Quasi-Normal Modes for Logarithmic Conformal Field Theory
Ivo Sachs
We generalize the one-to one correspondence between quasi normal modes in 3- dimensional anti deSitter black holes and the poles of the retarded correlators in the boundary conform…

Quasi-Normal Modes in Topologically Massive Gravity
Ivo Sachs, Sergey N. Solodukhin
We determine the black hole quasi-normal mode spectrum for tensor perturbations in topologically massive AdS-gravity. In the special case of chiral gravity quasi-normal modes are a…

Resolution of Curvature Singularities in Higher Derivative Gravity
Philipp Höffer v. Loewenfeld, Ivo Sachs
We consider possible resolutions of singularities in a contracting anisotropic universe for a class of higher derivative gravity theories. We give evidence that for our models the…
