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…

Causal Structure of Higher Curvature Gravity
Mohd Ali, Vardarajan Suneeta
In this paper, we analyze the causal structure of Generalized Quadratic Gravity (GQG) and Einsteinian Cubic Gravity (ECG). It is well known that gravitons in higher-curvature theor…

A local Generalized second law in crossed product constructions
Mohd Ali, Vardarajan Suneeta
In this paper, we show a local generalized second law (the generalized entropy is nondecreasing) in crossed product constructions for maximally extended static and Kerr black holes…
