving quadratic quasinormal modes (QQNMs). We compute these ratios for the general case when the…
The Black hole Black string phase transition in Einstein-Gauss-Bonnet gravity
Sreejith Nair, Vardarajan Suneeta
We investigate the presence of a black hole black string phase transition in Einstein Gauss Bonnet (EGB) gravity in the large dimension limit. The merger point is the static spacet…
Nonlinear perturbations of higher dimensional anti-de Sitter spacetime
Dhanya S. Menon, Vardarajan Suneeta
We study nonlinear gravitational perturbations of vacuum Einstein equations, with in dimensions, with , generalizing previous studies for . We follow the fo…
Gravitational Perturbations in a cavity: Nonlinearities
Dhanya S. Menon, Vardarajan Suneeta
Motivated by recent studies of nonlinear perturbations of asymptotically anti-de Sitter spacetimes, we study gravitational perturbations of dimensional Minkowski spacetime…
Study of Semiclassical Instability of the Schwarzschild AdS Black Hole in the Large Limit
Amruta Sadhu, Vardarajan Suneeta
We analyze the semiclassical stability of the Schwarzschild AdS black hole in the Euclidean partition function approach. We perform this computation in the large limit and focu…
Necessary conditions for an AdS-type instability
Dhanya S. Menon, Vardarajan Suneeta
In this work, we analyze the necessary conditions for a nonlinear AdS-type instability in the gravity-scalar field system. In particular, we discuss the necessary conditions for a…
