Scalar field propagation in higher dimensional black holes at a Lifshitz point

We study the complete time evolution of scalar fields propagating in space-times of higher dimensional Lifshitz Black Holes with dynamical critical exponent \(z=2\), obtained from a theory including the most general quadratic curvature corrections to Einstein-Hilbert gravity in \(D\) dimensions. We also computed the quasinormal spectrum after performing a numerical integration and solving exactly the Klein-Gordon equation obeyed by the massive scalar field. We found that quasinormal modes are purely imaginary for all dimensions.
